Bug #53402 [NEW]: "." is converted to "_" in <input type="file" name="test.txt">

From: Operating system: Mandriva 2010 spring PHP version: 5.2.14 Package: *General Issues Bug Type: Bug Bug description:"." is converted to "_" in <input type="file" name="test.txt"> Description: ------------ If a the <name>-tag of an <input> contains a dot, if is transferred to an underscore. I googled all around, but can't find anything. I wonder because: $test = array( 'title_image.img'=>'bla'); works. So why it is converted? Is it a bug or a feature :-)? Test script: --------------- <html> <head> <title>Test</title> </head> <body> <pre> <?php echo $_FILES['title_image.img']['name']; var_dump( $_FILES); ?> </pre> <form name="form" method="post" action="" enctype="multipart/form-data"> <input type="file" name="title_image.img" /> <input type="submit" name="save" value="Speichern" /> </form> </body> </html> Expected result: ---------------- array(1) { ["title_image.img"]=> array(5) { ["name"]=> string(0) "" ["type"]=> string(0) "" ["tmp_name"]=> string(0) "" ["error"]=> int(4) ["size"]=> int(0) } } Actual result: -------------- Notice: Undefined index: title_image.img in /media/DATA/home/mschmitz/public_html/customer/uni/fm/tischlerei/test.php on line 9 array(1) { ["title_image_img"]=> array(5) { ["name"]=> string(0) "" ["type"]=> string(0) "" ["tmp_name"]=> string(0) "" ["error"]=> int(4) ["size"]=> int(0) } } -- Edit bug report at http://bugs.php.net/bug.php?id=53402&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53402&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53402&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53402&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53402&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53402&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53402&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53402&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53402&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53402&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53402&r=support Expected behavior: http://bugs.php.net/fix.php?id=53402&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53402&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53402&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53402&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53402&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53402&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53402&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53402&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53402&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53402&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53402&r=mysqlcfg
