PHP - Accessing Object Value That Contains Whitespace.

$string = " hel lo ";

$string = rtrim($string);
$string= ltrim($string);

which trims the whitespace from the front and back, but how do i remove the middle space?

Thanks

Hi all

I need to remove the spaces in an uploaded file. I have tried str_replace and trim etc... but it doesn't work.

Here is my code:

Code: [Select]
move_uploaded_file($_FILES['image']['tmp_name'][$i], WEB_UPLOAD."/images/galleries/g".$gid."/".$_FILES['image']['name'][$i]) or die("Error uploading image ");

Thanks
Pete

hello everyone.   could you advise me on the structure of my code to check if it is correct:

RewriteRule ^/user/([a-z]+)/cake/([a-z\ .*A-Zx0-9-_]+)$ 

/cakes.php?userid=$1&cakebaked=$2

what i am trying to do is to add a - instead of a whitespace which appears in the url as %20.

How am i to do this either a php builtin function i am unaware about or something simple with regular expressions replacing

I need a way to remove whitespace (tabs,spaces,newlines,etc) and anything else that seperates <> tags such as

Code: [Select]
<td class="subject solvedbg">
<div>
<span id="msg_1">blah blah space   see
<a href="blahblah>
</div>
</td>
to

Code: [Select]
<td class="subject solvedbg"><div><span id="msg_1">blah blah space   see<a href="blahblah></div></td>
Thank you.

I have a Soup object in a Bowl object in a Microwave object.

The Microwave object has the methods:

receiveItem(Bowl $b)
cookItem(???)

I want the Microwave to be able to set the Soup->temperature but I'm not how to do that?

Make sense?

Hi guys,

I have xml that looks like:

<item>
<title></title>
<link></link>
<description></description>
<dc:date>2011-02-27T16:42:31-05:00</dc:date>
</item>


I can access title, link, and description just fine.  But how do I access a tag that has a colon?

I tried this:

Code: [Select]
$x = new SimpleXmlElement($content);
$entry = $x->item;

$entry->children('dc', true)->date;

Thanks for looking.

HEy Guys
Here is a snippet of an array:

SimpleXMLElement Object
(
    [report1] => SimpleXMLElement Object
        (
            [ReportHost] => Array
                (
                    => SimpleXMLElement Object
                        (
                            [HostName] => 192.168.2.34
                            [startTime] => Thu Dec 17 13:58:49 2009
                            [stopTime] => Thu Dec 17 15:13:13 2009
                            [netbios_name] => (unknown)
                            [mac_addr] => (unknown)
                            [dns_name] => (unknown)
                            [os_name] => (unknown)
                            [num_ports] => 2
                            [num_lo] => 0
                            [num_med] => 0
                            [num_hi] => 0
                            [ReportItem] => Array
which is printed using print_r($a)
now how can i access [HostName] => 192.168.2.34 in the $a array??
Thanks in advance

I am a part of an institue which has internal web pages. It also provides me with my web space with php servers. Now I know those internal web pages are available to the server. I want a code that can fetch those web pages and display it  in my web space. And whatever forms i fill or links i click it should do those on internal page and again return the new web page.

If $result contains the result of mysql_query, a select count distinct query, how do I access the count?  I've tried $result[0] to no avail and $result only returns the resource #.

Hi all,

I am still trying to figure what went wrong. It doesn't work over here.

The error shown was the {else} command
else {
      echo '<p class="error">There was a problem accessing your profile.</p>';
   }

I have attached my 4 sql tables for reference. Appreciate any advices....

Code: [Select]
<?php
$query3 = "SELECT ols.subject_level_id, sl.level_id, sl.subject_id, tl.level_name AS level_name, ts.subject_name AS subject_name " .
        "FROM tutor_overall_level_subject AS ols " .
"INNER JOIN tutor_subject_level AS sl USING (subject_level_id) " .
        "INNER JOIN tutor_level AS tl USING (level_id) " .
        "INNER JOIN tutor_subject AS ts USING (subject_id) " .
"WHERE ols.tutor_id = '" . $_GET['tutor_id'] . "'";


  $data3 = mysqli_query($dbc, $query3)
  or die(mysqli_error($dbc));

  if (mysqli_num_rows($data3) == 1) {

echo '<div id="panel4">';

echo'<table><tr>'; // Start your table outside the loop... and your first row
$count = 0; // Start your counter
while($row3 = mysqli_fetch_array($data3)) {
/*  Check to see whether or not this is a *new* row
If it is, then end the previous and start the next and restart the counter.
*/
if ($count % 5 == 0) { 
echo "</tr><tr>"; $count = 0;
}
echo '<td class="label">' . $row3['level_name'] . '</td><td>' . $row3['subject_name'] . '</td>';
$count++; //Increment the count
} 
echo '</tr></table><br/>'; //Close your last row and your table, outside the loop

echo '</div>'; //End of panel 4

} //End of if (mysqli_num_rows($data3) == 1)

else {
echo '<p class="error">There was a problem accessing your profile.</p>';
}

Hey everyone,
I'm creating a website which requires users to login. I didn't want to have to do my own crypto, so I basically created it with Wordpress. I'm at the point where I don't want to use Wordpress for the whole site--just the login system. So I was wondering how I can piggyback off the user management system of Wordpress while using my own script for the rest of the site. I know that Wordpress ends up storing passwords in the database as HMACs, for what that's worth.
Thank you,
Ryan

Can somebody help me what i'm  doing wrong? The value from database is not visible when using:
<?php
$artikel = new Artikel();
$content= $artikel->printArtikel();
echo $content;
?>


<?php
class Artikel {
                // db connection
protected $mydb; 

                // database value
protected $land;

public function __construct($artikelnummer = false)
{  // databaseconnection:
$this->mydb = new MyDB();

if($artikelnummer)
{
$this->load($artikelnummer); 
}
else // load everything from database.
{
$sql = "SELECT * FROM artikel";
$this->mydb->doQuery($sql);
$this->mydb->close();
}
}

public function load($artikelnummer)
{
$sql = "SELECT * FROM artikel";
$this->mydb->doQuery($sql);

if($artikel = $this->mydb->fetch())
{
    // i got a feeling there is something missing here, like query from database??
                }
$this->mydb->close();
}

public function printArtikel()
{
// return database value as table.
$html = "<table border='1'>";
$html .= "<tr>
<td>".$this->land."</td> 
                </tr>";
$html .= "</table>";
return $html;
}
}
?>


Other class are accessing extern. For example database connection with class MyDB.
please, can somebody correct my script??

Is it possible to have a class access another class it its parent directory without using a fully qualified name?  While the following script is not valid, it is how I would have thought it would be done should it be possible.  If it is not possible, I expect there is a good reason why one would not want to do so, and would appreciate your thoughts why that is so.  Thanks

Hi all,

I've tried to access the admin.php of the xcart installation he http://www.cleaningshopuk.com but it doesn't allow me to access it, saying that it's a 404 page not found error.

That page does in fact exist, but I think the issue might be something to do with a redirection. The site owner apparently clicked on something in the admin section (possibly https or something similar) but what can I do to avoid this issue without having to re install everything?

Thanks,

Neil

    I have the following code in zend:

  Code: [Select]
$arrErrors=array();
     if (!empty($this->post['submit']))
    {
    // Each time theres an error, add an error message to the error array
           // using the field name as the key.
          if (empty($this->post['client_name']))
      $arrErrors['client_name'] = "Please Enter Client's name as it appears in the carrier software";
    }
if i set $this->view->arrErrors=$arrErrors in the controller,
Can I access it as $this->arrErrors['client_name'] in the view?
