1.2.1358. Use str_contains()¶
str_contains() checks if a string is within another one. It replaces a call to strpos() with a comparison.
Note that this function is case sensitive : it cannot replace stripos().
Note that this function is single-byte only : it cannot replace mb_strpos().
This analysis omits calls to strpos() that are saved to a variable. strpos() is actually returning the position of the found string in the haystack, which may be reused later.
<?php
if (str_contains("abc", "a")) { doSomething(); }
// strpos is used only for detection.
if (strpos("abc", "a") !== false) { doSomething(); }
// strpos returns a position,
$pos = strpos("abca", "a", 3);
if ($pos > 3) { doSomething();
?>
