自 PHP 5.4 轉換為 PHP 7.0 的腳本

从PHP 5.5开始，mysql_connect等功能已不再可用，因此需要将它们转换为mysqli_connect。

#! /bin/bash
#
#   mysql_to_php7.sh
#
#                       May/30/2017
#
ls $1/*.php > /tmp/tmp01
awk '{print "sed -i -f sed_to_mysqli",$1}' /tmp/tmp01 > /tmp/go_tmp
#
bash /tmp/go_tmp
#

#
#   sed_to_mysqli
#
#               May/31/2017

使用方法

在文件夹中将有 *.php 文件被转换。
