Bug #52197 [NEW]: confusing description of return value 'strpos()'

From: Operating system: ubuntu PHP version: Irrelevant Package: Documentation problem Bug Type: Bug Bug description:confusing description of return value 'strpos()' Description: ------------ I originally submitted the material below this paragraph, but it has been discussed before - WITH the exception of the "" return value. There needs to be some description of circumstances under which "" gets returned. Otherwise it's a random response, and we programmers like finite responses :-) The function prototype on the document page says it returns an INT. The pink warning box at the bottom says it might return INT, BOOL, "". The return type should be set to MIXED. And in what case, given the decscription of this function's operation, would it return an empty string? Test script: --------------- Not needed Expected result: ---------------- n/a Actual result: -------------- n/a -- Edit bug report at http://bugs.php.net/bug.php?id=52197&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52197&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52197&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52197&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52197&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52197&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52197&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52197&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52197&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52197&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52197&r=support Expected behavior: http://bugs.php.net/fix.php?id=52197&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52197&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52197&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52197&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52197&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52197&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52197&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52197&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52197&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52197&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52197&r=mysqlcfg
