主要集中在 upload/includes/cls_template.php 文件中:

1:line 300 :

原语句:

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

修改为:

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

2:line 495:

原语句:

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

修改为:

$replacement = preg_replace_callback("/(/'//$[^,]+)/" ,

function($matcher){

return stripslashes(trim($matcher[1],'/''));

},

var_export($t, true));

$out = "<?php /n" . '$k = ' . $replacement . ";/n";

3:line 554: //zuimoban.com 转载不带网址,木JJ

原语句:

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

修改为:

$val = preg_replace_callback("//[([^/[/]]*)/]/is",

function ($matcher) {

return '.'.str_replace('$','/$',$matcher[1]);

},

$val);

4:line 1071:

原语句:

$replacement = "'{include file='.strtolower('//1'). '}'";

$source = preg_replace($pattern, $replacement, $source);

修改为:

$source = preg_replace_callback($pattern,

function ($matcher) {

return '{include file=' . strtolower($matcher[1]). '}';

},

$source);
