PHP - Php Displaying Blanks.

I have strings that can look like this "monkeys / cats/ dogs / snakes".

I have code that breaks the items apart and puts each as a separate item into an array, like this (where $getstring['thestring'] equals strings like the example given above)...

Code: [Select]
$array = explode("/", strtolower(trim($getstring['thestring'])));
foreach($array as $k=>$v)
{
$array[$k] = trim($v);
}
}
My question is how can I add some code so that if there are ever instances where there is nothing between  each /, it does NOT put that "blank" into the array?

For example, if a string was something like "monkeys / cats/ / dogs/ eagles / / snakes", the code now would create two array items that are essentially "blank" because there were two consecutive slashes, two different times in that same string.

These strings are entered by users so there is definitely a possibility they make a mistake such as above so I need a way to weed out those mistakes (i.e. the blanks).

Any ideas for easiest way to find the "blanks" and NOT have them in the array?

I'm trying to grab something on a different page with the layout:

Code: [Select]
0 day, 10 hours, 35 min, 59 sec
My code to display this information on another page is:

<?php
$page_contents = file_get_contents("http://www.mysite.com");
$matches = array();
preg_match('/([0-9,]+) day, ([0-9,]+) hours, ([0-9,]+) min, ([0-9,]+) sec /', $page_contents, $matches);
echo $matches[0];
?>


Why is it displaying nothing?

Quick background... I bought an auction program with plenty of bugs. Todays bug that I can't figure out is that it is displaying a - (dash) when I would prefer it to display 0 (zero) in instances of "total fees due" or in the "fee chart" if it's a flat fee of 0.  0% works fine.

The code related to it is spread out on a handful of files but I think it's mostly related to the following.

   
if (is_array($setup_fee))
    {
    foreach ($setup_fee as $key => $value)
    {
    if ($value['amount'])
    {
    if ($value['calc_type'] == 'flat')
    {
    $output['amount'] += $value['amount'];
    $fee_display = $this->display_amount($value['amount'], $this->setts['currency']);
    }
    else if ($value['calc_type'] == 'percent')
    {
    $output['amount'] += $this->round_number($item_details['start_price'] * $value['amount'] / 100);
    $fee_display = $value['amount'] . '%';
    }

    if ($item_relist)
    {
    $output['amount'] = $this->round_number($output['amount'] - $output['amount'] * $this->fee['relist_fee_reduction'] / 100);
    }

    $output['display'] .= '<tr class="c1"> '.
    ' <td width="150" align="right"><b>' . GMSG_SETUP_FEE . ':</b></td> '.
    ' <td align="left" nowrap colspan="2"><b>' . $fee_display . $value['display'] . '</b></td> '.
    '</tr> ';

I'll really really appreciate the help.

Okay, so I am trying to display players usernames and kills and deaths from my highscores page and I have different div classes set for each block This is my code:

<div id="table">
<div class="tr ttl">
<div class="col st1">Rank</div>
<div class="col st2">Username</div>
<div class="col st3">Rating</div>
<div class="col st4">Deaths</div>
<div class="col st5">Kills</div>
</div>
<?php
if($_GET['skill'] == 0) {
$skill = $_GET['skill'];
$page = ($_GET['page']-1);
$limit = RESULTS_PER_PAGE*$page.', '.RESULTS_PER_PAGE;
$limitt = RESULTS_PER_PAGE*$page;
$query = "SELECT * FROM hs ORDER BY `elo` DESC LIMIT ".$limit."";
$result = mysql_query($query);
$counter = 1;
while ($fetch = mysql_fetch_assoc($result)) {
echo '<div class="tr normal ftr rd1">
<div class="col st1">'.($counter+$limitt).'</div>
<div class="col st2"><a href="?user='.$fetch['username'].'">'.$fetch['username'].'</a></div>
<div class="col st3">'.number_format($fetch['kills']).'</div>
<div class="col st4">'.number_format($fetch['deaths']).'</div>
<div class="col st5">'.$fetch['elo'].'</div>
</div>
';
$counter++;
}
}
?>

See where it says echo '<div class="tr normal ftr rd1">    I'd want it to print out like this:  (tr normal ftr rd1) for the first one, (tr normal ftr rd2) for second one and (tr normal ftr rd3) for the 3rd one. Then (tr normal) and (tr odd normal) for the rest Can anyone help me out here?  

Hi.

I have this code which input data to the database.
Code: [Select]
<?php


include("connect.php");

echo $date = date("Y-m-d H:i:s");
echo "\n <br />";

echo $date2 = date('Y-m-d H:i:s', strtotime("+20 seconds")); 
mysql_query("UPDATE users2 SET date2 = '$date2'");


$query = mysql_query("SELECT date2 FROM users2");
$numrows = mysql_num_rows($query);

if ($numrows != 0)
{
while ($row = $mysql_fetch_array($query))
{
$date_final = $row['date2'];
}
}
echo $date_final;
?>
Variable date2 is stored as timestamp. Now i want to display this two variable on the web, but this code doesn't work. Why? Thank you.
