Check if string is serialized in PHP
php, serialization
Solution
$array = @unserialize($string);
if ($array === false && $string !== 'b:0;') {
// woops, that didn't appear to be anything serialized
}
The `$string !== 'b:0;'` checks to see if the serialized string may have been the value `false`. If this check is important to you you may want to `trim` the serialized string or otherwise preprocess it to make sure this works.
Problem
I am in the middle of building a cache layer for the Redis DB to my application and I have come to the point where's it's about to take care of arrays. I wonder if there's any good (high performance!) way of controlling an string to be serialized or not with PHP? Thanks a lot!
