In what scenarios would it be advisable to use the strpos() function over other methods for checking text presence in PHP?

The strpos() function is particularly useful when you need to check for the presence of a specific substring within a larger string in PHP. It returns the position of the first occurrence of a substring within a string, or false if the substring is not found. This makes it a simple and efficient way to determine if a certain text is present in a given string. 

$haystack = "Hello, World!";
$needle = "Hello";

if(strpos($haystack, $needle) !== false) {
    echo "The substring was found in the string.";
} else {
    echo "The substring was not found in the string.";
}
