PLEASE HELP: Setting up variables for global use

[imimin]

How can I set a variable at one point (in a script or whatever) on my php page so it can be accessed later by another script on the same php page? Would I use GLOBAL and if so, what is the proper syntax?

Thank you!

I need to access a variable NOT a constant.

You can use the $GLOBALS array.

I am not sure how to set up an array to work with my current script. Is there another way we can do this without using an array? My son wrote most of the code below and is now moved out and I cannot really communicate with him now. I am really in a pinch to get this code finished - I need help in a desperate way!

I have a php script that is over 600 lines long. I declare the variable $test in 4 different IF statements below:

	$exclude_gnd=0;
	$exclude_1da=0;
	$exclude_2da=1;
	$exclude_3da=0;
	/* a little bit of searching through the name 
	to find out what kind of shipping to use   */

if(strpos($methodName, 'ground') !== false and $exclude_gnd!==1){
	if ($exclude_gnd==1){$test=1;}
	if($groundZone != '-'){
		$baseShippingCost = us_get_cost_for_lbs_and_zone('ups_commus48_gnd', $evalWeight, $groundZone);
		$shipDiscount = $shippingDiscounts['ground'];
	}
	/*elseif($groundZone = '-'){$baseShippingCost = 0;}*/
}
		else{$baseShippingCost = 0; }
//else{$baseShippingCost = 0; }

if((strpos($methodName, 'overnight') !== false or strpos($methodName, "next day") !== false) and $exclude_1da!==1){
	if ($exclude_1da==1){$test=1;}
	if($overNightZone != '-'){
		$baseShippingCost = us_get_cost_for_lbs_and_zone('ups_commus48_1da', $evalWeight, $overNightZone);
		$shipDiscount = $shippingDiscounts['overnight'];
	}
	/*elseif($overNightZone = '-'){$baseShippingCost = 0;}*/
	else{$baseShippingCost = 0; }
}
//else{$baseShippingCost = 0; }


if(strpos($methodName, '2nd') !== false and $exclude_2da!==1){
	if ($exclude_2da==1){$test=1;}
	if($twoDayZone != '-')
	{
		$baseShippingCost = us_get_cost_for_lbs_and_zone('ups_commus48_2da', $evalWeight, $twoDayZone);
		$shipDiscount = $shippingDiscounts['second'];
	}
	/*elseif($twoDayZone = '-'){$baseShippingCost = 0;}*/
	else {$baseShippingCost = 0;}
}
//else {$baseShippingCost = 0;}


if(strpos($methodName, '3 day') !== false and $exclude_3da!==1){
	if ($exclude_3da==1){$test=1;}
	if($threeDayZone != '-'){
		$baseShippingCost = us_get_cost_for_lbs_and_zone('ups_commus48_3ds', $evalWeight, $threeDayZone);
		$shipDiscount = $shippingDiscounts['third'];
	}
	/*elseif($threeDayZone = '-'){$baseShippingCost = 0;}*/
	else{$baseShippingCost = 0; }
}
//else{$baseShippingCost = 0; }

/*else{
	$baseShippingCost = $groundCost;
}*/

$tempArr = array($baseShippingCost, $methodName, $shipDiscount);
return $tempArr;
}

and then later on in the php page I try to retrieve the $test variable for use in this script:

$endTotalShippingCost = $dryIceCost + $totBoxCost + $shippingCost;

Can you please look at my code and tell me if it looks correct or if I can change it in some way and also if how I can call the $test variable later on in the php script (I need to call it when I get to the "$endTotalShippingCost = $dryIceCost + $totBoxCost + $shippingCost;" portion of the page.

Thank you for all of your help!

If your trying to access a variable that has already been defined in the same script then you don't need to do anything else.

I don't know how you are trying to use it, but to use your example, if you wanted to add $test to your $endTotalShippingCost calculation then you can just use it.

$endTotalShippingCost = $dryIceCost + $totBoxCost + $shippingCost + $test;

The only real exception is if you need to use it inside a function, in which case you would just declare it as global before you used it.

[imimin]

Could you tell me if my logic on the lines similar to:

if ($exclude_1da==1){$test=1;}

look right?

It seems that my $test variable is not being interpreted correctly? It does not print when I try to do a echo "$test"; on php page (browser does not print it out.

Thanks again!

The only issue would be if the variable is being used within a function definition. In that case, to make it globally accessible you would need to define it as global within each function where it is used, using the [man]global[/man] keyword:

function myFunc()
{
   global $test;
   // rest of function
}

To use my suggestion regarding $GLOBALS, you would just replace all instances of $test with $GLOBALS['test'] and then not worry about having to declare it as global anywhere (plus it is then obvious that it is a global variable, avoiding some of the maintenance problems that can be associated with global variables).

Could you tell me if my logic on the lines similar to:

if ($exclude_1da==1){$test=1;}

Your logic is fine but you need to make sure that $exclude_1da does = 1 as you set it to 0 at the start and I can't see where you change it.

For debugging purposes you may find it usefull to echo some of your variables out as you go through your if / else statements, because I would 'guess' that you think something is evaluating to true (or false) when it isn't.

We can't really see in the code that you have posted because you are using lots of variables which we don't see being set, so assume you set them earlier
