Manipulate String, Insert Characters

[JustinK101]

What is the best way to do the following string manipulation.

 

$string = "012354631556"

 

I want to add brackets after the last character, and then before the 6th to last character. So:

 

$string = "012354[631556]"

 

What is the best way to do this? Thanks.

One way would be to use the substr function:

<?php
$string = '012354631556';
$rem_len = (strlen($string) - 6) * -1;
$new_str = substr($string,0,6) . '[' . substr($string,$rem_len) . ']';
echo $new_str;
?>

Ken,

 

Thanks for the code, but that code assumes the string is always fixed length, it is not. For example it needs to work with:

 

$string = "24743734"

 

Into

 

$string = "24[743734]"

Perhaps...

 

$string = "0123456789876543210";
$new_string = substr($string, 0, -6) . "[" . substr($string, -6) . "]";

Sorry, I mis-read the requirements.

you should check that the length of the string is atleast 7 characters or it might throw an error

[litebearer]

example using various lengths...
