如果你使用的是封装好的类
例如
function fetch_array($query, $result_type = MYSQL_ASSOC) {
return mysql_fetch_array($query, $result_type);
}
[/code]
会报这个错误
这是应为,你传递的$query是布尔值,而mysql_fetch_array 里面的参数需要的是资源类型,这是,你的程序会判定你传递的参数错误,
我们可以
function fetch_array($query, $result_type = MYSQL_ASSOC) {
return @mysql_fetch_array($query, $result_type);
}
在前面使用@来禁止错误提示,或者
试用判读语句来执行这个语句,
if(这个参数)
{
执行
}
