背景
針對PHP導出Excel的優化,在我之前的一篇文章裡已經做過介紹:關於PHP記憶體溢出的思考,本文主要介紹一款高性能的導出組件–xlswriter,他是一個PHP C擴展,官方文檔地址,請點擊。

安裝
安裝pecl
##當我們發現pecl未安裝時,則需要安裝pecl。一般情況下,是安裝在PHP的安裝目錄,範例指令如下:
# 进入PHP安装目录 cd /usr/local/php/bin curl -o go-pear.php http://pear.php.net/go-pear.phar php go-pear.php # 安装完成后,软连接到bin目录下 ln -s /usr/local/php/bin/pecl /usr/bin/pecl
安裝xlswriter
pecl install xlswriter # 添加 extension = xlswriter.so 到 ini 配置
使用
############################### #具體使用可以參考官方文檔,會介紹的更加詳細,我這就上一段我使用中的代碼:######封裝的導出service###
