Finding matched keywords in a exploded string.

Hello,

I have a large chunk of data that i’m using the below code to explode using an array of keywords, basically the data i have is sections which i need to split up, but there are potentially more than 3 sections in some cases.

[code=php]
$string = “start time 00:30 mid time 00:45 end time 01:00”
$delim = array(‘start’, ‘mid’, ‘end’);
$step_01 = str_replace($delim, ‘+delim+’, $string); //Extra step to create a uniform value
$exploded_string = explode(‘+delim+’, $step_01);

print_r($exploded_string);
//prints out
//[0]=> time 00:30 [1]=> time 00:45 [2]=> time 01:00
[/code]

If there is four sections, it will print out this
//[0]=> time 00:30 [1]=> time 00:45 [2]=> time 01:00 [3]=> time 02:00

What i need to know, is there a way of finding out the matched keyword from the array to each section, e.g [2] = “End”

Or possibly when a match is found, making a new array matching keywords to array parts?

I’m a bit stuck on this! any help is much appreciated.
