① Looking for an application that can send emails online, I found a file called "sendmail.exe" under the Windows system. When downloading, go to the official website. It not only contains the exe execution program, but also various configurations.
②Configuration: In the sendmail.ini file, we take QQ mailbox as an example.
smtp_server=smtp.qq.com
smtp_port=465
smtp_ssl=auto
error_logfile=error.log
auth_username=29152 2145(email account)
auth_password=saturday123456(email password)
force_sender=291522145@qq.com
③Configure php.ini:
[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = smtp.qq.com
sendmail_from = 291522145@qq.com
sendmail_path = "i :abcsendmailsendmail.exe -t"
mail.add_x_header = On
④php program:
<span><?php </span><span><em>ini_set</em></span>(<span>'display_errors'</span>,<span>0</span>); <span><em>error_reporting</em></span>(<span>-</span><span>1</span>); <span><em>ini_set</em></span>(<span>'log_errors'</span>,<span>1</span>); <span><em>error_log</em></span>(<span>'today ids rain'</span>,<span>1</span>,<span>'291522145@qq.com'</span>);</span>
After everything is configured, restart the service, and then run the php program, you can find your qq mailbox There is an extra email.
The above introduces the error log email sent by php, including php and error content. I hope it will be helpful to friends who are interested in PHP tutorials.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。
