PHP - How Do I Remove A Dash On The End Of A String If It Exists?

Is there a way/function to not only remove <script>, <embed> tags etc but also remove the content within the tags so this:

"
some text
<script>
functionhere();
</script>
some more text
"

to this:
"
some text
some more text
"

In effect remove the whole tag and content within the tags? Havent been able to find anything online that works

Many thanks in advance.

Hi, i have a query string id=5&start=0 that i want to remove from the url and return the url without it. I am searching a cleaner way for doing it. Here is an example :

Before : http://www.example.com/?a=3&id=5&start=0
After : http://www.example.com/?a=3

Before : http://www.example.com/?id=5&start=0
After : http://www.example.com/

Before : http://www.example.com/?alpha=1&id=5&start=0&beta=2
After : http://www.example.com/?alpha=1&beta=2

Thank you

Hi,

Im looking at using a statement like this to remove all text characters from a string.

  $outgoing = substr_replace($incoming,"",-1); 

The string is a currency that has a currency symbol in the beginning of the string, like "R500.00"

I would like to remove the R, so it is just a numeric value...

Please can you help me with any ideas on how to get this going? Been reading so much and its all confused me too badly.

Regards,
Chris

Hi is there anyway to check a string for any instances of something like this
"(3)" where the number "3" could be any integer. So basically I want to search a string for any instances of a integer in brackets "(integer)" and remove it.


So my string was something like


$string = "String (2) string string string (7)"

function($string)


output would be "String string string string"

where there integers in brackets could be any number

I have sen this function before but can not remember what it is or how to code it. It allows you remove only defined characters from the end of the string. I am not looking to replace any occurrence anywhere in the phrase, just the end.

For example lets say I want to remove"ld!" from phrase "Hello World!" That function would return "Hello Wor"

Thanks

I have a form with some dropdownlist that get populated dynamically(depends on what the user chooses) with jquery and an xml file. In the form I have a button that takes the info and populates another form with the values of the ddl. I have coded script which populates the second form with jquery and the name of each input get dynamically added like so:

Code: [Select]
<input type="text" value="'+model+'" name="Model_'+model+'" id="'+model+'" readonly size="'+model.length+'" />
<input type="text" value="'+model+'" name="Model'+model+'" id="'+model+'" readonly size="'+model.length+'" />>
<input type="text" value="'+color+'" name="Color'+color+'" id="'+color+'" readonly size="'+color.length+'" />
<input type="text" value="'+part+'" name="Part'+part+'" id="'+part+'" readonly size="'+part.length+'" />
<input type="text" value="$'+price+'" name="Price'+price+'" id="'+price+'" readonly size="'+price.length+'" />
<input type="text" value="'+qty+'" name="Quantity'+qty+'" id="'+qty+'" readonly size="'+qty.length+'" />
<input type="text" value="'+total+'" name="Total'+total+'" id="'+total+'" readonly size="'+total.length+'" />

What I want to do is grab the name of the element and remove the underscore and everything else form rileft to right so I am left with just the word before the underscore. I tried using substr($key,0,-28) but that wont work since everything after the underscore will have a different length. I was wondering if there is a way i can keep everything before the underscore and remove the underscore and everything after that.
Thanks in advance for any input I get.

I'm trying to remove a dash at the end of a title, for the times when a dash appears there (which isn't always).

Since my titles are always different lengths, I don't think substr will work.  How can I code the following... 

If $title ends with '-', replace with ''

Thanks!

Hello Everyone,

I have a PHP code that reads data from db table. Then it converts it into JSON and show it. However if data table field has - or so then it gives json error.

For e.g.

if($num > 0){
			while($res = mysqli_fetch_array($query)){
				
				$NDate = $res['NDate'];				
				$Summary = substr($res['Summary'],0,256);				
				
				/* CREATE ARRAY FOR SHORT TERM NEWSLETTER */
				$newsletters[]=array('newsletter'=>array("RecID"=>$SNo,"Summary"=>$Summary));
				
			}
			/* JSON OUTPUT*/
			$json = array("AuthOK" => 'True',"newsletters"=>$newsletters);
	
header('Content-type: application/json');
echo json_encode($json);

How to solve the issue ?

Regards,
GR

Hi,

I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads.  Here is uploadify.php as it currently looks:

Code: [Select]
<?php
session_name("MyLogin");
session_start();

$targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root

if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name'];

// Validate the file type
$fileTypes = array('m4a','mp3','flac','ogg'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);

if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}

echo $targetFolder;

?>
I added Code: [Select]
echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'.  For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'.  The folder for username exists, with correct permissions, and when I manually enter Code: [Select]
$targetFolder = '/songs/nick';all works fine.  Which strikes me as rather strange.  I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string.

Any help would be much appreciated.  It's the last issue with a website that was due to go live 2 days ago!

Thanks,

Nick
