removing part of the array

[MrAdam]

hey all!i've been on with this for past half hour, and im a bit frustrated now!i have a variable which contains an id. In some cases the id may be repeated (multiple times), and a comma inbetween the id's. for example: "33" OR "33,33" OR "33,33,33" etc.im trying to create a simple function to remove just one of the id's: so, "33,33" becomes "33".my question is; how do I do it ?! -Thanks!

http://www.php.net check out the function for array_unique()http://ca.php.net/manual/en/function.array-unique.php

[MrAdam]

thanks-but not quite what im looking for.

Explode the variable into an array and then use the array_unique () to reduce it down to a single occurence.An alternate would be to explode the variable into an array and use the array(0) element.

no no, thing is, i don't want the unique.. i want to get rid of just one of the identical id's .. so if the variable contained "33,33,33,33" .. i want to be left with "33,33,33".

i managed to sort it:

$id = "72"; // usually i would have run some statements to be left with the array[x] matching my id$test = Array();$test[0] = "72,72,72";$len = strlen($id) + 1; // length of ID plus 1 more for the comma$rem = strlen($test[0]) - $len; // the remainder from length of the array[x] minus $len$test[0] = substr($test[0],$len,$rem); // use substr() to only select after the first id, effectivelly, only removing one of the IDs
