passing variable to the function parameter before adding a cron about cron HOT 5 CLOSED

Hi, yes, [...] within user-defined functions a local function scope is introduced. Any variable used inside a function is by default limited to the local function scope. Please have a look at the Variable scope documentation.
This should help:

use Illuminate\Support\Facades\Log;
...
while(someloop){
	$variable_from_outside=0;
	$variable_from_outside++;
	\Cron::add('samplecron', '* * * * *', function() {
                global $variable_from_outside;
		Log::info('$variable_from_outside: '.$variable_from_outside);
	}, false);
}

or maybe

use Illuminate\Support\Facades\Log;
...
while(someloop){
	$variable_from_outside=0;
	$variable_from_outside++;
	\Cron::add('samplecron', '* * * * *', function(&$variable_from_outside) {
		Log::info('$variable_from_outside: '.$variable_from_outside);
	}, false);
}

This Stackoverflow entry could help, too.

Hmm.. ive tried both solution just now.. seems theyre still not working as expected..
1st solution turns out to be just initializing the variable inside the function..
2nd solution gives this error

we've also tried to use private class variables, but still no luck. i have some idea now on how i could pass an outside variable, but it includes some modification in the codes within the package(which is as much as posible i would like to avoid.).

Ah I see. The second solution does not work, because I call the function without Parameters ($return = $job['function']();). Please try the use keyword.

use Illuminate\Support\Facades\Log;
...
while(someloop){
	$variable_from_outside=0;
	$variable_from_outside++;
	\Cron::add('samplecron', '* * * * *', function() use ($variable_from_outside) {
		Log::info('$variable_from_outside: '.$variable_from_outside);
	}, false);
}

from cron.

ah thats it.. it works now! i ddint even know that was possible.. thanks!
im so sorry, its my first time encountering this kind of problem and solution. but thanks a lot, its a new learning for me..
