note 81902 added to language.types.array

Sorting double dimensional arrays by a specified key bothe for Strings and for integers: Ex: $personDetails = array( array("firstName" => "Nancy", "lastName" => "Grace", "age" => 22), array("firstName" => "Andy", "lastName" => "Peter", "age" => 28), array("firstName" => "Jim", "lastName" => "Gary", "age" => 25), array("firstName" => "Lary", "lastName" => "James", "age" => 28), array("firstName" => "Peter", "lastName" => "David", "age" => 17), array("firstName" => "Raj", "lastName" => "King", "age" => 9), array("firstName" => "John", "lastName" => "Baxter","age" => 35) ); //To sort the array by firstName:- function sortFirstName($p1, $p2) { return strnatcmp($p1['firstName'], $p2['firstName']); } usort($personDetails, 'sortFirstName'); //To sort by an integer Field function sortByInteger(&$personDetails, $field) { $sort = "return strnatcmp(\$p1['$field'], \$p2['$field']);"; usort($personDetails, create_function('$p1,$p2', $sort)); return $personDetails; } $personDetails = sortByInteger($personDetails, 'age'); //To sort the array in Descending order by a key, It can be done by adding "-" sign before strnatcmp() function.
