压缩上传文件的代码无法删除临时文件
伙计们,我正在编写代码来上传文件、压缩文件并删除 tmp 文件。 但是当我使用unlink功能时,它不会删除所有文件,有人可以向我解释为什么吗?
关注的php代码:
$zip = new ZipArchive();
$target_path = 'img/products/';
$zip->open($target_path.$id_insert.'.zip', ZIPARCHIVE::CREATE);
$img_count = $_POST['count_file'];
for ($i = 1; $i <= $img_count; $i++){
$temp = 'img'.$i;
$file = $i.'-'.$id_insert.'-'.$_FILES[$temp]['name'];
$path = $target_path.basename($file);
if(move_uploaded_file($_FILES[$temp]['tmp_name'], $path)) {
$zip->addFile($path, basename($file));
$files_to_delete[] = $path;
}
}
$zip->close();
foreach($files_to_delete AS $file){
//unlink(dirname(__FILE__).'/'.$path);
}
I guys, i'm writting code to upload file, zip them and delete tmp file.
But when i use unlink function, it do not remove all file, someone can explain to me why ?
Concerned php code :
$zip = new ZipArchive();
$target_path = 'img/products/';
$zip->open($target_path.$id_insert.'.zip', ZIPARCHIVE::CREATE);
$img_count = $_POST['count_file'];
for ($i = 1; $i <= $img_count; $i++){
$temp = 'img'.$i;
$file = $i.'-'.$id_insert.'-'.$_FILES[$temp]['name'];
$path = $target_path.basename($file);
if(move_uploaded_file($_FILES[$temp]['tmp_name'], $path)) {
$zip->addFile($path, basename($file));
$files_to_delete[] = $path;
}
}
$zip->close();
foreach($files_to_delete AS $file){
//unlink(dirname(__FILE__).'/'.$path);
}

在此块中,您应该将 $path 替换为 $file,因为这就是您要查找的内容。您会收到错误,因为第一次取消链接 $path 后,$path 处的文件被取消链接,但它的每个其他迭代都会尝试删除同一文件(这是分配给 $path 变量的最后一个文件)。
In this block you should replace $path with $file since that's what you're foreaching them as. You get the error because after you unlink $path the first time, the file at $path is unlinked, but every other iteration of it tries to delete the same file (which is the last one assigned to the $path variable).
