How can the use of var_dump instead of echo help in debugging strpos related issues in PHP?

When debugging strpos related issues in PHP, using var_dump instead of echo can help because var_dump will display the type and value of the variable being checked, making it easier to identify any unexpected results. This can help pinpoint the exact position where strpos is failing, such as returning false instead of the expected position of a substring within a string.

$string = "Hello, World!";
$substring = "World";

// Using var_dump to debug strpos related issues
$result = strpos($string, $substring);
var_dump($result);
