Well, no one answered.

You go straight to the code, let's see what's wrong.

"Zgy 90°" just wants to remove the symbol of this string.

Code 1

$str = "Zgy 90°"; Echo str_replace (' ° ', ' ', $str);

：

$str = "dfdfsdsf°°°°zgy°°°°90°"; Echo str_replace (' ° ', ', $str). "
echo preg_replace ('/(°) +/', ', $str);

Strange I also used the str_replace, the result is not right, according to you give this to solve
Thank you so much!
