Question

I have a code as shown below.This code throws our values says, 0.5 seconds on the output screen since I have run a foreach loop. Now, I want to work around with my variables $var1 , $var2 , $var3 (which is are got my a imposing a few functions on $value).

foreach ($predefinedarray as $key => $value) {
if ($predefined_var == NULL) {
 print "<b>$value</b> could not be processed.<p>";
 } else {
print "$var1,$var2,$var3>";
 }
}

Now, I want to get all $var1 after the whole foreach is done with the constraint that $var2 = "foo" ; How do I do this? Do i need to use SQL Databases for this or is there a simpler way of using javascript, jquery etc?

PS: Also, I want to make a download option that lets me download this data. So, I'm assuming once I figure out how the above data is tored, I can probably work around this too.

Thanks! John

Answer 1

Didn't really got what you were trying to say but as i understood 1)you iterate array and get the values suppose $value 2)you do something with $value and get 3 values $var1,$var2,$var3 3) you want the all $var1 when $var2="foo"

if this is what the question is then i suggest you create another array and fill the with $var1 data when $var2="foo" like

$the_var1_array=array();
foreach ($rawlist as $key => $value) {
    if ($id == NULL) 
     {
         print "<b>$value</b> could not be processed.<p>";
     } 
     else 
     {
        print "$var1,$var2,$var3>";
        if($var2=="foo")
        {
           $the_var1_array[]=$var1;
        }
     }
    }

Now that you have the array iterate through it and get all the $var1

Hope I understand the question right

Answer 2

I thought of that. But what if my "foo" is some variable that depends on my input array from the user?

Isn't that exactly what $varx are also? Function results depending on the input ($rawlist)?
