如何获取到文件中返回的数组(如数据库连接配置数据)01 确定文件的位置.从启动目录名称定义为变量,替换反斜杠,开始拼接02 导入include不报错,赋值给数组 $config = @include(self::$_file); 有错误继续执行.并隐藏错误03 数组就得到了,文件中return返回的数据define('DS', '/');define('CMST

$arr = array(array("catid"=>"841","parentids"=>null,"childids"=>"842,843,943","name"=>"TV9","url"=>"http111"),array("catid"=>"853","parentids"=>null,"childids"=>"854,855,856","name"=>"APP-ad","url

遍历数组.重新命名,选择需要的下标和数据.可以遍历,放入新的数组中$arr = array(array("catid"=>"841","parentids"=>null,"childids"=>"842,843,943","name"=>"TV9","url"=>"http111"),array("catid"=>"853","parentids"=>null,"childids"

$parentid = '000000841';$parentid = substr($parentid, 0, 1) == 2 ? null : substr($parentid, 6);echo $parentid;减去开头6个0,不写截取多少位.默认从截取位置开始6.到最后

php 输出乱码,可以在文件头部 ,加入 header("content-type:text/html;charset=utf-8");html乱码mysql乱码
