PHP中error_log()函数的使用方法,phperror_log
本文实例讲述了PHP中error_log()函数的使用方法。分享给大家供大家参考。具体分析如下:
今天遇到一个问题需要调试,但是只能通过日志打印调试,就用到了error_log这个函数
需要打印的是一台服务器发送到我们服务器的post数据
代码如下:(key和value都打印了)
复制代码 代码如下:
if(!empty($_POST) ){
while (list($key, $val) = each($_POST))
{
@error_log("$key => $val", 3,'/tmp/test_post_allstarpay.log' );
}
}
error_log有四个参数 ,主要是前3个,第一个是log日志写入内容,第二个是日志存入方式3表示存入指定位置,第三个是存入位置
服务器用的是centos ,tmp有读写权限 所以就写入tmp内了
error_log会自动生成相应的log文件,不需要手动创建!
希望本文所述对大家的php程序设计有所帮助。
