copied!<p>I am relatively new to arrays, and struggling with the amount of information out there to solve my problem succinctly. This is as far as I have progressed.</p> <p>My code:</p> <pre><code><?php $imagearrdisplay = ",8,7,22,"; $displayitem = explode(",", $imagearrdisplay); for($i = 0; $i < count($displayitem); $i++){ echo " <div class='banner'><img src='/images/transitions/$displayitem[$i].jpg' /></div> Count: $i = $displayitem[$i] "; } ?> </code></pre> <p>It currently returns a result of:</p> <pre><code><div class='banner'><img src='/images/transitions/.jpg' /></div> Count: 0 = <div class='banner'><img src='/images/transitions/8.jpg' /></div> Count: 1 = 8 <div class='banner'><img src='/images/transitions/7.jpg' /></div> Count: 2 = 7 <div class='banner'><img src='/images/transitions/22.jpg' /></div> Count: 3 = 22 <div class='banner'><img src='/images/transitions/.jpg' /></div> Count: 4 = </code></pre> <p>What I would like to achieve is the following:</p> <ol> <li><p>To remove the first and last comma within the imagearraydisplay when it explodes so that I do not end up with a blank image at the beginning and end.</p></li> <li><p>Randomise the results of the array</p></li> <li><p>Perform an if / else function to find the [0] and adjust the first result so that I can use css to style the image accordingly.</p></li> </ol> <p>To be able to then produce an outcome that looks like:</p> <pre><code><div class='firstbanner'><img src='/images/transitions/22.jpg' /></div> <div class='banner'><img src='/images/transitions/7.jpg' /></div> <div class='banner'><img src='/images/transitions/8.jpg' /></div </code></pre> <p>I know it's possible, though struggling through the maze of tutes out there. Any help would be really appreciated.</p>
