Most programming languages have a function that allows you to insert one string into another string at a given position. For example, I can take the string blue and the string HI, and perform an operation blue.insert(HI,2) to get the resulatant string blHIue. But such a function does not come with the standard PHP library, at least not obviously. There is no function str_insert and a simple Google search does not bring any results. So one has to get creative and use the substr_replace function to insert a string into another by replacing a sub string of length 0 at the wanted position in the original.
The following is the arguments you should use to the substr_replace function if you want to insert one string into another string in PHP:
$newstring=substr_replace($orig_string, $insert_string, $position, 0);
Quite simple, no?
