$dir = DirName (__file__); The folder where the current file is located, with the directory name to traverse
$dir = ' D:\PHP\wamp\www\admin\hosts\admin ';
PHP iterates through all the files in the folder
$handle =opendir ($dir. ".");
$arr = Array ();
while ($file =readdir ($handle)) {
if (Is_file ($file)) {
if ($file! = "." && $file! = "...") {
$file = Mb_substr ($file, 0,strripos ($file, '. '));
$files = Explode (' ', $file); Convert $file to an array
$arr []= $files [' 0 '];//into a one-dimensional array
}
}
}
Print_r ($arr);
Closedir ($handle);
PHP gets the value of Input->name
foreach ($_post as $key = = $value) {
if (!in_array ($key, $arr)) {//Determine the name value is not in $arr
echo "$key: not Present";
}
}
?>
Test
The above describes the PHP traversal folder under the file and get to the value of input name, including the aspects of the content, I hope to be interested in PHP tutorial friends helpful.
