I've got some links in external php file and I want the sript to pick up this links in random way. please, help. Thanks

[brown2005]

can you explain a bit more mate? please....

when it picks them up what is it doing withit?

[Prismatic]

One way is to hold all the links in an array
[code]<?php
$LinkArr[1] = "http://www.google.com";
$LinkArr[2] = "http://www.yahoo.com";
$LinkArr[3] = "http://www.msn.com";
$LinkArr[4] = "http://www.phpfreakes.com";
?>[/code]

And then use rand() to grab one of those randomly
[code]<?php
$LinkToShow = rand(1, count($LinkArr));
?>[/code]

and then show the randomly chosen link
[code]<?php
echo $LinkArr[$LinkToShow];
?>[/code]

[Gruzin]

[brown2005]

[Gruzin]

yes, I want this links to be linked to the web-sites. I'am trying to make a descriptions for the links.... I mean when the link will be displayed I want some description under it

[Prismatic]

[code]<?php
/* The array to hold the links */
$LinkArr[1] = "http://www.google.com";
$LinkArr[2] = "http://www.yahoo.com";
$LinkArr[3] = "http://www.msn.com";
$LinkArr[4] = "http://www.phpfreakes.com";

/* The array to hold the descritions for the links */
$LinkArrDesc[1] = "This is a descrition for google!";
$LinkArrDesc[2] = "This is a descrition for Yahoo!";
$LinkArrDesc[3] = "This is a descrition for MSN!";
$LinkArrDesc[4] = "This is a descrition for PHPFreaks!";

/* Grab a link randomly */
$LinkToShow = rand(1, count($LinkArr));

/* Now show the link as a clickable link and the descritpion under it */
echo "<a href='". $LinkArr[$LinkToShow] ."'>". $LinkArr[$LinkToShow] ."</a><br>". $LinkArrDesc[$LinkToShow];

?>[/code]

[Gruzin]

Thanks a lot you realy helped me:) can I make all this links to be displayed? Thanks

[Prismatic]

To show all links use this:

[code]<?php
for($i=1; $i <= count($LinkArr); $i++){
echo "<a href='". $LinkArr[$i] ."'>". $LinkArr[$i] ."</a><br>•". $LinkArrDesc[$i] ."<br><br>";
}
?>[/code]

[Gruzin]

Thank you very much!!! You are so Kind:)

[Prismatic]

No problem :)

[Gruzin]

And one more thing please:) Can we display only first 20 links in random way?

[Prismatic]

Yep. This code will show the first 20 randomly, or all of them in random order if the ammount of links is under or equal to 20.
[code]<?php
if(count($LinkArr) > 20)
$Max = 20;
else
$Max = count($LinkArr);

for($i=1; $i <= $Max; $i++){
$LinkToShow = rand(1, count($LinkArr));
echo "<a href='". $LinkArr[$LinkToShow] ."'>". $LinkArr[$LinkToShow] ."</a><br>•". $LinkArrDesc[$LinkToShow] ."<br><br>";
}
?>[/code]

[Gruzin]

Thanks man, you are great:)

[Prismatic]

Yep, no problem :)

[redarrow]

Please also add the code that let's users get the random link from a database ok cheers mate.

example


explode("",$links);

foreach($links AS $LinkArr);

/* The array to hold the links */
$LinkArr[1] = "http://www.google.com";
$LinkArr[2] = "http://www.yahoo.com";
$LinkArr[3] = "http://www.msn.com";
$LinkArr[4] = "http://www.phpfreakes.com";


somthink like that if the links are in the database

This code needs to be corrected theo cheers.
