@set_time_limit(360); //设定脚本的最长执行时间为360秒，如果超过了时间限制，程序结束
总结一下：
这个php为自动安装程序做了初始化工作，包括生成一个错误类ecs_error对象（执行构造函数将公有成员变量$_template值设为‘message.dwt’），生成一个模板类template对象（执行构造函数将公有成员变量$path值设为'/upload/install/templates/'；告诉浏览器文本类型为text/html，编码格式utf8；设定脚本最长执行时间为360秒。
对于最后一条语句@set_time_limit(360)我有一些疑问想和大家分享一下。
set_time_limit函数实际上和修改php.ini中的max_execution_time可以起到一样的效果。这里说设定脚本最长执行时间为360秒，最初看到这条语句我陷入了一个误区：由于从顶层的index.php到这个php是一路require过来，并且在执行时require语句会被它所包含的文件直接替换，那么这个360秒到底是限制哪一个php的的执行时间。就在我百思不得其解时，看到了脚本这个词，然后忽然想到这个函数不是用来限制php文件的执行时间，php文件也不是脚本文件，这个函数是用来限制ecshop中用到的js之类脚本的执行时间，原谅我没文化，在此罗嗦了一大堆。
