?>本人新手，網上下的php分頁代碼，看是看懂了，但運行后有錯誤！
Parse error: syntax error, unexpected T_IF 第21行有錯：if($this->page_num > $this->page_size){   
求幫組～  

Answer 1

语法错误? if($this->page_num > $this->page_size){ 没有错才对。

Answer 2

我也觉得应该没错啊！但运行后就是报错。我用的是PHP4

Answer 3

小伙仔什么年代了。还用php4。用php5吧。

Answer 4

就算是php4，这个错误也不应该吧，你运行报错吗？

Answer 5

        $this->page_url = $_SERVER['SCRIPT_NAME'];     //獲取當前腳本的路徑
                                                ַ
看到了么
第21行前面多了一行  字符，这会导致解析错误的，把这行去掉，或则去掉这个特殊字符，就行了
