数组的使用

$dirfile = file( "dir.txt" );
$dirlist = array();
$namelist = array();
foreach($dirfile as $key=>$value){
    $wordStr = explode('>',$value);//分割字符串
    array_push($dirlist, $wordStr[0]);//添加数据
    array_push($namelist, $wordStr[1]);
}  
$dirlistArr = array();//二维数组
$dirlistArr[0] = $dirlist;
$dirlistArr[1] = $namelist;

 查找

 array_search("查找的字符串","内容"); //返回数组索引
