***SOLVED***building an associative array by comparing 2 arrays

[ultimatemonty]

I've got two arrays that are being compared in a function. The function is supposed to loop through all the values one array, looking for matches in another array. If it finds a match, it sets an element in the third array to 1. If it finds no matches, it sets the element to 0.

Here's the code.
[code]function doClassTakenList($classes,$courses)
{
$i=0;
$count = count($classes);
do
{
          $class = $classes[$i];

if(array_search($class,$courses))
{
$list[$class][0] = '1';
}
else
{
$list[$class][0] = '0';
}
$i++;
}
        while($i<$count);
return($list);
} [/code]
$classes is a one-dimensional, numerically indexed array containing a list of all classes for a program. IE:
[code]$classes = array('SPEC 3110','SPEC3120','SPEC3130','SPEC3140','INTP4010');[/code]
$courses is a one-dimensional, numerically indexed array containing a list of classes a student has taken. IE:
[code]$courses = array('SPEC 3110','SPEC3180','INTP4010');[/code]
$list is an array containing each class and a '1' (for taken) or a '0' (for not taken).
instead of returning a numerically indexed, multi-dimensional array (which makes it a real PITA to access the classnames in the $list array), I'd like to build the array something like:
[code]if(array_search($class,$courses))
{
$list[$class => '1'];
}
else
{
$list[$class => '0']
} [/code]
this way it's easier to get the class and the associated value.
using that particular example, I get a [b]Parse error: syntax error, unexpected T_DOUBLE_ARROW, expecting ']'[/b]

anyone have any ideas of how to build what I'm needing?

SOLVED!
solution was very simple once I cleared my head and tackled it again...
[code]function doClassTakenList($classes,$courses)
{
$i=0;
$count = count($classes);

do
{
$class = $classes[$i];

if(array_search($class,$courses))
{
$list[$class] = '1';
}
else
{
$list[$class] = '0';
}
$i++;
} while($i<$count);
return($list);
}[/code]

Here's a much simpler method
[code]<?php
function doClassTakenList($classes,$courses)
{
    foreach ($classes as $class) {
       $list[$class] = (in_array($class,$courses))?'1':'0';
    }
    return $list;
}
[/code]

However, I followed your example of setting the value as the string of 0 or 1. It would be better to set the values as true/false so that you can do a true false tests on it. This is what I would use:

[code]<?php
function doClassTakenList($classes,$courses)
{
    foreach ($classes as $class) {
        $list[$class] = in_array($class,$courses);
    }
    return $list;
}
[/code]
