76 going to grab something to eat and then back at working on the project
(and cursing at php for stupid design. Fun fact: in php you can use rand() or mt_rand() to get a random number, however rand() takes more time then mt_rand() and is less random......)

78 I am now curious in what situation you want to get a random number that isn't as random as it could be while also having it take longer to create ?
80 indeed, the use apparently only looks at what the value is when you define the function, not when you execute it.
PHP:
$someFunction=function() use($lol){ //the code will crash here already because $lol is not defined
echo $lol;
}
$lol="test";
$someFunction(); //even though I execute the function here81 It makes sense that that would crash if PHP just goes through the source file once, like C does, rather than scanning once to get the names of all the functions and global variables and then again to actually compile those functions, like Java. When you declare $someFunction in the above example, $lol doesn't exist yet, so it crashes.
What does the example on the previous page actually print? Your response confuses me.

85 But I thought it would print test2, and then you said indeed, and I was confused.
Is there a way to make a PHP function use the current value of a global variable, as opposed to the value when the function was defined?

86 Must have misread then, sorry 
Also, I am not going to go the path of globals, yes it is possible to do (but also a pain because php is weird). Instead I am just going to do it in a bit all over the place way (as that is still better then globals).

PHP:
//thanks to code igniter I am already working inside classes
class Card_interperter extends My_model{
public function doDamage(){
//code that deals damage here
}
public function executeEffect(){
$that=$this;
$dealDamage=function() use ($that){
$that->dealDamage();
}
$this->someVariableINeed="lols";
$dealDamage();
}
}
