Find last occurance of string

minimitt

Is it possible to find the last occurance of a string in a string and replace it with a string? For instance I have a string with tags withing the string. I would like to find the last occurance of and replace it with a blank. (eg: This is my test string This is a test string this is a test string )
I would like to take the last and remove it completely.

Possible?
TIA

1) Explode the whole thing into an array via some suitable marker (don't use the as the marker). So let's say the marker is the word 'break'

$array = explode("break", $string);

2) After that, count how many keys (sections) the array has.

3) Determine the last key and assign it to a string, i.e, $string2

4) Strip any tags from it via the eregi_replace function, i.e.

eregi_replace(" ", " ", "$string2");

5) Replace the array's last key with the new value of $string2 via...

$array["last key"] = "$string2";

That statement says: 'find any 's replace them with a space in the $string string.'

Alternatively if you know the tag is the last part of the string you can just strip it via a substring i.e.

$newstring = substr($string, 0, -4);
//since the is 4 characters long

Hope this helps.
