note 58974 added to function.array-search

A quick-and-dirty array_search_all() that i used for a small dup-checking routine. there are many, many ways to do something like this, not the worst of which would be to use a relational database for a dataset any larger than this ;) -mark meves <?php /** @return array of zero or more keys form $aHaystack whose values match $mScalarNeedle using a '==', (ie not strict) comparison */ function array_search_all($mScalarNeedle,$aHaystack){ return array_keys( array_filter($aHaystack, create_function('$v','return $v == \''.addslashes($mScalarNeedle).'\';') )); } /* test it: */ $aNicknames = array('jimmy'=>1,'james'=>1,'jim'=>1, 'billy'=>2,'william'=>2,'bill'=>2); foreach(array('jim','bill') as $sName){ echo "variations for \"$sName\" :(". implode(', ', array_search_all($aNicknames[$sName],$aNicknames)). ")\n"; } /* outputs: variations for "jim" are (jimmy, james, jim) variations for "bill" are (billy, william, bill) */ ?> ---- Manual Page -- http://www.php.net/manual/en/function.array-search.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58974 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58974&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58974&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58974&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58974&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58974&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58974&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58974&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58974&report=yes Search -- http://master.php.net/manage/user-notes.php
