I am currently following a tutorial that teaches how to create a queue in php. An infinite loop was created in a php script. I simplified the code in order to focus on the question at hand:
while(1) {
echo 'no jobs to do - waiting...', PHP_EOL;
sleep(10);
}
I use PuTTy (with an SSH connection) to connect to the linux terminal in my shared hosting account (godaddy). If I run php queuefile.php in the terminal, I know it will run with no problems (already tested the code with a finite for loop instead of the infinite while loop).
QUESTION: How could I exit out of the infinite loop once it has started? I have already read online the option of creating code that "checks" if it should continue looping with something like the following code:
$bool = TRUE;
while ($bool)
{
if(!file_exists(allow.txt)){$bool = FALSE}
//... the rest of the code
though I am curious if there might be a command I can type in the terminal, or a set of keys I can push that will cause the script to terminate. If there is any way of terminating the script, or if there is a better way to make the previous "check", I would love your feedback!
