Question

PHP中foreach嵌套循环输出数组代码？

Answer 1

以下是编写json数据转换成数组时写foreach嵌套循环输出的代码：

<?php
$json = '[{"a":1,"b":2,"c":3,"d":4,"e":5},{"a":12,"b":22,"c":32,"d":42,"e":52},{"a":13,"b":23,"c":33,"d":43,"e":53}]';
$arr = (array) json_decode($json,true);
foreach($arr as $arrvalue)
{
foreach($arrvalue as $key=>$value)
{
echo "[$key] = $value <br />";
}
}
?>

Answer 2

foreach($arr as $key =>$value){
echo $value //$value是值
echo $key //$key是键值
}
楼下哥们弄错了

Answer 3

foreach($arr $key->$value){
echo $value

}
