Answer 1

Use php function array_diff(array1, array2);

It will return a the difference between arrays. If its empty then they're equal.

example:

$array1 = array(
    'a' => 'value1',

    'b' => 'value2',

    'c' => 'value3'
 );

$array2 = array(
    'a' => 'value1',

    'b' => 'value2',

    'c' => 'value4'
 );

$diff = array_diff(array1, array2);

var_dump($diff); 

//it will print array = (0 => ['c'] => 'value4' ) 

Example 2:

$array1 = array(
    'a' => 'value1',

    'b' => 'value2',

    'c' => 'value3',
 );

$array2 = array(
    'a' => 'value1',

    'b' => 'value2',

    'c' => 'value3',
 );

$diff = array_diff(array1, array2);

var_dump($diff); 

//it will print empty;
