View Full Version : remove number from string
06-21-2010, 11:04 PM
Let's say I've got a string like this:
which line do I need if I want to remove one of those numbers (inluding the comma behind it) for example 11?

This might help.
// initial string
// we explode at the comma to put them into an array
$arr = explode(",",$string);
// this is the value we want to find
$val = 11;
// we get the key of that value, this could fail if there is more than one key.
// I think it just returns the first one.
$key = array_search($val,$arr);
// we do a print_r to see the values in the array initially
// now we remove the part of the array that contained the value we found
// we need to reindex the array
$arr = array_values($arr);
// now we do a print_r again to print out the new array
// we can implode to create our string again.
$string = implode(",",$arr);
// we echo out our new string.
There might be an easier way but that is all I can think of right now.

Thanks for replying. That's a lot of code...
Hope someone knows a shorter version before I'm gonna implement

If the number is only showing up once and you know there will be a comma before it, you could use
str_replace(',11', '', $string);
You can also use regex.
You do realize a part of the code provided to you above could be removed... its used to display the array as is so you can see whats going on.
