#47681 [NEW]: System TMP dir ignored in file uploads

From: ulrich at cs dot auckland dot ac dot nz Operating system: Win XP Pro PHP version: 5.2.9 PHP Bug Type: *Web Server problem Bug description: System TMP dir ignored in file uploads Description: ------------ File upload under Apache 2.2.8 and 2.2.11 produces an empty temporary file name and an UPLOAD_ERR_NO_TMP_DIR error in $_FILES[<userfile>]['error']. In the case of the machine concerned, Apache and PHP run off the D: drive whereas the temporary directories reside under C:. Rebooting the entire system sometimes resolves the problem temporarily, but it then reappears. This does not always work, however. Repeat "uploads" occasionally cause the server to crash. Setting the temporary directory explicitly using upload_tmp_dir provides a workaround. Default windows system tmp dir variables are set as: TEMP=C:\WINDOWS\TEMP TMP=C:\WINDOWS\TEMP Reproduce code: --------------- <?php if (count($_FILES) > 0) { echo "<h1>Response page</h1>"; echo "<h2>\$_ENV</h2>"; foreach ($_ENV as $name => $value) echo $name."=".htmlentities($value)."<br/>"; echo "<h2>\$_FILES</h2>"; foreach ($_FILES["myFile"] as $fileProperty => $filePropertyValue) { echo $fileProperty."=".$filePropertyValue."<br>"; } } else { ?> <h1>Form</h1> <form action="fu.php" method="post" enctype="multipart/form-data"> Please enter a file: <input type="file" name="myFile"> <input type="submit" value="Submit file for processing"> </form> <?php } ?> Expected result: ---------------- $_ENV ... TEMP=C:\WINDOWS\TEMP TMP=C:\WINDOWS\TEMP ... $_FILES name=figure1-e.pdf type=application/pdf tmp_name=C:\WINDOWS\Temp\php981.tmp error=0 size=50452 Actual result: -------------- $_ENV ... TEMP=C:\WINDOWS\TEMP TMP=C:\WINDOWS\TEMP ... $_FILES name=figure1-e.pdf type= tmp_name= error=6 size=0 -- Edit bug report at http://bugs.php.net/?id=47681&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47681&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47681&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47681&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47681&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47681&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47681&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47681&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47681&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47681&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47681&r=support Expected behavior: http://bugs.php.net/fix.php?id=47681&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47681&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47681&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47681&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47681&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47681&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47681&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47681&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47681&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47681&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47681&r=mysqlcfg
