thinkphp3.1 升 php7.1 指南

1、主要是把有e修饰符的preg_replace函数替换成preg_relpace_callback。因为php5.5之后已经弃用e修饰符了，推荐用preg_relpace_callback代替。

d、ThinkPHP/Lib/Template/TagLib.class.php 129行替换为

if(version_compare(PHP_VERSION,'7.0.0','<')){
$condition
=
preg_replace('/($Think.*?)s/ies',"$this->parseThinkVar('\1');" , $condition);
}else{
$condition
=
preg_replace_callback('/($Think.*?)s/is',function($matches){return $this->parseThinkVar($matches[1]);} , $condition);
}

a、ThinkPHP/Lib/Core/Dispatcher.class.php 第 132 行中替换为

// 解析剩余的URL参数
#preg_replace('@(w+)/([^/]+)@e', '$var['\1']=strip_tags('\2');', implode('/',$paths));
if(version_compare(PHP_VERSION,'7.0.0','<')){
preg_replace('@(w+)/([^/]+)@e', '$var['\1']=strip_tags('\2');', implode('/',$paths));
}else{
preg_replace_callback('@(w+)/([^/]+)@', function($match) use(&$var){ return $var[$match[1]]=strip_tags($match[2]);}, implode('/',$paths));
}

b、ThinkPHP/Lib/Core/Db.class.php 第 605 行中替换为

//将__TABLE_NAME__这样的字符串替换成正规的表名,并且带上前缀和后缀
//$joinStr = preg_replace("/__([A-Z_-]+)__/esU",C("DB_PREFIX")."strtolower('$1')",$joinStr);
$joinStr = preg_replace_callback("/__([A-Z_-]+)__/sU",function($match){return C("DB_PREFIX").strtolower($match[1]);},$joinStr);

c、ThinkPHP/Lib/Template/ThinkTemplate 修改如下，

2、TinkPHP/Extend/Library/ORG/Util/String.class.php文件名改成Strings.class.php,类名改成Strings，或者你认为适合的名字，因为php7

无效的类、接口以及 trait 命名 ¶
不能以下列名字来命名类、接口以及 trait：
bool
int
float
string
NULL
TRUE
FALSE

然后把TinkPHP/Extend/Library/ORG/Util/Image.class.php中的import('ORG.Util.String');替换为import('ORG.Util.Strings')，String::替换为Strings:: 。

3、使用mysqli替代mysql连接数据库
