PHP - How Do I Use Substr To Remove Numbers Only?

If I were to split this variable in half:

Code: [Select]
$one = none:0

Using this bit of code:


function cut($string)
{
        $string = substr($string, strrpos($string, ':'));
$string = str_replace(':', '', $string);

return $string;
}


Is it possible to get the part of the string that comes after the : in $one?

EDIT: I suppose I could add another : at the end of the string and get the position of the last occurrence, but I'm curious if their is an easier method.

Hi guys,

I would like to ask your help on how to trim the output (title). for example the title is "php freaks rocks" it should be "php freaks..."

Thanks..

Hello,   A not so experienced PHP-user here. For my school assignment, I have to make the following:   "Stolwijkstraat 8" has to be shortened into SW with use of SUBSTR and STRTOUPPER.    My question: 1. How can I be able to use SUBSTR and STRTOUPPER in the same line? 2. How can I be able to remove everything in the line ''Stolwijkstraat 8", on behalf of ''S'' and ''w''?   A quick response would be greatly appreciated.   Kind regards.

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,
I need to sort variables in groups of up to 15 and put it in an array. For example:
$exstract['center_tabOpBody_0'] =5
$exstract['center_tabOpBody_1'] =6
$exstract['center_tabOpBody_2'] =8
$exstract['center_tabOpBody_3'] =1


Should yield:
ARRAY(
          = center_tabOpBody_1,center_tabOpBody_2,center_tabOpBody_3 // <-----15 [1] = center_tabOpBody_0 //<----5
)

Is there some simple function do do the "efficiency" sort?

Thanks,

this is the piece of code

   $cookie = explode("\r\n", $raw_value);
   if (substr($cookie, 0, == 'Cookie:') {
      return substr($cookie_split_sent, ;
   }
return "";
}

What I need this code to do is get the raw value from and xml file and split it and store it in $cookie. Next I want to extract only that part of text which begins after the word "Cookie". If there is any value return the value to the function if not return blank. However am getting the following error

Warning: substr() expects parameter 1 to be string, array given in

I know its expecting a string value. But am heading at a dead end now. Am pretty new to php. Any help would be highly appreciated

Here's my echo statement for displaying comments by users.  I want to add a substr (); function to limit the amount of characters of the $comment field. That way if a user makes a long comment it doesn't push the page down.

I tried putting it after the echo ();  but that didn't work. I also tried putting it before $comment and that didn't even work. I know that if I make two separate echo statements, this can be done, but the field "$comment" is displayed within a table that is part of the original echo statement, so what do I do?

Hi,

When i am getting the part of the text using the function substr, am getting this kind of problem , (text in the end not printing properly) how to solve this.

تسر مؤسسة مهارات التقنية ومؤسسة اشبكة الثنائية ان تطلع جميع عملاءها بإصدار نظام تاتش لإدارة الموقع الالكترونية من يوم السبت ا�


This is the code am using
$sub_string_content = substr($temp['News_Content'],0,300);



Thanks,

$to = $notifyemail;
$from = "xxx@xxx.com";
$subject  = "[ $rawticket ] Random $notifytype Notification";

Currently the output is an email with a total of 15 numbers,
i.e. SUBJECT:  [ 000000001718989 ] Random $notifytype Notification

I want to remove the 0's

Would something like this work or is this not possible?

"[ (substr($rawticket,9)) ] Random $notifytype Notification";

First problem fixed.
My second problem is if the result is 0X.XX,0 or 0X.XX,1 I would like to remove the first 0
The X.XX are numbers, but the 0 is not always there.

Can anyone help please
Thanks

can you have something like..

echo $whatever;

this putput
1.2

can you split this number so the first integer will be in $val"(1)" or whatever and the second integer after the "." will be in $val2"(2)"
