Find variable based on inputted value

[rslnerd]

Sorry if I sound like a total idiot, but I don't know how to do this 

 

I have a bunch of array variables that I need to access based on an inputted value.  It's a dropdown menu, so the values are predetermined.

 

For example:

<?php
$var1 = array("blah1","blah2","blah3","blah4");
$var2 = array("foo1","foo2","foo3","foo4");
$var3 = array("nothing1","nothing2","nothing3","nothing4");
?>
<form method="get" action="this.php" name="this">
<select>
<option value="var1">1</option>
<option value="var2">2</option>
<option value="var3">3</option>
</select>
</form>

 

So I want it so that if the user selects option 1, var1 can be accessed and i can use the array to do the calculation needed... How can I use the value to access the variable?

<?php
if (isset($select_var))
{
  switch($select_var)
    case 1:
      $var_array = array("blah1","blah2","blah3","blah4");
      break;
    case 2:
      $var_array = array("foo1","foo2","foo3","foo4");
      break;
    case 3:
      $var_array = array("nothing1","nothing2","nothing3","nothing4");
      break;
}

// do what ever you want with $var_array
?>
<select name='select_var'>
<option value="var1">1</option>
<option value="var2">2</option>
<option value="var3">3</option>
</select>

 

Think this will help

Thanks!  I've never used switch before, so I wouldn't have thought of that... Thanks a ton!

alternatively...

 

<?php
$var[1] = array("blah1","blah2","blah3","blah4");
$var[2] = array("foo1","foo2","foo3","foo4");
$var[3] = array("nothing1","nothing2","nothing3","nothing4");

// example:
print_r($var[$_GET['this']]);
?>
<form method="get" action="this.php" name="this">
<select>
<option value="var1">1</option>
<option value="var2">2</option>
<option value="var3">3</option>
</select>
</form>
