set_time_limit(0);
The number in the brackets is the execution time. If it is zero, it means that it will be executed permanently until the end of the program. If it is a number greater than zero, the program will end after the set number of seconds, regardless of whether the program is completed.
A simple example, display 1500 statements on a web page. If the expiration time is not set, the program will end when it reaches 791. If the comment character // before set_time_limit(0); is removed, the program will not end until 1 .
Copy the code The code is as follows:
//set_time_limit(0);
$i=1500;
include ("inc/conn.php");
while($i> 0)
{
$sql="INSERT INTO php (php)
VALUES ('$i')";
if ($conn->execute($sql)===flase)
{
//echo " Data insertion error ".$conn->errormsg();
}
else
{
$phpid=$conn->Insert_ID();
echo $i." has been stored in the database, number: ".$phpid ;
}
$i--;
echo "
";
}
?>
The above introduces the function of limitlessremote php set_time_limit0 to set the program execution time, including the content of limitlessremote. I hope it will be helpful to friends who are interested in PHP tutorials.

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
