Req #55654 [NEW]: ereg() behavior for preg_match

From: Operating system: Windows 7 PHP version: 5.3SVN-2011-09-09 (snap) Package: Regexps related Bug Type: Feature/Change Request Bug description:ereg() behavior for preg_match Description: ------------ Consideration. I choosen "September Snapshot", because I could not find mine in the list. My installation report to "PHP 5.3.3. Build Date: Jul 21 2010 20:25:38". Alright. I would like to ask, if is there any possibility to add, maybe through another non-Perl compatible modifier, the behavior we had with ereg(). The behavior I'm talking about refers to match as much as possible instead of stop at very first valid match. This is useful sometimes. In my case, specially to validate input data against a RFC specification. Look at this snippet: https://ideone.com/sC6mA I tried to make it as much specific as I could. The intention was to validate float point numbers, between zero and 1, with none and up to three decimals, denying invalid floats, such as 0.00 (same as zero) or 1.0 (same as 1). But, the "lazy" behavior of preg_match() is accepting the code above, where 0.3444 should be denied, because of its 4 decimals. But since 0.344 is valid in the last length verification (one and up to three), the function accepts the input data, and the last digit is simply ignored, because preg_match() already caracterized 0.344 as valid. I hope you understand Expected result: ---------------- An empty array Actual result: -------------- A match -- Edit bug report at https://bugs.php.net/bug.php?id=55654&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55654&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55654&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55654&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55654&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55654&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55654&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55654&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55654&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55654&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55654&r=support Expected behavior: https://bugs.php.net/fix.php?id=55654&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55654&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55654&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55654&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55654&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55654&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55654&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55654&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55654&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55654&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55654&r=mysqlcfg
