请问PHP使用foreach循环如何才能数组数组中的元素？
<?php
$area = [
["name" => "sh", "district" => "上海", "nums" => 0],
["name" => "hz", "district" => "杭州", "nums" => 1]
];
foreach ($area as $row) {
if ($row['nums'] == 0) {
unset($row);
}
}
print_r($area);网友回复
要改成as的形式
<?php
$area = [
["name" => "sh", "district" => "上海", "nums" => 0],
["name" => "hz", "district" => "杭州", "nums" => 1]
];
foreach ($area as $i=>$row) {
if ($row['nums'] == 0) {
unset($area[$i]);
}
}
print_r($area);
