Compare 2 array values in 2 arrays Php

Question

I have deleted the old post to make this more clear. I have 2 arrays that I need to compare and match but only if 2 values per array are the same.

$array1 = $plugins
$array2 = $xml_dump

A sample of what both arrays look like:

I need it to return the value ( or return true) only if $array1 Name , Version matches $array2 name ,ex_version

In the example above you can see that

$array1
Name => Ajax Category Dropdown
Version => 0.1.5

///has a match in 

$array2
name => Ajax Category Dropdown
ex_version => 0.1.5

I have tried many variations of array_intersect but I cannot get it to match 2 values for each array.

Yes it was way to cryptic, I completely changed it so hopefully it is more clear. — Wyck

If I understood you right this should do it:

array_intersect_assoc(array_intersect($global_plugins, $xml_plugins), array_intersect($plugin_verso, $xml_plugin_version));

Your question is very confusing, you are talking about $array1 and $array2 but I see four of them!

Anyway, have you tried the following? This is just a wild guess, but...

$result = array_intersect($global_plugins, $xml_plugins, $xml_plugin_version, $plugin_verso);

If this doesn't work, I suggest you drop your real world arrays and create some simple / small dummy ones instead and provide us with the result you want to archive for the very same dummy data.

Something like this, but this returns 0 even though both array_intersect work on their own and return a value.

@Wyck: Perhaps you need to use array_intersect() instead of array_intersect_assoc()?

@Wyck: It would be very helpful if you could share a sample of your array contents and the expected output.

I tried just array_intersect() no dice, I added a dump of the array to OP.

Yes writing this all out helped lol, I think I might make a function and use array_uintersect

<?php
$array1 = array("a" => "green", "red", "blue");
$array2 = array("b" => "green", "yellow", "red");
$result = array_intersect($array1, $array2);
print_r($result);
?> 
The above example will output:

Array
(
    [a] => green
    [0] => red
)

Just wanted to close this with what ended up being my solution.

I grab the Name and Version for both arrays and created a new array for each one, that way I could easily use array_intersect and manipulate they arrays. So to get this to work I just needed to create two new arrays with the values I wanted to compare.

 $a = array();
 $b = array();

 //first foreach loop

 $find_local_plugs = $global_plugins_name . $plugin_version;
 $a[] = $find_local_plugs;

 //second foreach loop

 $find_remote_plugs = $xml_plugins . $xml_plugin_version;
 $b[] = $find_remote_plugs;


 $matches = array_intersect($a, $b);
