Using String Matching vs. Pattern Matching

 
<?php 

$value = "my username"; 
if (strcmp($value, "user") == 0) { 
    echo "Found match in '" . $value . "' using strcmp.\n"; 
} else { 
    echo "Didn't find match in '" . $value . "' using strcmp.\n"; 
} 
if (!(strrpos($value,"user") ==="false)) {
    echo "Found match in '" . $value . "' using strrpos.\n"; 
} else { 
    echo "Didn't find match in '" . $value . "' using strrpos.\n"; 
} 
if (ereg("\<user\>", $value)) { 
    echo "Found match in '" . $value . "' using ereg.\n"; 
} else { 
    echo "Didn't find match in '" . $value . "' using ereg.\n";
