I'm trying to create an unordered list in php and display it to html file

Question

I'm very new to PHP/Programming, so you can understand my frustration. Don't get me wrong I'm loving it.

My objective is to create an unordered list in PHP and display it in html.

I was able to successfully create the unordered list, and it shows up correctly.

My issue is when I try to display it to an HTML file using the fopen(); & fwrite();.

The error i'm getting is that it only display the last three values in my array when I switch over to my .html file. My code is below, any advice is appreciated.

$colors = array (
      0 => array ("red", "black", "white"),
      1 => array ("yellow", "blue", "green"),
      2 => array ("orange", "grey", "pink"),
      3 => array ("purple", "brown", "clear"),
);

foreach ($colors as $value) {
    echo "<ul>";
    $couleur = "<li>". implode ("</li><li>", $value) ."</li>";
    echo $couleur;
    echo "</ul>";
}

$y = fopen ("list.html", "w");
fwrite ($y, $couleur);

is there a special reason you need to display this on the .html file and not directly display it from the .php file? you are also overwriting $couleur on each foreach iteration. try using $couleur[] = ... — Matt

Yes, you're overwriting $couleur every iteration of your loop. Define $couleur aas an empty string before the loop; don't echo inside the loop, but use $couleur .= ... to build your string — Mark Baker

Instead of printing (echo), I think you want to store all data in a variable and write that data to file eventually. Otherwise you will see it when executing your PHP script, but it will not be written to file.

In your version, you're overwriting $couleur every iteration (as already pointed out by others), which explains why you only get the last array. You can append strings using the .= operator, which would make your code look like this, for example:

$colors = array (
    0 => array ("red", "black", "white"),
    1 => array ("yellow", "blue", "green"),
    2 => array ("orange", "grey", "pink"),
    3 => array ("purple", "brown", "clear"),
);

foreach ($colors as $value) {
    $couleur .= "<ul>";
    $couleur .= "<li>". implode ("</li><li>", $value) ."</li>";
    $couleur .= "</ul>";
}

$y = fopen ("list.html", "w");
fwrite ($y, $couleur);

Note that this provides you with four unordered lists. I'm not sure if that is what you want; you could also make one long list by moving the <ul> tags outside your loop:

$couleur = "<ul>";
foreach ($colors as $value) {
    $couleur .= "<li>". implode ("</li><li>", $value) ."</li>";
}
$couleur .= "</ul>";
