Question

php 怎么随机抽取二维数组里的几个数组？？？

例如：
$data = array(
array(
"price" => "6874","air" => "国泰"
),
array(
"price" => "4726","air" => "大韩航空"
)
array(
"price" => "6569","air" => "国泰航空"
),
array(
"price" => "6569","air" => "卡塔尔航空"
),
array(
"price" => "3380","air" => "美国航空"
),
array(
"price" => "4200","air" => "泰国航空"
)
);
怎么取得其中的几组数组？？？

Answer 1

//你的数组少写了个逗号
$data = array(
			array(
				"price" => "6874","air" => "国泰"
			),
			array(
				"price" => "4726","air" => "大韩航空"
			),
			array(
				"price" => "6569","air" => "国泰航空"
			),
			array(
				"price" => "6569","air" => "卡塔尔航空"
			),
			array(
				"price" => "3380","air" => "美国航空"
			),
			array(
				"price" => "4200","air" => "泰国航空"
			)
	);
//随机选择出两个元素
$temp=array_rand($data,2);
//重组数组
foreach($temp as $val){
	$data_last[]=$data[$val];
}
print_R($data_last);

Answer 2

//你的数组少写了个逗号$data = array( array( "price" => "6874","air" => "国泰" ), array( "price" => "4726","air" => "大韩航空" ), array( "price" => "6569","air" => "国泰航空" ), array( "price" => "6569","air" => "卡塔尔航空" ), array( "price" => "3380","air" => "美国航空" ), array( "price" => "4200","air" => "泰国航空" ) );//随机选择出两个元素$temp=array_rand($data,2);//重组数组foreach($temp as $val){ $data_last[]=$data[$val];}print_R($data_last);

Answer 3

array_rand($data,$numbers);
望采纳
看错了 不明白你是要随机取吗？
还是取固定的？
