调用

<?php

//引入发送邮件类
require("smtp.php");
//使用163邮箱服务器
$smtpserver = "smtp.163.com";
//163邮箱服务器端口
$smtpserverport = 25;
//你的163服务器邮箱账号
$smtpusermail = "xxx@163.com";
//收件人邮箱
$smtpemailto = "xxx@qq.com";
 
//你的邮箱账号(去掉@163.com)
$smtpuser = "xxx";//你的163邮箱去掉后面的163.com
//你的邮箱密码
$smtppass = "xxx"; //你的163邮箱SMTP的授权码,千万不要填密码!!!
 
//邮件主题
$mailsubject = "测试邮件发送";
//邮件内容
$mailbody = "PHP+MySQL";
//邮件格式(HTML/TXT),TXT为文本邮件
$mailtype = "TXT";
//这里面的一个true是表示使用身份验证,否则不使用身份验证.
$smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);
//是否显示发送的调试信息
$smtp->debug = TRUE;
//发送邮件

php怎么把负数转为正整数php怎么把负数转为正整数Apr 19, 2022 pm 08:59 PM

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”。

php怎么除以100保留两位小数php怎么除以100保留两位小数Apr 22, 2022 pm 06:23 PM

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怎么根据年月日判断是一年的第几天php怎么根据年月日判断是一年的第几天Apr 22, 2022 pm 05:02 PM

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。

php字符串有没有下标php字符串有没有下标Apr 24, 2022 am 11:49 AM

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。

php怎么判断有没有小数点php怎么判断有没有小数点Apr 20, 2022 pm 08:12 PM

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怎么读取字符串后几个字符php怎么读取字符串后几个字符Apr 22, 2022 pm 08:31 PM

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。

php怎么查找字符串是第几位php怎么查找字符串是第几位Apr 22, 2022 pm 06:48 PM

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。

php怎么设置implode没有分隔符php怎么设置implode没有分隔符Apr 18, 2022 pm 05:39 PM

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
