PHP Serialize to JSON Converter
PHP's serialize() function creates a string representation of a value that can be stored and restored. It is common in WordPress options, session data, and caches. The format encodes type information: s:5:"hello" is a 5-character string, a:2:{...} is an array with 2 elements. This converter handles nested arrays and objects.
