Read only pdf files and get the filename of that pdf files in a directory
<p>I need to read only pdf files in a directory and then read the filename of every files then I will use the filename to rename some txt files. I have tried using only eregi function. but it seems cannot read all I need. how to read them well?
here's my code :</p>

<pre><code>$savePath   ='D:/dir/';
$dir       = opendir($savePath);
$filename  = array();

while ($filename = readdir($dir)) {
if (eregi("\.pdf",$filename)){
    $read = strtok ($filename,"."); //get the filenames

//to rename some txt files using the filenames that I get before
//$testfile is text files that I've read before
    $testfile = "$read.txt";
    $file = fopen($testfile,"r") or die ('cannot open file');

    if (filesize($testfile)==0){} 
    else{
        $text = fread($file,55024);
        fclose($file);
        echo "&lt;/br&gt;"; echo "&lt;/br&gt;";         
    }
}
</code></pre>
