I have a string:

buynaturallesunfloweroil1ltrat78rupees

now this string have two occurrences of at. I want to split the string atgetorlast occurrence of at.`

Some strings can be like buynaturallesunfloweroilget1ltrat78rupees

buynaturallesunfloweroil1ltrat78rupees.

I want to split the string such that:

Arr[0] = buynaturallesunfloweroil1ltr

Arr[1] = 78rupees

Basically I have to split the string at last occurence of at. I am not very good at preg_split.

Thanks in advance.

Try this:

(.*)at(.*)
  1. You get Arr[0] in group 1
  2. Arr1 in group 2

Explanation

Sample Code:

<?php

$re = '/(.*)at(.*)/s';
$str = 'buynaturallesunfloweroil1ltrat78rupees';

preg_match_all($re, $str, $matches);

// Print the entire match result
print_r($matches);

?>

and the reason is ?
preg_split("/(.*)at(.*)/", "buynaturallesunfloweroil1ltrat78rupees"); is giving me empty array.
what if I want only arr[0] and arr[1]. $matches give me actually array of size 3.
No, as it will break at each instance of 'at'
if you don't understand how regex thing work, then you need to know that, index zero contains the full match (full string) , and then comes the capture groups which is group 1 and 2

Try this :

<?php
 $str = "buynaturallesunfloweroil1ltrat78rupees";

echo $filename = substr($file, 0, strrpos($str, 'at')); echo '---';
echo $extension = substr($file, strrpos($str, 'at') + 2);

?>

Sorry for my above answer. it was not fully functional:

here find the answer : 

$str = "buynaturallesunfloweroil1ltrat78rupees";
echo $first = substr($str, 0, strrpos($str, 'at')); echo '---';
echo $second = substr($str, strrpos($str, 'at') + 2);
