PHP下载文件，读取问题

Question

<?php 
function saveFile($url, $filename) { 
    $data = file_get_contents($url); 
    $fh = fopen($filename, 'w') or die("can't open file"); 
    fwrite($fh, $data); 
    fclose($fh); 
} 
$myFile = "images.txt"; 
$fh = fopen($myFile, 'r'); 
$theData = fread($fh, filesize($myFile)); 
$data = explode("\n", $theData); 

$count = count($data); 

for($i=0;$i<=$count;$i++) { 

    saveFile($data[$i], basename($data[$i])); 
} 

?> 

这是我的代码我每次更换打印错误

Warning: fopen(10017226314.jpg) [function.fopen]: failed to open stream: Invalid argument in C:\xampp\htdocs\download\download.php on line 4 
can't open file 

应该是什么原因一个动态的文件名？请帮忙。由于

请更换您的fopen函数的参数从w到r+

function saveFile($url, $filename) { 
    $data = file_get_contents($url); 
    $fh = **fopen($filename, 'r+')** or die("can't open file"); 
    fwrite($fh, $data); 
    fclose($fh); 
}
