Insert string into String based on number of chars

[zfred09]

Say I had

 

$string = "I swear I have seen this before.";

 

I want to add

 

$addme = "**";

 

into the original string after 10 characters.  How would I do this?

Just need to use substr():

 

<?php 
$string = "I swear I have seen this before.";
$addme = '**';
$add_after = '10';
$new_string = substr($string,0,$add_after).$addme.substr($string,$add_after);
echo $new_string;
?>

Ok, that seems to work. Thanks.
