The mail function that comes with PHP is a pain in the ass. Even after configuring sendmail under win, I still cannot send emails. Using third-party pear/mail can directly connect to the mail sending server through SMTP. Such as (smtp.163.com). There is no need to install sendmail or other similar software on this machine.
Make sure the PEAR Mail package is installed.
<?php require_once "vendor/autoload.php"; $from = "test<test@163.com>"; $to = "test <test@outlook.com>"; $subject = "Hi!"; $body = "Hi,\n\nHow are you?"; $host = "smtp.163.com"; $port = "25"; $username = "test@163.com"; $password = "test123"; $headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject); $smtp = Mail::factory('smtp', array ('host' => $host, 'port' => $port, 'auth' => true, // 'debug'=>true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($to, $headers, $body); if (PEAR::isError($mail)) { echo("<p>" . $mail->getMessage() . "</p>"); } else { echo("<p>Message successfully sent!</p>"); } ?>
This is a non-encrypted method.
Most PHPer uses the mail function to send emails, but we can use other SMTP servers to send emails. It is recommended to use PEAR's mail package to send emails.
$subject = "This mail is sent from SMTP."; $mail_body = "This is the body of the mail which is sent using SMTP."; $from = "From: From Name <fromaddress@xpertdeveloper.com>"; $to = "To: To Name <toaddress@xpertdeveloper.com>"; $receiver = "toaddress@xpertdeveloper.com"; // Setting up the headers $headers["From"] = $from; $headers["To"] = $to; $headers["Subject"] = $subject; $headers["Reply-To"] = "reply@address.com"; $headers["Content-Type"] = "text/plain; charset=ISO-2022-JP"; $headers["Return-path"] = "returnpath@address.com"; // Setting up the SMTP setting $smtp_info["host"] = "smtp.server.com"; $smtp_info["port"] = "25"; $smtp_info["auth"] = true; $smtp_info["username"] = "smtp_user"; $smtp_info["password"] = "smtp_password"; // Creating the PEAR mail object : $mail_obj =& Mail::factory("smtp", $smtp_info); // Sending the mail now $mail_sent = $mail_obj->send($receiver, $headers, $mail_body); // If any error the see for that here: if (PEAR::isError($mail_sent)) { print($mail_sent->getMessage());}
The third case:
Before using the following source code, please configure the pear path and download the net_smtp package
Choose different setting methods according to your operating system in the php.ini file
; UNIX: "/path1:/path2" include_path = ".:./php/pear" ; ; Windows: "\path1;\path2" ;include_path = ".;c:\php\pear" require 'Net/SMTP.php'; $host = '126.com';//smtp服务器的ip或域名 $username= 'arcow';//登陆smtp服务器的用户名 $password= 'secret';//登陆smtp服务器的密码 $from = 'arcow@126.com'; //谁发的邮件 $rcpt = array('test@test.com', 'arcow@126.com');//可设多个接收者 $subj = "Subject: 你是谁 ";//主题 $body = "test it";//邮件内容 /* 建立一个类 */ if (! ($smtp = new Net_SMTP($host))) { die("无法初始化类Net_SMTP!\n"); } /* 开始连接SMTP服务器*/ if (PEAR::isError($e = $smtp->connect())) { die($e->getMessage() . "\n"); } /* smtp需要身份验证 */ $smtp->auth($username,$password,"PLAIN"); /*设置发送者邮箱 */ if (PEAR::isError($smtp->mailFrom($from))) { die("无法设置发送者邮箱为 <$from>\n"); } /* 设置接收邮件者 */ foreach ($rcpt as $to) { if (PEAR::isError($res = $smtp->rcptTo($to))) { die("邮件无法投递到 <$to>: " . $res->getMessage() . "\n"); } } /* 开始发送邮件内容 */ if (PEAR::isError($smtp->data($subj . "\r\n" . $body))) { die("Unable to send data\n"); } /* 断开连接 */ $smtp->disconnect(); echo "发送成功!"; ?>
The above is the entire content of this article. Three cases of PHP using pear_smtp to send emails. I hope it will be helpful for everyone to learn PHP programming.

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。

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。

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。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

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。

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。
