Here is the test file:
require("class.phpmailer.php"); //The downloaded file must be placed in the directory where the file is located
$mail = new PHPMailer(); //Create an email sending class
$address = "The email address of the user who received the email";//The email address of the user who received the email
$mail->IsSMTP(); //Send using SMTP
$mail->Host = "smtp.qq.com"; // Your business post office domain name
$mail->SMTPAuth = true; // Enable SMTP authentication function
//The following $mail->Username, $mail->Password, $mail->From are required
$mail->Username = "The email address of the user who sent the email"; // The email address of the user who sent the email
$mail->Password = "Password of the mailbox of the user who sent the mail"; // Password of the mailbox of the user who sent the mail
$mail->Port=25;
$mail->From = "The email address of the user who sent the email"; //Email address of the email sender
//$mail->FromName = "10-php";
$mail->AddAddress("$address",'The following recipient name is optional');//The recipient address can be replaced with any email mailbox you want to receive mail, the format is AddAddress(" Recipient email","Recipient name")
//$mail->AddReplyTo("", "");www.2cto.com
//$mail->AddAttachment("/var/tmp/file.tar.gz"); // Add attachment
//$mail->IsHTML(true); // set email format to HTML //Whether to use HTML format
$mail->Subject = "PHPMailer test email"; //Email title
$mail->Body = "Hello, this is a test email"; //Email content
$mail->AltBody = "This is the body in plain text for non-HTML mail clients"; //Additional information, can be omitted
If(!$mail->Send())
{
echo "Failed to send email.
";
echo "Error reason: " . $mail->ErrorInfo;
exit;
}
echo "Email sent successfully";

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。

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)”。

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。

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),
