PHP - Newb: Trim And Strtoupper

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!

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.

Hey


Is there a way to trim the print_r($array); so its completed and void of white space?


It prints like this:



Code: [Select]

Array
(
    [0] => Array
        (
            [id] => 10
            [f] => data/tiles/image.png
        )
)

But I want it to be compressed like this:


Code: [Select]
Array([0]=>Array([id]=>10[f]=>data/tiles/image.png))
This is then to be stored in the database, so any compressed possible is a plus in this situation.


Any ideas?

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

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.

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

Is there a way to apply the function trim() on a whole array, instead of applying it to the individual input fields one by one?

Here's the code:

$blurb1_title = array ( 
$_POST['blurb1_title1'], 
$_POST['blurb1_title2'],
$_POST['blurb1_title3'],
$_POST['blurb1_title4'],
$_POST['blurb1_title5']
);

$blurb2_title = array ( 
$_POST['blurb2_title1'], 
$_POST['blurb2_title2'],
$_POST['blurb2_title3'],
$_POST['blurb2_title4'],
$_POST['blurb2_title5']
);

$blurb3_title = array ( 
$_POST['blurb3_title1'], 
$_POST['blurb3_title2'],
$_POST['blurb3_title3'],
$_POST['blurb3_title4'],
$_POST['blurb3_title5']
);



All those $_POST variables are input fields, and I would like to apply trim() to them so the spaces get removed.

Is there an efficient way to do it without having to apply it all individually, if yes, what would be the correct syntax?



[php]

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

Hello   I am Importing CSV file using PHP but it imports with blank lines and white spaces    please guide how to recover this      i am attaching both files for reference   awaiting your valuable reply Attached Files  dayseatchart.php   4.46KB   1 downloads

Ok, this was driving me nuts.  I think I found the cause, but need help fixing it.  I have a bunch of answers in a MySQL database in the form of...

Miami Heat/heat/miami
Orlando Magic / orlando/ magic
etc.
etc.

*Notice how sometimes there are leading or ending spaces (i.e there is a space before "magic" but NOT a space before "miami")...

I run this code to bring back the answers data (all acceptable answers) in an array.  I then look for the user entered answer ($userinput, which has trim and strtolower run on it) in the array.

Using this code below, the answer IS found if $userinput is any of the Miami Heat options, but it is NOT found if it's any of the Orlando Magic options.  The only difference is the fact that there are spaces in the Orlando Magic stuff.  Apparently, the trim() function is only removing space from the beggining and end of the ENTIRE string.  But I need to trim() each item in the array. How can I do this?  Seems like it should be easy but can't figure it out.

Code: [Select]
$sql = "SELECT * FROM answers
WHERE quizid = $quizid";
$result = mysql_query($sql, $connection);
if (!$result) {
die("Database query failed: " . mysql_error());
} else {
while ($getanswers = mysql_fetch_array($result)) {

$array = explode("/", strtolower(trim($getanswers['answer'])));

if (in_array($userinput,$array)) {
echo "the answerid = " . $getanswers['answerid'] . "<br>";
} else {
echo "the answerid is not found= <br>";
}


}

}

I have a Form with 10 Questions that a User can choose to answer.

I am trying to store the "Answers" into an array like this...
Code: [Select]
<!-- Question 1 -->
<label for="question1">1.) Why did you decide to start your own business?</label>
<textarea id="question1" name="answerArray[0]" cols="60" rows="8"><?php if (isset($answerArray[0])){echo htmlentities($answerArray[0], ENT_QUOTES);} ?></textarea>
<?php
if (!empty($errors['question1'])){
echo '<br /><span class="error">' . $errors['question1'] . '</span>';
}
?>
<br />

<!-- Question 2 -->
<label for="question2">2.) What advice would you share with others on what NOT to do?</label>
<textarea id="question2" name="answerArray[1]" cols="60" rows="8"><?php if (isset($answerArray[1])){echo htmlentities($answerArray[1], ENT_QUOTES);} ?></textarea>
<?php
if (!empty($errors['question2'])){
echo '<span class="error">' . $errors['question2'] . '</span>';
}
?>
<br />


The problem is that when I process the Form, this code is causing issues...
Code: [Select]
if ($_SERVER['REQUEST_METHOD']=='POST'){
// Form was Submitted (Post).

// Initialize Errors Array.
$errors = array();

// Trim all form data.
$trimmed = array_map('trim', $_POST);

I get this error...
Code: [Select]
Notice: Array to string conversion in /Users/user1/Documents/DEV/++htdocs/05_Debbie/members/create_thoughts.php on line 58
Call Stack
# Time Memory Function Location
1 0.0014 93944 {main}( ) ../create_thoughts.php:0
2 0.0716 102640 array_map ( ) ../create_thoughts.php:58

How can I either fix my code or change things to do what I need?

Thanks,


Debbie

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!

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

Discovered something very strange with trim() and numbers with leading zeros.

Code: [Select]
<?php
$number = 0456;
echo trim($number);
?>

That ouputs 302. How the heck does 0456 trimmed turn into 302? Is this a bug?
