Eliminate presence of String1 from String2

I have $String1 which I know has the value 999 and is 3 digits and starts at pos 7 in $String2.

$String1 = 999;  
$String2 = 789992399987;

I would like to eliminate $String1 from $String2, to create $String3

$String3 = 789992387;

I don't think I can use strstr, because as in this case 999 appears 0,1 or more times before the string I want to eliminate

My current work around is the unelegant way of making $String2 an array and because I know the position and length of $String1 unset those keys.

If you want to remove a substring from a string by position and length, you can use substr_replace.

$String3 = substr_replace($String2, '', 7, 3);
