[SOLVED] simple array question

[jfarthing]

This is probably simple, I just cant figure out a method.  Let's say I have an array like the following:

array("Green:1","Yellow:2","Blue:3")

And I stored the info in the database in the form of just that number.  Now, when I retrieve the info from the database, I need to just pull the text from that same array.  Say a user chose number 2.  I need to access this particular array and display "Yellow" not "Yellow:2"  Thanks in advance!!

Use explode

I understand the explode, but thats just to seperate "Yellow" from ":2".  How do I determine that "Yellow:2" is the array value I need from just 2?

[cooldude832]

why do you need those numbers there if you store a number in your array then you say

$colors[$dbnumber];

and fyi if that is what you doing green is 0 not 1 yellow is 1 not 2 etc.

[jfarthing]

I used my own numbering system when I created the array if you look at my code above and that was to avoid having 0 used as a key.

[PHP_PhREEEk]

<?php
$colorArray = array(1 => 'Green', 'Yellow', 'Blue');

// pull number from database $color = $row['color']

echo $colorArray[$color];
?>

so it will automatically set 2, 3 and so on after setting 1?

Actually, I just figured that one out myself, but one more question.  What if I want an array of the months of the years, and I want the starting zero included in the key on the first 9 months eg. 01 => "January" or would I have to set them each manually?

[PHP_PhREEEk]

yes... what we created above was a numerical index starting at 1 instead of zero. By needing to prepend each single digit with 0, we would need an associative array. Each element would then be a string, and need to be manufactured. There would be a REALLY EASY way to do that, using a loop and the DATE function...

 

Can you figure it out? = ^)
