Insert Text into a String

[random1]

Hi All,

 

Basic question: How can you insert text (in this case a space character) into a string?

 

For example: transform the credit card number - 0000000000000000

 

into 0000 0000 0000 0000

you could do it a few ways

<?php
$cc = "0000000000000000";
echo substr($cc, 0, 4)." ".substr($cc, 4, 4)." ".substr($cc, 8, 4)." ".substr($cc, 12, 4);
?>

 

<?php
$cc = "0000000000000000";
$cc = preg_replace('/(\d{4,4})/', '\1 ', $cc);
?>
