die("")是什么用的?你门跟数据库通信是采用pear db方式还是具体库函数

die("")是什么用的?你门跟数据库通信是采用pear db方式还是具体库函数

[伍子V5]

终止运行，并返回一个字符串

die跟exit一样

exit
(PHP 3, PHP 4 )

exit -- Output a message and terminate the current script
Description
void exit ( [string status])

void exit ( int status)


注: This is not a real function, but a language construct.

注: PHP version >= 4.2.0 does NOT print the status if it is an integer.

The exit() function terminates execution of the script. It prints status just before exiting.

If status is an integer, that value will also be used as the exit status. Exit statuses should be in the range 1 to 254, the exit status 255 is reserved by PHP and shall not be used.

例子 1. exit() example

<?php

$filename = '/path/to/data-file';
$file = fopen ($filename, 'r')
or exit("unable to open file ($filename)");

?>




注: The die() function is an alias for exit().

pear

mysql_query("CREATE TABLE $strTableNameMsg(......) or die(mysql_error())
不会显示错误

我不习惯用PEAR，一般数据库不会轻易更换，虽使代码的转移变得方便，但是是以牺牲运行效率为代价的，我个人还是喜欢用数据库本身的函数。
