PHP Determines whether a string contains the specified character (for efficient writing)

PHP Determines whether a string contains the specified character. Cases:

$str = "Pussssasasasds";

Judging whether or not a $str contains abchjgkoqtvwxyz any character also says whether Str contains a or B or C or H or J, and so on. Case insensitive. For the most efficient writing thanks.

What I can think of is if else ... I feel so stupid. Ask for an open-minded and efficient way of thinking

With the regular

if (Preg_match ('/[abchjgkoqtvwxyz]/i ', $str)) {  echo ' contains ';}
