如何从php中序列化数据获取“file_url”？

I am looking to get data file_url from this:

a:1:{s:5:"bIrq7";a:6:{s:14:"user_file_name";s:15:"Recruitment.pdf";s:9:"file_name";s:15:"recruitment.pdf";s:9:"file_path";s:76:"/home3/fashion/public_html/thesafetyjobs.com/wp-content/uploads/ninja-forms/";s:8:"file_url";s:71:"http://thesafetyjobs.com/wp-content/uploads/ninja-forms/recruitment.pdf";s:8:"complete";s:1:"1";s:9:"upload_id";s:2:"28";}}`

How can I do this?

Try maybe_unserialize() function this return an array You can try this code

$data = 'a:1:{s:5:"bIrq7";a:6:{s:14:"user_file_name";s:15:"Recruitment.pdf";s:9:"file_name";s:15:"recruitment.pdf";s:9:"file_path";s:76:"/home3/fashion/public_html/thesafetyjobs.com/wp-content/uploads/ninja-forms/";s:8:"file_url";s:71:"http://thesafetyjobs.com/wp-content/uploads/ninja-forms/recruitment.pdf";s:8:"complete";s:1:"1";s:9:"upload_id";s:2:"28";}}';
$un_serialize = maybe_unserialize($data);
echo $un_serialize['bIrq7']['file_url'];
