merge values of the relative indexes

[omerbutt]

hi,
i need to merge the values of arrays in the follwoing manner ,

$a1=array('a','b','c');
$a2=array('1','2','3');

and after merging the 2 arrays the resultant array should look like this

array('a|1','b|2','c|3');

i have looked into array_merge() and array_combine() but they wont help in this case, does anybody knows a function that would work in this regard i donot want to iterate to each index with a loop as the arrays could be large and it would consume more time.
regards,
Omer Aslam.

There's no way around iterating through the array. If a function existed that did what you wanted to do, it would necessarily have to iterate through the array.
