How do I check if a string contains a specific word?
    $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.";
