php多维数组排序与操作函数
PHP多维数组排序与操作函数,代码如下:
function arraycd( $arr ){ static $res_arr = array (); if ( is_array ( $arr )) { foreach ( $arr as $key => $val ) { if ( is_array ( $val )) { arraycd( $val ); } else { $res_arr []= $val ; } } } elseif ( is_string ( $arr )) { $res_arr []= $arr ; } return implode( "," , $res_arr ); }? $fruits = array ( "fruits" => array ( "a" => "orange" , "b" => "banana" , "c" => "apple" ), "numbers" => array (1, 2, 3, 4, 5, 6), "holes" => array ( "first" , 5 => "second" , "third" ) ); $strayy =arraycd( $fruits ); var_dump( $strayy );看一个多维数组排序,代码如下:
function sortdata( $data , $col , $order ){ if ( count ( $data )) $temp_array [key( $data )] = array_shift ( $data ); foreach ( $data as $key => $val ){ $offset = 0; $found = false; foreach ( $temp_array as $tmp_key => $tmp_val ){ if (! $found and strtolower ( $val [ $col ]) > strtolower ( $tmp_val [ $col ])){ $temp_array = array_merge (( array ) array_slice ( $temp_array ,0, $offset ), array ( $key => $val ), array_slice ( $temp_array , $offset ) ); $found = true; } $offset ++; } if (! $found ) { $temp_array = array_merge ( $temp_array , array ( $key => $val )); } } if ( strtolower ( $order )== "asc" ){ $array = array_reverse ( $temp_array ); } else { $array = $temp_array ; } return $array ; } 主函数 $data = array ( array ( 'name' => 'alice' , 'key' => '2fc4ab3d639e5400efdfc73bc27e83f1' , 'age' =>20 ), array ( 'name' => 'claudia' , 'key' => '831c2b79c1f19af39c7e3321e11e5f5e' , 'age' =>18 ), array ( 'name' => 'beatrice' , 'key' => '6f8512a2066b8f35a27a495ce1228c76' , 'age' =>100 ), array ( 'name' => 'denise' , 'age' =>25, 'key' => 'ef6de3b178bf9f69a9fef72e4ee7bbe9' ) ); $arr1 = sortdata( $data , "name" , "asc" ); echo "<pre>" ; var_dump( $arr1 ); echo "</pre>" ; $arr2 = sortdata( $data , "age" , "desc" ); echo "<pre>" ; var_dump( $arr2 ); echo "</pre>" ;查看更多关于php多维数组排序与操作函数 - php数组的详细内容...
