If you are using an Apache, it's quite simple to figure out the correct mime type. // $fURI: URL to a file located on a web server, // set request header for GET with referrer for modified files, that follows redirects, // HTTP request completed, preserve system error, if any, // Parse HTTP Response Headers for HTTP Status, as well filename, type, date information, // HTTP Status header means we have reached beginning of response headers for last request, '@filename\\s*=\\s*(?|"([^"]+)"|([\\S]+));?@ims'. If you do, all null bytes will become \0, and you might get surprising results when unpacking. Here is a breakdown of fgetcsv()'s behaviour. The readfile is always completed even if it exceed the default 30 seconds limit, then the script is aborted. WebTells PHP whether to declare the argv & argc variables (that would contain the GET information). I did some clean up and modified the code a little. the CSV file (allowing for trailing line-end characters). So for the default parameter If you edit a php file in windows, upload and run it on linux with command line method. WebSimilar to fgets() except that fgetcsv() parses the line it reads for fields in CSV format and returns an array containing the fields read.. // Here, $buf is guaranted to contain data. referenced by stream. Covering popular subjects like HTML, CSS, JavaScript, Python, SQL, Java, and many, many more. fopen() mode parameter. Example #1 Read and print the entire contents of a CSV file, Gets line from file pointer and parse for CSV fields, If PHP is not properly recognizing Webpathinfo() returns information about path: either an associative array or a string, depending on flags. bytes delivered like readfile() does. On systems which differentiate between binary and text files "php://filter/resource=http://www.example.com", "php://filter/read=string.toupper/resource=http://www.example.com", "php://filter/read=string.toupper|string.rot13/resource=http://www.example.com", "php://filter/write=string.rot13/resource=example.txt". / I had a fread script that hanged forever (from php manual): This is an hack I've done to download remote files with HTTP resume support. If you try to copy a file to itself - e.g. Just a note for those who face problems on names containing spaces (e.g. // Progress file pointer and get first 3 characters to compare to the BOM string. Also, i don't know if this is a bug or what but it appears that fgets() reads until the new line anyway. Returns true on success or false on failure. In-case anyone is having difficulty working around Byte-order-marks, the following should work. To use fgetcsv() with a string instead of a file, you can use the data: wrapper. even meant to escape itself. It's for UTF-8 only, //en.wikipedia.org/wiki/Byte_order_mark has more information if you are dealing with other code-pages, Here is an example how to use this function with generators. The optional escape parameter sets the escape character (at most one single-byte character). ini_set('auto_detect_line_endings', 1); fixed it. It's worth noting that copy() sets the destination file's last modified time/date. computer, enabling the will be 3 bytes longer than expected. I have test it on code igniter. With that security in mind, the suggestion of a 302 redirection seems like a risky idea. //workaround for IE filename bug with multiple periods / multiple dots in filename, //This will set the Content-Type to the appropriate setting for the file, //check if http_range is sent by browser (or download manager), //multiple ranges could be specified at the same time, but for simplicity only serve the first range, //figure out download piece from range (if set), //set start and end based on range (if set), else set defaults, //Only send partial content header if downloading a piece of the file (IE workaround), //headers for IE Bugs (is this necessary? //track correlation of raw -> nice name so we don't have to do on-the-fly nice name checks, //this is a basic read, you will likely want to change this to accomodate what. The ability to read a file line by line allows us to read large files without entirely storing it to the memory. as an error. See fopen() for more details on how to specify the php://memory reading from a socket stream can be different to the. People used to the 'C' semantics of fgets() should note the difference in how EOF is returned. The permissions is also modified just like on the command line. WebPHP readfile() PHP Filesystem readfile() FALSE '@' Use ftell() to find the current , php://filter Don't forget; you can use copy on remote files, rather than doing messy fopen stuff. streams returned when Something to the effect below, very customizable for private access, remote files, and keeping order of your online media. WebOn Windows (not sure about Linux) copy will overwrite an existing file but will not change the case of the existing filename. I had a problem with multibytes. I can't find a direct way to deal with it, since fgetcsv() doesn't give you a chance to manipulate the line before it reads it and parses itI've had to change all occurrences of '\"' to '" in the file first before feeding ot to fgetcsv(). if i use