為什么二維數(shù)組索引加關(guān)聯(lián)形式里面的鍵不能用方括號(hào)只能用雙引號(hào)？
為什么二維數(shù)組索引加關(guān)聯(lián)形式里面的鍵不能用方括號(hào)只能用雙引號(hào)？例如?$res=array (
[0]=>array("id" => "28" ,"username"=> "admin" ,"password" => "admin" ,"age" => "270"),
[1]=>array("id" => "29", "username" => "admin", "password" => "admin" ,"age" => "270"));
??$res=array (
"0"=>array("id" => "28" ,"username"=> "admin" ,"password" => "admin" ,"age" => "270"),
"1"=>array("id" => "29", "username" => "admin", "password" => "admin" ,"age" => "270"));上面執(zhí)行出來(lái)就是Parse error: syntax error, unexpected '[', expecting ')'
下面執(zhí)行出來(lái)就對(duì)的
