很多站长朋友们都不太清楚phpzip函数，今天小编就来给大家整理phpzip函数，希望对各位有所帮助，具体内容如下：
本文目录一览： 1、 php怎样实现对zip文件的加密和解密 2、 php如何压缩一个文件夹里面所有的文件到zip文件里面？ 3、 怎样用php压缩解压rar,zip文件? 4、 php 数组追加 5、 编译PHP提示zip错误，请问怎么解决 6、 为什么php创建zip文件不管用 php怎样实现对zip文件的加密和解密使用PHPZip类就可以解决的。以下是网上找到的例子。

php如何压缩一个文件夹里面所有的文件到zip文件里面？//函数:文件压缩
//压缩参数:需要压缩的文件或文件夹(文件可为数组),压缩后的zip文件名及存放路径,压缩类型1:文件夹2:文件,后续操作1:压缩后下载;2:存放在服务器上(默认为/@Upload下)
//压缩文件夹示例:Tozip("./","".date("d-H-i-s").".zip",1,2);
//压缩文件示例:
// $aaa=array("1.txt","2.txt");
// Tozip($aaa,"2.zip",2);FunctionTozip($Path,

怎样用php压缩解压rar,zip文件?要用PHP压缩解压文件，常用的方法是调用命令行去执行解压缩操作
可以用exec()
、system()等函数调用shell命令
Linux下解压缩命令是tar
[-cxtzjvfpPN]
文件与目录，tar命令可以压缩解压.tar、.gz、.tar.gz、.tgz、.bz2、.tar.bz2、.Z、.tar.Z、.zip这些类型的文件
Linux下默认无法使用rar格式的，要另外安装RAR
for
Linux，然后使用rar和unrar命令解压缩rar格式的压缩文件
php 数组追加在PHP里面，往数组中追加元素最简单的方法是使用[]赋值，例如需要在$arr添加一条123的语句是$arr[]=123，可以参考下面的代码：
<?php
$arr=[123,456];
print_r($arr);
$arr[]=789;
print_r($arr);
?>
扩展资料：
PHP函数
constant() 函数返回常量的值。
connection_status() 函数返回当前的连接状态。
connection_aborted() 函数检查是否断开客户机。
zip_read()() 函数读取打开的 zip 档案中的下一个文件。
zip_open() 函数打开 ZIP 文件以供读取。
zip_entry_read() 函数从打开的 zip 档案项目中获取内容。
zip_entry_open() 函数打开一个 ZIP 档案项目以供读取。

编译PHP提示zip错误，请问怎么解决vi /etc/ld.so.conf.d/local.conf //创建local.conf
/usr/local/lib //添加输入
ldconfig -v //执行命令
为什么php创建zip文件不管用请参考php手册,函数特点-压缩与归档扩展部分
下面是手册实例一:
<?php
$zip = new ZipArchive();
$filename = "./test112.zip";
if ($zip->open($filename, ZIPARCHIVE::CREATE)!==TRUE) {
exit("cannot open <$filename>\n");
}
$zip->addFromString("testfilephp.txt" . time(), "#1 This is a test string added as testfilephp.txt.\n");
$zip->addFromString("testfilephp2.txt" . time(), "#2 This is a test string added as testfilephp2.txt.\n");
$zip->addFile($thisdir . "/too.php","/testfromfile.php");
echo "numfiles: " . $zip->numFiles . "\n";
echo "status:" . $zip->status . "\n";
$zip->close();
?>