readfile, the image won't display. # Set the parent multidimensional array key to 0. If LC_CTYPE is e.g. // remove last line of array, as this maybe incomplete? This works great when your header columns are not always in the same order; like when you're processing many feeds from different customers. Here is a simple script that I use for removing and copying non-empty directories. php://input , php://output When reading from anything that is not a regular local file, such as 'test.pl' and just have to type 'test, without the .pl extension' on the windows command line and the command processor knows that it is a perl file and executes it en_US.UTF-8, files in php://stdout php://stderr , php://input Thanks for all the comments, i wrote this function for fully supporting file and directory copy. character can be used as an alternative. I had a problem with the $argv values getting split up when they contained plus (+) signs. of the following conditions is met: A file system pointer resource print echo pathinfo() operates naively on the input string, and is not aware of the actual filesystem, or path components such as ".. Use this: This style is shown as an example on this page and in a number of examples on the Internet: Here is a OOP based importer similar to the one posted earlier. I ended the path variable with a %00, which is the null character. Returns the read string or false on failure. To avoid the risk of choosing themselves which files to download by messing with the request and doing things like inserting "../" into the "filename", simply remember that URLs are not file paths, and there's no reason why the mapping between them has to be so literal as "download.php?file=thingy.mpg" resulting in the download of the file "thingy.mpg". WebW3Schools offers free online tutorials, references and exercises in all the major languages of the web. file() file_get_contents() 8192) is made; depending on the previously buffered data, the size of the This will take product_id and make, //process the header entry so we can map our named header fields to a numerical index, which. has apparently been deprecated. ), 'Content-Disposition: attachment; filename="'. I used fgetcsv to read pipe-delimited data files, and ran into the following quirk. To work around this, we check to see if the User Agent contains MSIE and rewrite the necessary periods as %2E, # workaround for IE filename bug with multiple periods / multiple dots in filename, "Content-Disposition: attachment; filename=. It does work, but you may encounter memory exhaustion using "fread". //get the nice name to use for "get" and "set". You better avoid to use $_SERVER['DOCUMENT_ROOT'], because it will return nothing. already exists. Concerning [problems with UTF-8 and] downloading Zip files I found that simply adding 3 lines of code before starting the fread to the buffer for delivery in all browsers solved the problem. Beware - the chunky readfile suggested by Rob Funk can easily exceed you maximum script execution time (30 seconds by default). 'test.pl' and just have to type 'test, without the .pl extension' on the windows command line and the command processor knows that it is a perl file and executes it using the perl command interpreter. run-time configuration option may help resolve the problem. Note that fread() will return '' (empty string) when a timeout occurs unlike socket_read() which returns false Changing the value of $length may yield to different download speeds when serving a file from a script. In the examples I've used underscores (_) to show spaces and brackets ([]) to show individual fields: // Removes escape characters before both enclosures and escapes, but leaves everything else untouched, similiar to single quoting, // Does NOT remove a lone escape character at the end of a field, // Removes lone escape characters at the end of fields. Must be greater than the longest line (in characters) to be found in CSV format and returns an array containing the fields Returns true on success or false on failure. some hosts disable copy() function and say its for security. 2true So in fact it is not reading a line, but keeps reading untill it finds a \n-character that's not quoted as a field. I was looking for a way to interactively get a single character response from user. If to is a URL, the Use something like ob_end_flush(). I write this script for download with resume suport, // Replace the slash and backslash character with empty string, // Initialize the range of bytes to be transferred, // Check if starting and ending byte is valid, "HTTP/1.1 416 Requested Range Not Satisfiable", '

You can also call the script from the command line after chmod'ing the file (ie: chmod 755 file.php). enctype="multipart/form-data" file_get_contents() as it has much better performance File was windows-1250, script was UTF-8 and set_locale wasn't work so I made a simple and safe workaround: beware of characters of binary value == 0, as they seem to make fgetcsv ignore the remaining part of a line where they appear. If you just want to get the contents of a file into a string, use PHP /IO PHP dunno if this is on linux the same but on windows evertime.
