Question

I am having trouble showing a row from a database which has a list of skills as an array which is delimited by a commas. Fully annotated code with explanation below is what i’ve done sor far. All help is much appreciated. Thanks in advance.

// DB Connection here

    // Execute Query 
    $sql        =   "SELECT id, skills FROM p_info";
    $result     =   mysql_query($sql);
    $row        =   mysql_fetch_array($result);

    // Delimit array by comma
    $myArray = explode(',', $row['skills']);

    // Store as array
    $myArr   = array($myArray);

    /** 
    Assume the value of is skills row in the database is: type 1, type 2,  type 3, type 4 
    i would like to show these values each on a seperate <li> element hence using a loop. 

    <li> type 1</li>
    <li> type 2</li>
    <li> type 3</li>
    <li> type 4</li>

    My guess would be to use foreach loop..but im a little confused how to  go about this. Here whats i think logically:

    **/
    ?>
        <ul>
        <?
            foreach ( $myArr as $skills ) { 
        ?>
            <li><?=$myArr;?></li>

        <? 
            } // End loop 
        ?>
        </ul>

    <!-- Can someone tell me what im doing wrong? im fairly new to PHP but im a quick learner. :) -->

Remove $myArr = array($myArray); and do foreach ( $myArray as $skills ) { instead.
You are putting your array within a new array, so when you try to loop through it you end up with the original array.

Also change <?=$myArr;?> to <?=$skills;?>, you are looping through $myArray and storing every part in $skills temporarily, $myArray doesn’t change so it’s useless trying to echo it.
