I want to get the value form associative array . Array is

$abc=array(10) { 
  [0]=> array(2) { [0]=> string(7) "/?p=135" [1]=> string(1) "6" } 
  [1]=> array(2) { [0]=> string(6) "/?p=81" [1]=> string(1) "6" } 
  [2]=> array(2) { [0]=> string(7) "/?p=143" [1]=> string(1) "4" } 
  [3]=> array(2) { [0]=> string(7) "/?p=124" [1]=> string(1) "2" } 
  [4]=> array(2) { [0]=> string(6) "/?p=21" [1]=> string(1) "2" } 
  [5]=> array(2) { [0]=> string(6) "/?p=54" [1]=> string(1) "2" } 
  [6]=> array(2) { [0]=> string(6) "/?p=58" [1]=> string(1) "2" } 
  [7]=> array(2) { [0]=> string(6) "/?p=27" [1]=> string(1) "1" }

And The value that I want is [1]'s value that [0]'s value is "/?p=35" from $abc. How can I get ? Thankyou.

PHP >= 5.5.0:

$value = $abc[array_search('/?p=35', array_column($abc, 0))][1];

PHP < 5.5.0 use this in place of array_column:

array_map(function($v) { return $v[0]; }, $abc)
