Help me with my homework ;D

[Jade Elizabeth]

So I'm learning PHP and I have been given this monstrosity.

Code Select Expand

$uni = get_uni_scores();

function get_uni_scores() {
$uni = array();
$uni['university_name'] = "Melbourne University";
$uni['teaching_score'] = 89.0;
$uni['int_outlook_score'] = 12;
$uni['ind_income_score'] = 89;
$uni['research_score'] = 13;
$uni['citations_score'] = 89;

// Overall score
$uni['overall_score'] = ($uni['teaching_score'] + $uni['int_outlook_score'] + $uni['ind_income_score'] + $uni['research_score'] + $uni['citations_score']);

return $uni;
}


On a technicality I did the calculation part ha ha. I can't change it to be in a DB because that's in the next part but I want to use a foreach loop so I don't have to do 100 lines of <li> crap . Anyway I have got it to show the values but I was hoping to get the variables too so I can do little headings/classes based on it (like <li class="over-score">).

Can someone please help me figure it out?

Okay so you have a single row of information, foreach would only get you one row, and one li. How do you plan on storing multiple rows of information or different universities?

Do a search for key value pairs, this should point you in the right direction.

Edit: Also look at multi-dimensional arrays for storing numerous universities until you can use a database to store data, crude for now but it works.

I don't. I have that array, that's what I am allowed to work with (no database, only one university). I have a database for part two of my assignment which I will be doing MVC style ha ha.

Do a search for key value pairs, this should point you in the right direction.

But it's not set out like that sort of array...will that still work?

[Dragooon]

So, you have that one dimensional array and you can only use that? You need a 2 dimensional array to be applicable for a foreach loop, when you are storing multiple universities. A 2-D array is basically a array in which each element is also a array, in your case it would mean each element stores a university's data. If you only have one university, you can straight away use that for displaying data without the need of a loop.

Okay I will look that up. Give me like 10 mins.

[ziycon]

If your going to store multiple universities, you would be using a 2D array (like Dragooon said) as your question currently stands. You can use nested foreach loops to output key/value pairs on a 2D array.

This will give you the general idea of how the foreach loop can be used with key/value pairs:

Okay how do I do the calculation part?

Code Select Expand

$uni = array(
                array(
                      university_name => "Melbourne University",
                      teaching_score => 89.0,
                      int_outlook_score => 12,
                      ind_income_score => 89,
                      research_score => 13,
                      citations_score => 89,
                      overall_score => ,
                    ),
             );


Also is there a way to make "ind_income_score" be "Income Score" when output?

Here's what I need to end up with....

Code Select Expand

<?php
foreach ($uni as $u)
{
echo '
<li class="[key]">
<span class="topic">[title]</span>
<div class="percentage-container">
<div class="percentage overall-score" style="width: [u]">
<span class="fig">[u]</span>
</div>
</div>
</li>';
}
?>


Where [title] is [key] but nicer (University Name)
Where [key] is the variables (university_name)
Where [u] is the value (Melbourne University)

You sure you won't marry me, Lizzy?

[Dragooon]

Ah that's simpler then, you need to use key => value loop, like

foreach ($uni as $key => $value)

Now for the labels what you can do is what SMF does, make an array with each key having their nice text label similar to

$labels = array(
    'university_name' => 'University Name',
);
...and so on and then use $labels[$key] where you need to display the text label.

Oh no you're too late!

I just got engaged to my boyfriend Michael ha ha.

Ohhh that is such a good idea. Then I can have labels, unis .

Thanks so much!

So I have to use the same code as above (in first post) but re-write it into a "new array" I can call for use in this pie graph:

https://google-developers.appspot.com/chart/interactive/docs/quick_start

The step I am stuck on is LITERALLY "since the data for the pie is not coming directly from the $uni array you will need to build a seperate array in the uni.php file to send the correct data to the view"

I don't understand what that says at all. I've been through their guide. Without doing it for me can someone explain in idiots terms or send me in the right direction please ?
