What PHP functions can be used to find the position of specific substrings within a string?

To find the position of specific substrings within a string in PHP, you can use the strpos() function. This function searches for the first occurrence of a substring within a string and returns the position of the substring if found. If the substring is not found, it returns false. Another function that can be used is the stripos() function, which is case-insensitive. 

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

$position = strpos($string, $substring);

if ($position !== false) {
    echo "The substring '$substring' was found at position $position.";
} else {
    echo "The substring '$substring' was not found in the string.";
}
