问题:
有数组: 代码如下:array(0=>array('id'=>1,'price'=>50),1=>array('id'=>2,'price'=>60));
要求根据数组的price这个字段进行排序。
实现代码如下:
<?php $array[] = array('id'=>1,'price'=>50); $array[] = array('id'=>2,'price'=>70); $array[] = array('id'=>3,'price'=>30); $array[] = array('id'=>4,'price'=>20); foreach ($array as $key=>$value){ $id[$key] = $value['id']; $price[$key] = $value['price']; } array_multisort($price,SORT_NUMERIC,SORT_DESC,$id,SORT_STRING,SORT_ASC,$array); echo ''; print_r($array); echo ''; ?>
运行结果:
Array ( [0] => Array ( [id] => 2 [price] => 70 ) [1] => Array ( [id] => 1 [price] => 50 ) [2] => Array ( [id] => 3 [price] => 30 ) [3] => Array ( [id] => 4 [price] => 20 ) )
希望本文所述对大家PHP程序设计有所帮助。
