note 57385 added to function.ereg

A previous post stated "Beware that eregs in PHP4 are broken, for instance if you want to match "a to z, 0,9 and -" you might want to use [a-z0\\-9] but it will silently fail due to a bug" This is incorrect, this is not a bug, nor is ereg broken on this count! In my testing of ereg, matching -' [' or `]' within a bracketed expression ereg works exactly according to the regex man page http://www.tin.org/bin/man.cgi?section=7&topic=regex referred from the php manual page at http://au3.php.net/manual/en/ref.regex.php From the regex man page you will find that within a bracketed expression to match a literal ]' make it the first character (following a possible ^'). To include a literal -' make it the first or last character, or the second endpoint of a range. To use a literal -' as the first endpoint of a range, enclose it in [.' and .]' spook says if you want a string to work that matches "a to z", "A to Z", "0 to 9", "-", "[", "]" and "_" you will have to use this expression: ([0-9a-zA-Z_]|\\-|\\[|\\]) end spook says A neater solution is []0-9a-zA-Z_[-] I hope this settles that ereg is not buggy or broken in this way ---- Manual Page -- http://www.php.net/manual/en/function.ereg.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57385 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57385&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57385&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57385&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57385&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57385&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57385&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57385&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57385&report=yes Search -- http://master.php.net/manage/user-notes.php
