#25074 [Opn->Bgs]: addslashes() fails for large data

ID: 25074 Updated by: iliaa@php.net Reported By: sandeepc at myrealbox dot com -Status: Open +Status: Bogus Bug Type: Performance problem Operating System: Linux 2.4.9 PHP Version: Irrelevant New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. This sounds like a configuration issue, possibly having to do with the memory limit.

We tested with data size ranging form 4MB to 100 MB.It would fail around 36 MB of data. I have'nt tested this in the latest releases, however. From phpinfo(): PHP Version 4.2.3 System: Linux linuxbuild 2.4.9-e.3smp #1 SMP Fri May 3 16:48:54 EDT 2002 i686 Build Date Apr 29 2003 17:44:32 Server API Apache Virtual Directory Support disabled Thread Safety disabled Configure Command './configure' '--enable-shared=all' '--disable-static' '--enable-memory-limit=yes' '--enable-magic-quotes=yes' '--enable-debug=no' '--enable-inline-optimization' '--enable-mbstring' '--enable-safe-mode' '--enable-sigchild' '--enable-sysvsem' '--enable-sysvshm' '--enable-shmop' '--enable-track-vars' '--enable-gd-native-ttf' '--enable-gd-imgstrttf' '--with-gd' '--with-xml' '--with-dom' '--with-ttf' '--with-gettext' '--with-ldap' '--with-curl' '--with-mcrypt' '--without-mysql' '--without-imap' '--with-pgsql' '--with-apxs' Reproduce code: --------------- <?php if ($upload){ $size=filesize($uploaded_data); $data = ""; if (is_uploaded_file($uploaded_data)){ if ($fp = fopen($uploaded_data, "r")){ $data = fread($fp,$size); fclose($fp); addslashes($data); print "Hello World"; }// end if (able to get uploaded file) } } else{ ?> <html> <form method="POST" enctype="multipart/form-data" name="testform"> <input type="hidden" name="MAX_FILE_SIZE" value="104857600"> <input type="file" name="uploaded_data" size="30"><br><br> <input type="submit" name="upload" value="Upload"> </form> </html> <?php } ?> Expected result: ---------------- We are storing the uploaded file into a table(Postgres). The uploaded data needs to be addslashes()'d before storing into the database. Actual result: -------------- There is no error in the error log, however the php hangs. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25074&edit=1
