以下功能效果很好,但它只会压缩1个文件夹。我需要在网站的根目录中压缩几个特定的文件夹,但不是所有其他文件夹。

function Zip($source, $destination)
{
if (!extension_loaded('zip') || !file_exists($source)) {
return false;
}
$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
return false;
}
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file)
{
$file = str_replace('\\', '/', realpath($file));
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
else if (is_file($source) === true)
{
$zip->addFromString(basename($source), file_get_contents($source));
}
return $zip->close();
用这个打电话:
Zip('/folder/to/compress/', './compressed.zip');

如果我理解正确,您只需更改代码即可将$ source设置为字符串或数组。然后,您可以遍历该数组并添加所有所需的文件夹及其子文件夹
示例:
function Zip($source, $destination)
{
if (is_string($source)) $source_arr = array($source); // convert it to array
if (!extension_loaded('zip')) {
return false;
}
$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
return false;
}
foreach ($source_arr as $source)
{
if (!file_exists($source)) continue;
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file)
{
$file = str_replace('\\', '/', realpath($file));
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
else if (is_file($source) === true)
{
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
Zip可能为空,但所有指定的路径都无效,但您也可以处理它。
