PHP check if a string is JSON
Simple method will be:
1 2 3 4 5 6 | if( is_array(json_decode($string,true)) ){ echo true;}else{ echo false;} |
This method doesn’t rely on heuristics, uses native php functionality, and is about as future-proof as you’re gonna get; it just tells you straight up whether there were any errors in decoding the string.
1 2 3 4 | function isJson($string) { json_decode($string); return (json_last_error() == JSON_ERROR_NONE);} |
