SUGGESTION to the PhP Group 
(I did not find any place for suggestions on the site:
the suggestion links seem to point here)

How about a  SUBSTR_ADD  function similar to substr_replace

substr_add (mixed string, string replacement, int start [, int length] )

example when handling time (in schedules etc)

$var=1245
$var= substr_add ($var, ':', 2);
                  $var value now 12:45

Yes-- you can split and add and rejoin strings, or probably use preg_replace, but I am surprised that such a simple useful facility does not seem to be available in PHP !  :-(          Thanks!  Peter Douglas

Expected result:

N/A

( SUBTRACTION, on the other hand, does work simply enough with the current system:
with SUBSTR_REPLACE being able to replace a character with an empty string "" )

substr_replace() already provides this when the length argument is 0.

Closing this, as it can be easily done with substr_replace() already:

    $var = substr_replace($var, ':', 2, 0);

Doesn't make much sense to add an extra function for this.
