PHP foreach multiple arrays - php

Question

Hi there I have been at a loss with the foreach loop. What I'm trying to do is have multiple arrays in a foreach loop.
All I can find on the Internet is how to get a single value out of the arrays. I managed to get two working with:
foreach (array_combine($slides, $headers) as $slide => $header)
But that's limited to only two arrays. I just want list after list for more than two arrays.

Since array_combine is working for you with two arrays, that means you want the elements at the same position, so you can use the same key:
foreach ($slides as $key => $slide) {
echo $slide;
echo $headers[$key];
echo $another[$key];
//etc...
}
If the keys may not match then re-index before the loop:
$slides = array_values($slides);
$headers = array_values($headers);
$another = array_values($another);
You will run into issues if the arrays aren't the same length so you might check:
if(isset($headers[$key])) { echo $headers[$key]; }
Another way might be to map them into a multi-dimensional array grouped one from each in a sub-array. The integer index for $values matches the order of the arrays in array_map:
foreach(array_map(null, $slides, $headers, $another) as $values) {
echo $values[0];
echo $values[1];
echo $values[2];
}
Or assign the array values to variables:
foreach(array_map(null, $slides, $headers, $another) as $values) {
list($s, $h, $a) = $values;
echo $s;
echo $h;
echo $a;
}
