SyntaxError: JSON. parse: unexpected character at line 1 column 1 of the JSON data, syntaxerrorjson

SyntaxError: JSON. parse: unexpected character at line 1 column 1 of the JSON data, syntaxerrorjson

An error occurred yesterday. The frontend initiates ajax and the backend php returns json data. The result is an error message in firebug:

SyntaxError: JSON. parse: unexpected character at line 1 column 1 of the JSON data

Solution:

On the php server, add a line of code before the output:

Ob_end_clean ();

Clear the bom header of utf8
