[SOLVED] HELP - Looping Arrays

[bronzemonkey]

I'm looking to store a list of links and associated text in a php array and have my web pages display a small number of them at any given time. I need some help with the php needed to display these. Here is my code that is stored in a separate php file:

 

<?php 
$page = $_SERVER['PHP_SELF'];

$article = array();
$article[] = array("http://www.domain1.com/article/topic/","Link Title","Link Text","Link Description");
$article[] = array("http://www.domain2.com/article/topic/","Link Title","Link Text","Link Description");
$article[] = array("http://www.domain3.com/article/topic/","Link Title","Link Text","Link Description");
$article[] = array("http://www.domain4.com/article/topic/","Link Title","Link Text","Link Description");
$article[] = array("http://www.domain5.com/article/topic/","Link Title","Link Text","Link Description");
$article[] = array("http://www.domain6.com/article/topic/","Link Title","Link Text","Link Description");
$article[] = array("http://www.domain7.com/article/topic/","Link Title","Link Text","Link Description");

if($page == '/links.php') {
echo "      <h3>Articles</h3>\n";
echo "      <ul>\n";
foreach ($article as $part) {
echo "        <li>\n";
echo "          <h4><a href=\"$part[0]\" title=\"$part[1]\">$part[2]</a></h4>\n";
echo "           <p>$part[3]</p>\n";
echo "         </li>\n";
}
echo "      </ul>\n";
}

else {
}
?>

 

If the page is my "links page" then all the links get displayed. But I am having trouble writing some php that works for the else{} part, which must only display the first 5 links (and their associated text) in the main array. Thanks for any help.

Try this in your else block

<?php
    echo "<h3>5 first articles</h3>\n";
    echo "<ul>\n";
    for($i=0; $i<5;$i++) {
        $part = $article[$i];
        echo "<li>\n";
        echo "<h4><a href=\"".$part[0]."\" title=\"".$part[1]."\">".$part[2]."</a></h4>\n";
        echo "<p>".$part[3]."</p>\n";
        echo "</li>\n";
    }
    echo "</ul>\n";
?>

Thanks for your help, here's the final form of the code.

 

<?php
$page = $_SERVER['PHP_SELF'];

$article = array();
$article[] = array("1","2","3","4");
$article[] = array("1","2","3","4");
$article[] = array("1","2","3","4");
$article[] = array("1","2","3","4");
$article[] = array("1","2","3","4");
$article[] = array("1","2","3","4");
$article[] = array("1","2","3","4");
$article[] = array("1","2","3","4");

echo "      <h3>Articles</h3>\n";
echo "      <ul>\n";
if($page == '/links.php') {
foreach ($article as $part) {
echo "        <li>\n";
echo "          <h4><a href=\"$part[0]\" title=\"$part[1]\">$part[2]</a></h4>\n";
echo "           <p>$part[3]</p>\n";
echo "         </li>\n";
}
}
else {
for($i=0; $i<5;$i++) {
$part = $article[$i];
echo "        <li>\n";
echo "          <h4><a href=\"$part[0]\" title=\"$part[1]\">$part[2]</a></h4>\n";
echo "           <p>$part[3]</p>\n";
echo "         </li>\n";
}
}
echo "      </ul>\n";
?>
