php对角线数组代码,php数组内容查找代码
Array
(
[0] => Array
(
[id] => 6
[title] => 鳳凰
[bid] => 2
)
[1] => Array
(
[id] => 5
[title] => 年康
[bid] => 2
)
[2] => Array
(
[id] => 4
[title] => 海鷗
[bid] => 2
)
[3] => Array
(
[id] => 3
[title] => 111cn.net
[bid] => 1
)
[4] => Array
(
[id] => 2
[title] => 中國WEB第一站
[bid] => 1
)
[5] => Array
(
[id] => 1
[title] => www.111cn.net
[bid] => 1
)
)
//方法一,直接把值取出來，并且輸出
foreach($arr as $key=>$val){
foreach($val as $k=>$val2){
if($val2['bid']==1){//判斷
echo $val2['bid']."
";
}
}
}
//方法二，把符合條件的數(shù)組再次生成數(shù)組
代碼如下
復(fù)制代碼
res=array();
foreach($arr as $sub){
foreach($sub as $value){
if($value==1){
array_push($res,$sub);
}
}
}
print_r($res);
//結(jié)果為
