ZipImg 一个PHP图片压缩利器
==================

[](#zipimg-一个php图片压缩利器)

### 安装

[](#安装)

```
composer require bingher/zipimg

```

### 使用

[](#使用)

```
$input = 'path-of-image';
$zipimg = new \bingher\zipimg\Image();
$zipimg->zip($input);

# 助手函数
zipimg($input);

```

### 注意事项

[](#注意事项)

- `php.ini`需要开启`shell_exec`函数
- windows环境 已经内置了压缩用的exe程序(32位),理论上直接用就行
- linux环境 需要编译安装`pngguant`,`guetzli`,`mozjpeg`

    - [安装pngguant](https://pngquant.org/install.html)

    ```
    # centos
    # libpng >= 1.6
    yum install libpng-devel
    git clone --recursive https://github.com/kornelski/pngquant.git
    cd pngquant
    ./configure --prefix=/usr/local/pngquant
    make && make install
    ln -s /usr/local/pngquant/bin/pngquant /usr/local/bin/pngquant

    ```

    - [安装guetzli](https://github.com/google/guetzli)

    ```
    #centos
    yum install libpng-devel
    yum install gcc gcc-c++
    mkdir guetzli && cd guetzli
    wget https://github.com/google/guetzli/archive/v1.0.1.tar.gz
    tar -zxvf v1.0.1.tar.gz
    cd guetzli-1.0.1
    make && make install
    ln -s 安装目录/bin/Release/guetzli /usr/local/bin/guetzli

    ```

    - 安装mozjpeg [官方教程](https://github.com/mozilla/mozjpeg/blob/master/BUILDING.txt)[参考教程](https://blog.liuguofeng.com/p/4644)

    ```
    # centos 7
    yum -y install build-essential nasm

    # centos 8 安装nasm
    # 到https://www.nasm.us/pub/nasm/releasebuilds下载相关rpm包
    wget https://www.nasm.us/pub/nasm/releasebuilds/2.15/linux/nasm-2.15-0.fc31.x86_64.rpm
    yum localinstall nasm-2.15-0.fc31.x86_64.rpm

    cd ~
    wget -O "mozjpeg-3.3.1.tar.gz" https://github.com/mozilla/mozjpeg/archive/v3.3.1.tar.gz
    tar -zxvf mozjpeg-v3.3.1.tar.gz
    cd mozjpeg-3.3.1
    autoreconf -fiv
    ./configure --prefix=/usr/local/mozjpeg
    make && make install
    ln -s /usr/local/mozjpeg/bin/cjpeg /usr/local/bin/cjpeg

    ```

### python服务

[](#python服务)

#### 1. php客户端远程调用python服务端进行图片压缩

[](#1-php客户端远程调用python服务端进行图片压缩)

> 由于生产环境php一般会禁用执行命令行等危险函数,可以考虑用开启python服务端,然后php进行调用实现图片压缩

- 进入`vendor/bingher/zipimg/python`目录
- 安装python库

```
pip install -r requirement.txt

```

- 开启服务

```
python zipimg_server.py

```

- 远程调用

```
