If you are trying to find out if given two arrays' keys match recursively, you can use this
function:
<?php
function array_keys_match($arr1, $arr2)
{
$return = true;
foreach ($arr1 as $key => $value)
{
if (isset($arr2[$key]))
{
if (strtolower(gettype($arr1[$key])) == 'array')
{
$return = array_keys_match($arr1[$key], $arr2[$key]);
}
}
else
{
$return = false;
break;
}
}
return $return;
}
Example:
$arr1 = array(
'key1' => array(
'key1a' => 'some value'
),
'key2' => 'heyoo'
);
$arr2 = array(
'key1' => array(
'key1a' => 'some value'
),
'key2' => 'heyoo'
);
var_dump(array_keys_match($arr1, $arr2)); // returns bool(true)
$arr3 = array(
'key1' => array(
'key1a' => 'some value'
),
'key2' => array(
'key2a' => 'some value',
'key2b' => 'some value'
)
);
$arr4 = array(
'key1' => array(
'key1a' => 'some value'
),
'key2' => array(
'key2a' => 'some value',
'different_key' => 'some value'
)
);
var_dump(array_keys_match($arr3, $arr4)); // returns bool(false)
?>
