I get this error on my homepage  :
Warning: implode() [function.implode]: Invalid arguments passed in /home/shqip1/peqini.com/wp-content/themes/sportpress/functions/wpzoom-widgets.php on line 1469

This is the code to modify

Hi, I'm trying to explode an array into a multidimensional array using <br /> tags as splitters but just can't get the syntax right! I can do lines of the array one by one, but not the whole lot at once. I'd really appreciate a quick example of an explode inside an array.

$myarray looks something like this with print_r:
(
    [0] => 
    [1] => some_html<br />some_html<br />some_html<br />
    [2] => some_html<br />some_html<br />some_html<br />
    [3] => some_html<br />some_html<br />some_html<br />
)

and I want to turn it into this:
(
    [0] => 
    [1] =>
     [0]some_html
     [1]some_html
     [2]some_html
    [2] => 
     [0]some_html
     [1]some_html
     [2]some_html
    [3] =>
     [0]some_html
     [1]some_html
     [2]some_html
)

I've tried this
$myarray = explode ("<br />", $myarray);
but it doesn't work …

It doesn't matter too much if there's are a few empty lines in the array from the final <br /> tags.

Many thanks, as ever, for any help.

My error is 'Warning: implode() [function.implode]: Invalid arguments passed in /home/definiti/public_html/contact.php on line 73'

Im not sure how to fix this error, as I looked online and it says that my implode() has the right layout too it..

Line 73 in my code (I took the HTML code out) is this line;

Code: [Select]
$message = implode("<br>\n", $messages);

My whole code is;

 I am using a PHP class (it is attached) for Google Analytics that I got from this link below:
http://www.acleon.co.uk/?p=173

Unfortunately, it appears the Class has a PHP error:
Warning: implode() [function.implode]: Invalid arguments passed in Galvanize.php on line 114 and line 181.

This is line 114:
setcookie('__utmc', implode('.', $this->UTMC), 0, $this->CookiePath, $this->getDomain());

Here is line 181:
$urchinUrl .= '&utmcc=__utma%3D'.implode('.', $this->UTMA).'%3B%2B__utmz%3D'.implode('.', $this->UTMZ).'%3B';

I did not see UTMC and UTMZ declared anywhere in the Class.

The class file is attached. Thanks for your help in advance.

Hello,
I'm just a beginner (and french sorry for my language) : have some pb with my little implode function.
It's Running well on my local webserver (MAMP - PHP PHP Version 5.2.17) but when tested on ovh server (PHP4) show this error :
Warning: implode() [function.implode]: Invalid arguments passed in /homez.xx/myPathHere/entete.php5 on line 6
I understand
1/ that one argument is missing but don't find the right syntax
2/ I have tried to turn this file on php5 with this extension (ovh is under php4)
Here is my code in page defining the value and where stay my query (entete.php5)

<?php
if (isset($theme)) {
   $t = implode(',',$theme);
   $lien = "aide.php5?theme=".$t;
   $aide = '<a href="'.$lien.'">'.$onglet[0].'</a>';
} else {
   $aide = "";
}
?>


Here is my code in page which show result (aide.php5)

$t = explode(',',$_GET['theme']);
$n = count($t);
if ($n == 1)  {
   $where = "id = ".$t[0];
} else {
   $where = "id = ".$t[0];
      for ($i=1;$i<$n;$i++) {
      $where .=  " OR id=".$t[$i];
   }
}
Hope someone kindly help me : thanks in advance

This is my code for displaying images from a folder:    function generate_img ($imagepointer, $imageornot){
 if($imageornot == 1){
 $var = getcwd();
 $dirlocation = $var."\\imageuploads\\".$imagepointer;
 $files = array_diff(scandir($dirlocation), array('..', '.'));
 foreach ($files as $image){
 $data[] = array('label' => '<img src="/imageuploads/'.$imagepointer.'/'.$image.'" alt="thumbnail"> <br/>');
        };
    return $data;
    }
    else {
    return FALSE;
    }
 }   I'm using it with print_r:               <p><?php print_r(generate_img($imagepointer, $imageornot)); ?></p>     Working ok, but obviously not good for a live site. Is implode() a good idea in this situation? And how would I use it?

Appreciated.    

Not sure if this is right.  I can't get it to insert my record.  Can someone please tell me if I'm doing it right?   cus_functions.php

function dbRowInsert($table_name, $form_data)
{
global $conn;
   
    $fields = array_keys($form_data);

    $sql = "INSERT INTO ".$table_name."
    (`".implode('`,`', $fields)."`)
    VALUES('".implode("','", $form_data)."')";

       return mysqli_query($sql);
}

process.php

 include("new_db.php");
 include("cus_functions.php");
 
 $do=$_GET['do'];
 
 if($do=='addpro'){
 
if(isset($_POST['submit'])){

$input = $_POST['title'];
$comp = '0';

$form_data = array('title' => $input, 'completed' => $comp);
 dbRowInsert('projects', $form_data);

}}

Can  anyone help me complete this script I can get it working with using an implode function, but for the purpose of knowledge I want to not use it.

I just want it to echo back the corresponding checkboxes, but I can't get the echoing correct, it echoes back array not the value?

Code: [Select]
<html>
<title>What do you want on your Tombstone?</title>

<body>

<?php

$Output_form = true;
if (isset($_POST['submit'])) 
{
if (empty($_POST['toppings'])) 
{ 

echo '<b>You forgot the toppings for your Tombstone.</b>';
echo '<br>';
echo '<br>';

} else {

echo '<p><b>This is what you are getting on your Tombstone: ';
(array)$_POST['toppings'];
echo $toppings;
echo '!';
echo '</p></b>';
$Output_form = false;
}
}

if ($Output_form)
{ 
?>

<form action="ProcessToppings.php" method="post">
<p><i><h2>What do you want on your Tombstone?</h2></i></p>
<p>
<input type="checkbox" name="toppings[]" value="pepperoni" /> Pepperoni<br />
<input type="checkbox" name="toppings[]" value="sausage" /> Sausage<br />
<input type="checkbox" name="toppings[]" value="mushrooms" /> Mushrooms<br />
<input type="checkbox" name="toppings[]" value="cheese" /> Cheese<br />
<input type="checkbox" name="toppings[]" value="olives" /> Olives</p>
<p>
<input type="submit" value="Make that Peet-Za!" name="submit" /></p>

</form>

Hi all!

This is probably fairly simple for someone who is used to dealing with arrays. I have an array of data(Parsed from an XML document) containing a string I would like to further split into another array.

The string is along the lines of:
"<name>":<value>,"ID":20251,"ID2":2300,"ID3":2000

How can I split the above into:
Array[<NAME>] => <VALUE>

Notes:
<name> changes often. depending on the query, it may have different <name> values.

I have been trying to do it with preg_split and got to:
Array ( => "<NAME>":<VALUE> [1] => "ID":20251)

but I need to split it further at ":". I tried a foreach, but I failed miserably.

Can anyone point me in the direction of better practice for arrays/preg_split? I have looked into the PHP documentation, but it is not enough for me.

Thanks in advance

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 have in ONE MySQL database row a string of ID's like this:

Name of Row: Values: Post IDs 10 14 52 37
And now I want to fetch those ID's explode them (by the space) and then use them as an array, like this:


$array[] = explode(" ", $query);

echo $array[0]; // 10
echo $array[1]; // 14
echo $array[2]; // 52


Is this possible, if yes how can I do this?
