Array in PHP
$arrdata = $array(
'1'=>'foo',
'2'=>'bar',
'3'=>'baz');
$arrval = array_values($arrdata); // gives ['foo','bar','baz']
$arrkey = array_keys($arrdata); // gives ['1','2','3']
$array_push($arrval,'bat'); // insert 'bat'
$array_pop($arrval,'bat'); // remove 'bat'
$a = $arraydata['1'];
Compare and check if two array conatins are identical
array1 = ['a', 'b','c'];
array2 = ['a1', 'b2' , 'c3' ];
if( array1.toString() == array2.toString() ){
//identical
}else{
// non identical
}
