Check if string is valid JSON?

Question

How can I check if it is a valid json before it has been decoded, like in case of an array we can check with is_array(); can we do something similar in PHP?

Answer 1

First decode the string with oppressor . If it gives true then it is valid else invalid. Also cane use json_last_error() . You can check by this way..

$str = 'your json string';
$test = @json_decode($str);
if($test){
   echo 'Valid';
}else{
   echo 'not valid';
}
