好吧,这个小问题快把我逼疯了。
这是 $strap_materials 的 print_r 输出:
Array(
[0] => steel
[1] => leather
[2] => polyester
[3] => leather
[4] => steel
)
我想计算每个值存在多少次并将每个总和放入数组中的数组中,就像这样:
Array(
[0] => Array(
"name" => steel
"count" => 2
)
[1] => Array(
"name" => leather
"count" => 2
)
[0] => Array(
"name" => polyester
"count" => 1
)
)
我的意图是像这样使用新创建的数组:
foreach($straps as $strap) {
echo "Name: " . $strap->name;
echo "Count: " . $strap->count;
}
我怎样才能做到这一点?
