[Resolved] If Variable Is Present

[RxGx]

I want to write a PHP script that will search for a variable in the string. If it's not found I want the code to ignore the variable code.

<?php
// get string variable
if ((strlen($_GET['name']))>4) {
     $name = $_GET['name'];
     echo $name;
     echo "<br>";
}

//define the path as relative
$path = "/web/apache2/htdocs/intranet";

//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");
echo "Directory Listing of $path<BR>";

//running the while loop
while ($file = readdir($dir_handle)) {
        echo "<a href='file:///d:/$path/$file'>$file</a><br>";
}

//closing the directory
closedir($dir_handle);  

?>

I don't want to get errors if the "name=" isn't at the end of the filename.

if (!empty($_GET['name'])) {
     $name = $_GET['name'];
     echo $name;
     echo "<br>";
}
