@NogDogDec 06.2010 — #It's OK to name a variable $array, though not very good practice since it conveys absolutely no meaning (well, other than that it's supposedly an array ? ). If you're just looking for a quick and dirty way of outputting an array, print_r() will work, but if you are echoing it you should add the 2nd optional argument with a true value.
If you just want the values, you can implode() the array:
If you need the keys, too, foreach() can be your friend:
Array Outputting
Here’s my problem my script works so far untill it trys to output an array then it just stops and shows nothing.
[code=php]
$action = $_GET[‘action’];
echo “Photo editing is undermantinace please check back later”;
$albumSql = “SELECT * FROM `PhotoAlbums` WHERE `ID` = ‘$user_id’ AND `AlbumID` = ‘$action'”;
$albumResults = mysql_query($albumSql,$conn);
$array = mysql_fetch_array($albumResults);
echo”<form method =’post’> Form Here $action $array</form>”;
this works fine but once i add this line of code
[code=php]print_r($array);
then it just stops working and nothing is echoed before it
and i don’t know why.

echo "blah blah" . print_r($array, 1) . "yadda yadda";
[/code]If you just want the values, you can implode() the array:
[code=php]
echo "<h2>Here it is:</h2><p>" . implode("<br />n", $array) . "</p>n";
[/code]If you need the keys, too, foreach() can be your friend:
[code=php]
echo "<ul>n";
foreach($array as $key => $value) {
echo "<li><strong>$key:</strong> $value</li>n";
}
echo "</ul>n";
