En mi código, a veces PhpStorm agrega caracteres extraños, por ejemplo, "`/".

Mi codigo original:

 $.ajax({ type: 'POST', url: 'actions/tests/submitAnswer.php?question_id=' + question_id + '&fill_test_answers=' + test_time_mode, data: $('#submitQuestion').serialize(), success: function (data) { /* ... */ } });

Mi código en el navegador web:

 $.ajax({ type: 'POST', url: 'actions/tests/submitAnswer.php?question_id=' + question_id`/ + '&fill_test_answers=' + test_time_mode, data: $('#submitQuestion').serialize(), success: function (data) { /* ... */ } });
