[SOLVED] Putting Dynamic Arrays into array_intersect

[BrianCoyDesign]

Hello fellow freaks...

 

I'm hoping someone can help me.  I've created some code that takes an unknown number or arrays and creates a string (ugh) that can be placed into the array_intersect variable for comparison.

 

$c=0;

$newArray='';

foreach ($ship_methods_allowed as $module) {

$newArray .= '$ship_methods_allowed['.$c.'] , ';

$c++;

}

$newArray = rtrim($newArray,' , ');

 

eval("\$newArray = $newArray;");

$result = array_intersect($newArray);

 

 

If I put in more than one array I get the error that an unexpected , (comma) has been seen in the code.  I need the comma there and I need each variable to be seen as an array to get the results.

 

The $newArray variable comes out as a string "$ship_methods_allowed[0],$ship_methods_allowed[1]"

 

How do I get the array_intersect to see there correctly?

 

Any help would be appriciated.  I've been banging my head against a wall for a week now.

what does $ship_methods contain (what does a var_dump($ship_methods) produce) and what do you want $result to contain?

[BrianCoyDesign]

$ship_methods_allowed contains an array of modules based on the id of the product. 

 

For example the first array $ship_methods_allowed[0]= array("UPS","Shipping Based on Total Order","In Store Pickup");

Second Array would contain $ship_methods_allowed[1]= array("UPS","Shipping Based on Total Order","Freight");

Third - $ship_methods_allowed[2]= array("UPS","Shipping Based on Total Order");

 

So by comparing these I want to get back $result = array("UPS","Shipping Based on Total Order");

 

I can then use the result to turn on those 2 modules so they show on the shipping page.

 

var_dump($ship_methods_allowed) returns

 

array(1) { [0]=> array(4) { [0]=> string(15) "In Store Pickup" [1]=> string(0) "" [2]=> string(3) "UPS" [3]=> string(0) "" } }

for one your eval code is erroring

try:

<?php
eval("\$newArray = \"$newArray\";");
?>

1) I don't have a php environment handy, so this is completely untested.

 

2) Assuming the number of element in $ship_methods_allowed is unpredictable, I would try something like this:

 

$eval_string = "$result = array_intersect(";

for( $i = 0; $i < count( $ship_methods_allowed ); $i++ )
{
$eval_string .= "$ship_methods_allowed[" . $i . "], ";	
}

//trim off last ", "
$eval_string = substr($eval_string, 0, -2);

$eval_string .= ");";

eval($eval_string);

//now you should have a $result variable containing the intersection

 

3) Your var_dump() contradicted your explanation of what $shipping_methods_allowed contains. You should see everything in var_dump() that you expect to be in the array.

I'm getting Parse error: syntax error, unexpected '"', expecting T_STRING or T_VARIABLE or T_NUM_STRING  using the above code.

 

My statement was off as I only had one array.

[BrianCoyDesign]

When I modified the code slightly

 

$eval_string = "$result = array_intersect(";

for( $c = 0; $c < count( $ship_methods_allowed )+1; $c++ )
{
	$eval_string .= "$ship_methods_allowed[$c], ";	
}

//trim off last ", "
$eval_string = substr($eval_string, 0, -4);

$eval_string .= ");";

//eval($eval_string);
eval("\$eval_string=\"$eval_string\";");

 

I get = array_intersect(Array, Array);

as the result.

 

If I leave the eval the way it was in your code same I get an error on the equal sign.  I'm not sure why $result doesn't flow through to make the result show-up.

 

suggestions?

i get no errors in PHP 5 can you paste the specific error you are getting ???

Parse error: syntax error, unexpected '=' in /home/myprinti/public_html/components/com_virtuemart/themes/default/templates/checkout/list_shipping_methods.tpl.php(96) : eval()'d code on line 1

 

PHP Version 5.2.9

[darkfreaks]

please paste the full code so we can determine where the error is.

 

i have tested your above code in PHP 4 and 5 and i get no errors

		//echo $ship_methods_allowed[$i][$j] . "<br>";
	}
}
echo "<br>";
}
//Now that all the array have been created I need to take an put them all into one statement and compare ALL the ARRAYS at the same time to come up with final list.
$ship_methods_allowed[1] = array("UPS","Shipping Based on Total Order","In Store Pickup");
//$ship_methods_allowed[2] = array("UPS","Shipping Based on Total Order","In Store Pickup");
//$result = array_intersect($newArray,$ship_methods_allowed[1],$ship_methods_allowed[2]);


$eval_string = "$result = array_intersect(";

if you uncomment my code and comment his out it works

 

 

[BrianCoyDesign]

if you uncomment my code and comment his out it works

 

Are you refering to these two lines?

 

eval($eval_string);

//eval("\$eval_string=\"$eval_string\";");

 

When I switch those I get no error but I also don't get an clean answer

 

I receive this:  HERE:- = array_intersect(Array, Array);

 

For the line

 

echo "HERE:" . $result . "-" . $eval_string . "<br>";

 

 

I get nothing for print_r ($result);

 

I need an array of the results from the array_intersect.

[BrianCoyDesign]

I've spent over 6 hours today on this it's driving me nuts.  I don't understand what I'm not seeing here.  I just want the final result to be:

 

$result=array(result1,result2);

 

After the intersection based on the total matched items between the arrays.

[BrianCoyDesign]

Solved.... Ever have one of those walk away and then it will make sense moments?

 

The problem was I was using " double quotes in the creation instead of single quotes.  Here's the solution...

 

$eval_string = '$result = array_intersect(';

for($c=0; $c < count( $ship_methods_allowed ); $c++)
{
	$eval_string .= '$ship_methods_allowed[' . $c . '], ';	
}

//trim off last ", "
$eval_string = substr($eval_string, 0, -2);

$eval_string .= ');';

eval($eval_string);
