My first post on php.net. Hope someone finds it helpfull. These few functions will serialize and
unserialize arrays and objects. It works recursively too. I call them "might_..."
because they test to see if any action is required.
<?php
function might_serialize($val){
if(is_object($val)){
$obj_keys = array_keys(get_object_vars($val));
foreach($obj_keys as $k){ $val->$k = might_serialize($val->$k); }
$val = serialize($val);
}
if(is_array($val)){
foreach($val as &$v){ $v = might_serialize($v); }
$val = serialize($val);
}
return $val;
}
function might_unserialized($val){
//$pattern = "/.*\{(.*)\}/";
if(is_serialized($val)){
$ret = unserialize($val);
foreach($ret as &$r){
$r = might_unserialized($r);
}
return $ret;
}else { return $val; }
}
function is_serialized($val){
if (!is_string($val)){ return false; }
if (trim($val) == "") { return false; }
//if (preg_match("/^(i|s|a|o|d)(.*);/si",$val)) { return true; }
if (preg_match("/^(i|s|a|o|d):(.*);/si",$val) !== false) { return true; }
return false;
}
?>
