今天安装Ecshop后，运行出现各种问题，其中 Deprecated: preg_replace() 之类的报错最多，下面贴出解决方案：
错误原因：
preg_replace() 函数中用到的修饰符 /e 在 PHP5.5.x 中已经被弃用了。
如果你的PHP版本恰好是PHP5.5.X，那你的ECSHOP肯定就会报类似下面这样的错误：
Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in......
解决办法：
1. Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in \includes\cls_template.php on line 300
原有内容：
return preg_replace("/{([^\}\{]*)}/e", "\$this->select('\\1');", $source);
修改后内容:
return preg_replace_callback("/{([^\}\{]*)}/", function($r) { return $this->select($r[1]); }, $source);
2. Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in \includes\cls_template.php on line 491
原有内容:
$out = "<?php " . '$k = ' . preg_replace("/(\'\\$[^,] )/e" , "stripslashes(trim('\\1','\''));", var_export($t, true)) . ";";
修改后内容:
$out = "<?php " . '$k = ' . preg_replace_callback("/(\'\\$[^,] )/" , function($match){return stripslashes(trim($match[1],'\''));}, var_export($t, true)) . ";"
3. Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in \includes\cls_template.php on line 550
原有内容:
$val = preg_replace("/\[([^\[\]]*)\]/eis", "'.'.str_replace('$','\$','\\1')", $val);
修改后内容:
$val = preg_replace_callback('/\[([^\[\]]*)\]/is',function ($matches) {return '.'.str_replace('$','\$',$matches[1]);},$val);
4. Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in \includes\cls_template.php on line 1074
原有内容:
$source = preg_replace($pattern, $replacement, $source);
修改后内容:
$source = preg_replace_callback($pattern, function ($matches) { return '{include file='.strtolower($matches[1]). '}';},$source);
5. Strict Standards: Only variables should be passed by reference in ...\upload\includes\lib_main.php on line 1329
原有内容：
$ext = end(explode('.', $tmp));
修改后内容：
$extsub = explode('.', $tmp);
$tmp = end($extsub);
$tmp = basename($tmp,".$ext");
最后，将错误修改后,上传到服务器.然后进入后台,清空缓存,刷新页面即可。
