What is the best approach to implement the check for a period in PHP, especially for someone new to PHP programming?

To check for a period in PHP, especially for beginners, you can use the strpos() function to search for a period (.) in a string. This function returns the position of the first occurrence of a substring within a string. If the period is found, it will return the position, otherwise it will return false. 

$string = "Hello World.";
if(strpos($string, '.') !== false){
    echo "Period found in the string.";
} else {
    echo "Period not found in the string.";
}
