note 47475 added to function.in-array

Some very helpfuly variant's, of functions: class shared { /**lordfarquaad at notredomaine dot net 09-Sep-2004 11:44 * @return bool * @param mixed $needle * @param mixed $haystack * @desc This function will be faster, as it doesn't compare all elements, it stops when it founds the good one. It also works if $haystack is not an array :-) */ function in_array_multi($needle, $haystack) { if(!is_array($haystack)) return $needle == $haystack; foreach($haystack as $value) if(shared::in_array_multi($needle, $value)) return true; return false; } /**lordfarquaad function's variant1 * @return bool * @param string $needle_key * @param mixed $haystack * @desc Search a key in the array and return if founded or not. */ function in_array_key_multi($needle_key, $haystack) { if(!is_array($haystack)) return $needle_key == $haystack; foreach($haystack as $key => $value) { $value; // TODO: Extract the $key without seting $value if(shared::in_array_key_multi($needle_key, $key)) return true; } return false; } /**lordfarquaad function's variant2 * @return bool * @param string $needlekey * @param mixed $needlevalue * @param mixed[optional] $haystack_array * @param string[optional] $haystack_key * @param mixed[optional] $haystack_value * @desc Search in array for the key and value equal. */ function in_array_multi_and_key($needlekey, $needlevalue, $haystack_array = null, $haystack_key = null, $haystack_value = null) { if (!is_array($haystack_array)) return ($needlekey == $haystack_key and $needlevalue == $haystack_value); foreach ($haystack_array as $key => $value) if (shared::in_array_multi_and_key($needlekey, $needlevalue, $value, $key, $value)) return true; return false; } } HOW TO USE: shared::in_array_multi(......) it's very simple. ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47475 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47475&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47475&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47475&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47475&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47475&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47475&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47475&report=yes Search -- http://master.php.net/manage/user-notes.php
