Best Answer
You can use the
strpos()
function which is used to find the occurrence of one string inside another one:Note that the use of
!== false
is deliberate (neither!= false
nor=== true
will return the desired result);strpos()
returns either the offset at which the needle string begins in the haystack string, or the booleanfalse
if the needle isn't found. Since 0 is a valid offset and 0 is "falsey", we can't use simpler constructs like!strpos($a, 'are')
.Now with PHP 8 you can do this using str_contains:
