Check If String Contains Exact Substring Php Code Example

Example 1: php check if string contains word

$myString = 'Hello Bob how are you?'; if (strpos($myString, 'Bob') !== false) {     echo "My string contains Bob"; }

Example 2: php contains substring

<?php $mystring = 'abc'; $findme   = 'a'; $pos = strpos($mystring, $findme);  // Note our use of ===.  Simply == would not work as expected // because the position of 'a' was the 0th (first) character. if ($pos === false) {     echo "The string '$findme' was not found in the string '$mystring'"; } else {     echo "The string '$findme' was found in the string '$mystring'";     echo " and exists at position $pos"; } ?>
