display random results from multiple arrays

[poe]

i have 3 arrays of links (payed, localad, personal).

 

these are for banners i want to show on my site.

 

payed = these links, people payed for

 

localad = these are my own banner ads which advertise 'buy banner today'

 

personal = these are to my personal links (my wife isnt going to pay for an ad space on my website! )

 

 

$payed = array(
array( 'url'=>'www.link1.com', 'img'=>'img1.jpg' ),
array( 'url'=>'www.link2.com', 'img'=>'img2.jpg' ),
array( 'url'=>'www.link3.com', 'img'=>'img3.jpg' ),
array( 'url'=>'www.link4.com', 'img'=>'img4.jpg' ),
);


$localad = array(
array( 'url'=>'advertise.html', 'img'=>'buynow.jpg' ),
array( 'url'=>'advertise.html', 'img'=>'info.jpg' ),
array( 'url'=>'advertise.html', 'img'=>'clickhere.jpg' ),
);



$personal = array(
array( 'url'=>'myblog.com', 'img'=>'my.jpg' ),
array( 'url'=>'wifeblog.com', 'img'=>'wife.jpg' ),
array( 'url'=>'myfriendblog.com', 'img'=>'myfriend.jpg' ),
array( 'url'=>'wifefriendblog.com', 'img'=>'wifefriend.jpg' ),
);

 

 

 

i have another array which shows the type of banner to show, depending on what page you are on. eg, some pages i have set to show 3 banners, some pages i have set to show, 4 banners, or 5 banners. etc.. (goes from 1 to 5)

 

$level = array(
array( 'show'=>1, 'payed'=>1, 'localad'=>0, 'personal'=>0, ),
array( 'show'=>2, 'payed'=>1, 'localad'=>1, 'personal'=>0, ),
array( 'show'=>3, 'payed'=>2, 'localad'=>1, 'personal'=>0, ),
array( 'show'=>4, 'payed'=>3, 'localad'=>1, 'personal'=>0, ),
array( 'show'=>5, 'payed'=>3, 'localad'=>1, 'personal'=>1, ),
);

 

eg..

$level[2]; is equivalent to:

array( 'show'=>3, 'payed'=>2, 'localad'=>1, 'personal'=>0, ),

means 2 random payed ads are shown + 1 localad = 3 total ads shown

 

and

$level[4]; is equivalent to:

array( 'show'=>5, 'payed'=>3, 'localad'=>1, 'personal'=>1, ),

means 3 payed ads shown + 1 localad + 1 personal = 5 total ads shown

 

etc....

 

 

 

how do i grab the ads from their respective arrays?

 

is there a way to condense things so that i can loop trough my code and depending on the $level array 'key' that has value greater than 0. grab the links from that array since they have the same name?

 

right now i have: (assuming i am looking for 3 ads)

 

$rand_payed[] = array_rand( $payed, level[2][payed] );

$rand_localad[] = array_rand( $localad, level[2][localad] );

$rand_personal[] = array_rand( $personal, level[2][persoanl] );

 

 

now im stuck!!!

 

thanks

I HOPE this is what you meant...

// Maybe shuffle the array to make the items not be grouped by type?

print_r($linksArray);

You and your overdeveloped sense of simple solutions must you beat me in speed and readability so often?... it hurts my confidence!

I guess I'm used to deadlines and working on fixed price jobs, so I try to keep two acronyms in mind

 

MNC - minimum necessary code

MDE - maximum desired effect
