ECSHOP如何解决Deprecated: preg_replace()报错

类似这样的报错：

( ! ) Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in E:\group1\includes\cls_template.php on line 551

Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in D:\wyh\ecshop\includes\cls_template.php on line 300

1、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肯定就会报类似这样的错误。

2、解决办法：

一、将 cls_template.php的300行

return preg_replace("/{([^\}\{\n]*)}/e","\$this->select('\\1');", $source);

换成：

return preg_replace_callback("/{([^\}\{\n]*)}/",function($r) {return $this->select($r[1]); },$source);

二、将cls_template.php的493行

$out = "<?php \n" .'$k = ' . preg_replace("/(\'\\$[^,]+)/e" ,"stripslashes(trim('\\1','\''));", var_export($t, true)) .";\n";

换成：

$out = <?php \n" . '$k = ' . preg_replace_callback("/(\'\\$[^,]+)/" , function($r) {return stripslashes(trim($r[1],'\''));}, var_export($t, true)) . ";\n";

三、将cls_template.php的552行

$val = preg_replace("/\[([^\[\]]*)\]/eis","'.'.str_replace('$','\$','\\1')",$val);

换成：

$val = preg_replace_callback("/\[([^\[\]]*)\]/",function($r) {return '.'.str_replace('$','$',$r[1]);},$val);

四、将cls_template.php的1069行

$pattern = '/<!--\s#BeginLibraryItem\s\"\/(.*?)\"\s-->.*?<!--\s#EndLibraryItem\s-->/se';
$replacement ="'{include file='.strtolower('\\1'). '}'";
$source = preg_replace($pattern,$replacement,$source);

换成：

$pattern = '/.*?/s';

$source = preg_replace_callback( $pattern , function ( $r ){ return '{include file=' . strtolower ( $r [1]). '}' ;}, $source );
