PHP - Apply Trim On Whole Array?

I'm using the following code to attempt to strip white space from my search results:

Code: [Select]
while($row = mysql_fetch_assoc($rs)) {

trim($row['Name']);
trim($row['Address']);
trim($row['City']);
trim($row['State']);
trim($row['Zip']);
trim($row['Phone']);
 
 
echo "<td>" . $row['Name'] . "</td>";
echo "<td>" . $row['Address'] . "</td>";
echo "<td>" . $row['City'] . "</td>";
echo "<td>" . $row['State'] . "</td>";
echo "<td>" . $row['Zip'] . "</td>";
echo "<td>" . $row['Phone'] . "</td>";
echo "<td>" . $row['Type'] . "</td>";

Obviously, I'm leaving out a ton of code, but the important part is that it's not stripping the white space.  Things like this make me want to pound spikes into my eyes, because there's just no logical way for me to work though this.  I'm extremely OCD, and so if code doesn't work the way the documentation states, I freeze.   

I also tried (as per another tutorial example) setting a second variable trimming it, and using the second variable in the Echo, like so:

Code: [Select]
$Tname = ($row['Name']);
echo "Blah blah blah" . trim($Tname);

 That didn't work either.  It's simply NOT removing the white space, despite the fact that the entire description of what "Trim" does consists of "removes white space."  It boggles my mind.  Am I supposed to sacrifice a goat first or something?

BTW, if I go in and edit the database manually, I can strip out the spaces by hand, and everything works fine.  But it seems to me like the Trim command is supposed to exist to make it so that I don't have to do that.   The only thing I can guess is that for some reason the contents of the DB aren't being seen as Strings, even though they are, in fact, Strings.  I'm able to maniupulate them as Strings everywhere else in the code.  Just not here.    Does anyone know what I did wrong?
Thanks!

ive used trim to get rid of the end of a a string and it takes an extra character off it anyone can help please

echo $model_name       = trim($class_name, "_Model");
result:  Leagu

im want it to return: league

Sorry if this has already been solved. Also, I apologize if this is an amateur question...

I have a simple form and a script to do some validating of user data, among other tasks.

One part of the script is intended to verify a birthday.

Code: [Select]
$x = $_POST['x'];
$x = trim($x);
According to the php.net manual, trim() is supposed to remove whitespace before and after a string. My intent by using trim() is to determine if someone tried to skip the birthday field. I have other validation running on the value of $x, but I wanted trim() to remove whitespace.

However, the value of x, which in this case is expected to be numeric, such as 12 for a month, ends up being 1. This happens with any 2-digit number that a user might enter into the form field for x. The second number is always removed.

Any insight into why trim() removes the second number, 2 in the above example, leaving only a "1" as the value of $x, would be very greatly appreciated.

Thanks in advance.

Hello,

I have been messing around with this and can't seem to figure out what I'm doing wrong.  I'm pretty new to php, so it might be something silly.

Original code:
Code: [Select]
$a1=mysql_result($result,$i,"question"); //Question
$a2=mysql_result($result,$i,"answer"); //Answer
$a3=mysql_result($result,$i,"submission_id"); //submission id
$a4=mysql_result($result,$i,"category"); //submission id

echo "<a name=\"$a3\"></a><strong>$a1</strong>$a2";

Prints:

Question

Category

What I want is:

Question
Category

I have tried using the trim functions but nothing seems to help:

Code: [Select]
$a1=mysql_result($result,$i,"question"); //Question
$a2=mysql_result($result,$i,"answer"); //Answer
$a3=mysql_result($result,$i,"submission_id"); //submission id
$a4=mysql_result($result,$i,"category"); //submission id
$a1 = rtrim($a1);
$a2 = ltrim($a2);

echo "<a name=\"$a3\"></a><strong>$a1</strong>$a2";
Ideas?

i have a function that trims all post data

$trimmed = array_map('trim', $_POST);

                )


it gives me an error saying

An error occurred in script 'C:\xampp\htdocs\admin\create_listing.php' on line 23: trim() expects parameter 1 to be string, array given

Hello,

I am trying to use the php function string substr ( string $string , int $start [, int $length ] ) to remove trailing zero's in the DB from the price displayed on the page.

Currently using the code below I get this for output - $27.9500

<?php echo $row['prodprice']; ?>

I would like to get this $27.95.

So I tried using the string substr ( string $string , int $start [, int $length ] ) like this -

<?php echo substr("$row['prodprice']",0,5); ?>

but I receive t string errors and such using variations of this.

Can someone please explain to me what I am doing wrong and give me some pointers on how to fix this?

Thanks

Hi   Using: echo $row['columnname'];   How can I strip off data from the above echo? The column always begins with 'Local/' then 3 digits then other unwanted data, lke 'Local/567@context-0000461d;1'. It would be ideal to just display '567'.

$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

Code: [Select]
    <label for="first_name">* First Name </label>
   
    <input type="text" name="first_name" maxlength="64" value=<?php echo formatPhone(clean_input($_POST['first_name']); ?>>
I have a form where I want to enter a first name. I want the fields to take only alphabets(no numbers). Also when a user enters something like John                   Doe separated by multiple white spaces, I want it to separate the two words only by a single space. I am not sure how this is done in php.

Hi - wondering if someone can give a little guidance:

Why doesn't this trim the whitespace out of the string postzip?

trim(strtoupper(((isset($_POST["postzip"]))?$_POST["postzip"]:"")))

Thanks

Is there a way to trim everything off in front of the last backslash in the string?
Code: [Select]
$trimFile = $fList[$i];
Example:

In this path:
\\\\myftp/downloads/tom/work/word_docs\\legal\test.pdf

I only want to display test.pdf.

Thanks,

Jake

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

Sorry, I tried to understand the regular expressions but can't figure out the following.  How do I take this string

/direct1/showtable.php

and make it
showtable.php.

In other words strip out the /direct1/

Once I see how this is done I can apply it to other examples.  Thanks!
