json_decode()
json_decode() decodes a JSON string into a data structure.
In case an error arise during parsing, a null value is returned, as the default value. This error may be confused with the decoding of the 'null' string, which is a valid JSON value. It may also raise a ValueError, when the function is configured by JSON_THROW_ON_ERROR.
<?php
$json = '[1,2,3]';
try {
$variable = json_decode($json, flags: JSON_THROW_ON_ERROR);
} catch(ValueError $e) {
print "JSON decoding error";
}
// $variable === [1,2,3];
?>
