Question

I’m trying to remove from a string variable, a character that appeared between spaces, I used some PHP functions to do it like str_replace but nothing happens.

An example below, I show it through var_dump PHP function :

string '�I�N�S�E�R�T� �[�d�b�o�]�

If anyone can tell me a way to do this, I’d be grateful.

You could try:

$str = '�I�N�S�E�R�T� �[�d�b�o�]�';
$filtered_str = filter_var($str, FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_LOW | FILTER_FLAG_STRIP_HIGH)

Demo. See: filter-var and filter.filters.sanitize
