Looping through 2 matching arrays in PHP

Question

I have 2 arrays, they are the same size, and each element corresponds to the same item in each array, ie, arrays look like

array1 => 'name', 'description', 'value' array2 => 'fred', 'manager', '100000'

So its basically a 2D array but they are separate due to the way they are built.

How do I iterate through them together so that I can join them like

name=fred, description=manager,

all in the same loop ?

EDIT Just realised i may have 3 arrays, array1, array2, array3, I assume that eliminates array_combine as an option ?

You can still do that see: stackoverflow.com/questions/6553752/… but I do think other methods are easier — Mramaa

for($x=0;$x<count($array1);$x++) { $element1 = $array1[$x]; $element2 = $array2[$x]; //Now you can use these elements }

or use array_combine()

$array3 = array_combine($array1,$array2); for($x-0;$x<count($array3);$x++){ $element2 = $array3[$x]; $element1 = key($array[$x]); }

or

$array3 = array_combine($array1,$array2); foreach ($array3 as $element1 => $element2){ //Do what you want }

What you prefer find/easiest...

I suggest you to use array_combine PHP function.

$array3 = array_combine($array1,$array2);
