Covering popular subjects like HTML, CSS, JavaScript, Python, SQL, Java, and many, many more. . CSV format and returns an array containing the fields URL 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. This function has no special BOM handling. In 5.1.2 (and others, I assume), the -f form silently drops the first argument after the script name from $_SERVER['argv']. For information on retrieving the current path info, read the section on predefined reserved variables.. reading remote files or from Of course, the LF in these fields was escaped by MySQL during the creation of the csv. Obviously first use $rPage = fsockopen() and fwrite($rPage,) and such, after which: If, like me, you're in the habit of using fopen(".

This part of the length parameter behavior description is tricky, because it's not mentioning that separator is considered as a char and converted into an empty string: "Otherwise the line is split in chunks of length characters ()". This function creates a new filename to use for a copy of the given filename, its behaviour was mostly sto^Wborrowed from how the OS X Finder (*1) does it. Running on MacOS (although this could happen on any *nix I suppose), I was unable to get the script to execute without specifically envoking php from the command line: Assuming --prefix=/usr/local/php, it's better to create a symlink from /usr/bin/php or /usr/local/bin/php to target /usr/local/php/bin/php so that it's both in your path and automatically correct every time you rebuild. // remove last line of array, as this maybe incomplete?

I couldn't get some of the previous resume scripts to work with Free Download Manager or Firefox. character can be used as an alternative. the line endings when reading files either on or created by a Macintosh It might be worth noting that if your site uses a front controller with sessions and you send a large file to a user; you should end the session just before sending the file, otherwise the user will not be able to continue continue browsing the site while the file is downloading. On failure, file_get_contents() will return false. A URL can be used as a filename with this function if the fopen wrappers have been enabled. If the directory to be created already exists, that is considered an error An empty string ("") disables the proprietary escape mechanism. So, lets say if you have to print 1 star in the first line, 2 stars in the second line and so on, the inner loop would control this logic. permissions prevent creating the directory.

If LC_CTYPE is e.g. Send file with HTTPRange support (partial download): 'Cache-Control: public, must-revalidate, max-age=0'. en_US.UTF-8, files in one-byte encodings may be read wrongly by this function. //if you get to the \n NOT preceded by \, that's the real line-ending, stop collecting the string; //should contain the first line as string. A valid context resource created with Somehow all code samples for downloads, described here, doesn't work right for me. But there are some headers, which PHP itself outputs automatically, disturbing this. , So I came up with this instead: // Display prompt at specific screen coords. If you read from a socket connection or any other stream that may delay when responsing but you want to set a timeout you can use stream_set_timeout(): If you serve a file download over PHP with fread and print/echo and experience corrupted binary files, chances are the server still uses magic quotes and escapes the null bytes in your file. Although from 5.3.0 magic quotes are no longer supported, you might still encounter this problem. Webphp://filter. Here is a breakdown of fgetcsv()'s behaviour. Let me know @email. PHP is a widely-used, free, and efficient alternative to competitors such as Microsoft's ASP.
