PHP implementation of sorting two-dimensional arrays by specified key names

This article gives an example of PHP Implementation of two-dimensional array by the specified key name sorting method . Share with you for your reference , As follows ：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

<?php /* The two-dimensional array is sorted by the specified key value */ functionarray_sort($array,$keys,$type='asc'){   if(!isset($array) || !is_array($array) || empty($array)){     return'';   }   // Sort field names , Such as ：id   if(!isset($keys) || trim($keys)==''){     return'';   }   // sort order , Such as ：desc、asc   if(!isset($type) || $type==''|| !in_array(strtolower($type),array('asc','desc'))){     return'';   }   // Define an array   $keysvalue=array();   foreach($arrayas$key=>$val){     // Filter sorting field values     $val[$keys] = str_replace('-','',$val[$keys]);     $val[$keys] = str_replace(' ','',$val[$keys]);     $val[$keys] = str_replace(':','',$val[$keys]);     // Put the key name specified in the record into the array , Such as ：[0]=>5,[1]=>3,[2]=>6     $keysvalue[] =$val[$keys];// Sort field , Such as ：id     Indexes =》 Sort key name   }   asort($keysvalue); // Sort by value in ascending order , And maintain the index relationship between key name and key value , Such as ：[1]=>3,[0]=>5,[2]=>6   reset($keysvalue); // The pointer points back to the first of the array   foreach($keysvalueas$key=>$vals) {     $keysort[] = $key;//0=>[1],1=>[0],2=>[2]   }   $keysvalue= array();   $count=count($keysort);// Number of sorting records   if(strtolower($type) != 'asc'){ // Descending     for($i=$count-1; $i>=0; $i--) {       $keysvalue[] = $array[$keysort[$i]];     }   }else{ // Ascending     for($i=0; $i<$count; $i++){       $keysvalue[] = $array[$keysort[$i]];     }   }   return$keysvalue; } $array=array(   array('name'=>'Tom','age'=>'23','like'=>'beer'),   array('name'=>'Trump','age'=>'50','like'=>'Food'),   array('name'=>'Jack','age'=>'26','like'=>'Travel') ); print_r(array_sort($array,'age')); ?>

Running results ：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

Array (   [0] => Array     (       [name] => Tom       [age] => 23       [like] => beer     )   [1] => Array     (       [name] => Jack       [age] => 26       [like] => Travel     )   [2] => Array     (       [name] => Trump       [age] => 50       [like] => Food     ) )
