Use values that are in all arrays and skip the rest - php

Question

I have an array with 3 sub arrays like:
$array = array(
width => array(
0 => 1,
1 => 2,
2 => 3,
3 => 4,
4 => 5
),
height => array(
0 => 1,
1 => 2,
2 => 7,
3 => 8
),
color => array(
0 => 2,
1 => 7,
2 => 8
)
);
The count is in this case 3 as I have 3 arrays. This can be sometimes more or less, that's why I have a count.
Now I want to find out which number is in all 3 arrays and only use those. in above example the only returned number should be 2 as it's present in all 3 sub arrays.
I was trying something like below, but am really stuck what's the best approach...
$i = count($array); // gives me back the count of 3 which is correct
$n = 0;
foreach($array as $key=>values) {
foreach($values as $value) {
// do not how to proceed :(
}
}

Answer 1

You can call array_intersect with all the sub-arrays as arguments.
$common_values = call_user_func_array('array_intersect', $array);

Answer 2

Maybe you can affect your rows in some var and make what you want to do in your foreach
Like :
<?php
$width = 0;
$height = 0;
$color = 0 ;
$arrayBundleWidth = array();
$arrayBundleHeight = array();
$arrayBundleColor = array();
foreach ($array as $arrayRow){
$arrayBundleWidth = $arrayRow['width'];
$arrayBundleColor = $arrayRow['color'];
$arrayBundleHeight = $arrayRow['height'];
foreach ($arrayBundleWidth as $arrayBundleWidthtRow) {
# code...
#you got each index of your width array here
}
foreach ($arrayBundleHeight as $arrayBundleHeightRow) {
# code...
#you got each index of your height array here
}
foreach ($arrayBundleColor as $arrayBundleColorRow) {
# code...
#you got each index of your color array here
}
}
?>
Try it and tell me ? Is it what you want ?
Not sure if it's what you wanted to do !
