examples of the STRCMP() function in php
Example 1. In this example, we compare two strings (case-sensitive).
<?php
echo strcmp("Hello world!","Hello world!");
?>Example 2. In this example, we compare two strings (case-sensitive = Hello and hELLo will not output the same).
<?php
echo strcmp("Hello","Hello");
echo "<br>";
echo strcmp("Hello","hELLo");
?>Example 3. In this example, we use different return values.
<?php
echo strcmp("Hello world!","Hello world!"); // the two strings are equal
echo strcmp("Hello world!","Hello"); // string1 is greater than string2
echo strcmp("Hello world!","Hello world! Hello!"); // string1 is less than string2
?>
