Question

String comparison in PHP seems little difficult. I don’t know if any other ways to do it.

For example say:

$t1 = "CEO";
$t2 = "Chairman";
$t3 = "Founder";

$title = "CEO, Chairman of the Board";

if (!strcmp($t1, $title)) {
    echo $title."<br>"; echo $Fname."<br>"; echo $Lname."<br>";
} else if (!strcmp($t2, $title)) {
    echo $title."<br>"; echo $Fname."<br>"; echo $Lname."<br>";
} else if (!strcmp($t3, $title)) {
    echo $title."<br>"; echo $Fname."<br>"; echo $Lname."<br>";
}

This isn’t giving any result as above $title has word $t1 and $t2 in it. How can I do this?

The strcmp() tests on exact equality. You rather want to test if the string contains the given part. In that case rather use stripos() or stristr(). Both can be used the following way:

if (stripos($title, $t1) === false) {
    // $title does not contain $t1
}
if (stristr($title, $t1) === false) {
    // $title does not contain $t1
}

When you want case sensitive comparison (e.g. chairman should not be equal to Chairman), then use strpos() or strstr() instead.
