如何在PHP中搜索部分数组值

Question

First of all - thx for ansvers.

I have got 2 arrays:

For example:

['a' => abc, 'b' => cde]

And second one

['fcb' => cde, 'avm' => efg]

Need to have true of 'b' and 'cde'.

How get a certain similarity for this?

I may be falling into a trap; but, you can compute the intersection (common values) and loop them and search for the key:

$result = array_intersect($array1, $array2);

foreach($result as $val) {
    echo "$val found in array1 at key: " . array_search($val, $array1)."<br>
";
    echo "$val found in array2 at key: " . array_search($val, $array2)."<br>
";
}

See Example.
