How long can a php code execute?

I dont know if its the right question.

The thing is that, I have a list of users and their emails stored in my database.

Now I want to send a email to all of them with the help of a loop and setting a time interval delay (may be 5-10 seconds ).

foreach($users as $user){
     //code to send the email
}

I roughly have around 50 users. So will the code execute until the loop will complete? I mean is it a correct way to do?

What if I have hundreds or even thousands of users in future?

The default max execution time is 30 seconds. You can easily modify this by going to your php.ini file and changing max_execution_time option.

If you wish to modify max execution time within your PHP script, you can use this function: set_time_limit ( int $seconds ), you can also revert these changes later.

//Settings time limit to 0 will make the script execute without time limit(see comments).
set_time_limit (0);

foreach($users as $user){
     //code to send the email
}

set_time_limit (30);

By default the max_execution_time is 30 seconds. But I don't understand why you would want to stall a script for 5-10 seconds for every user when you're sending an e-mail. You may want to look at a cron job instead.
