PHP - Question Regarding Substr

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.

Ok, I'm stumped on this one.

I'm looking to strip html code from the following output:

Code: [Select]
<?php echo substr($f7,0,60); ?>
How do I insert the strip_tags into that statement?

$num = 27;

$first_digit = substr($num, 0);
$last_digit = substr($num, -1);

echo $first_digit; //this returns 27
echo $last_digit; //this returns 7

In the above example why is the first echo statement returning the full number whereas the second returns the last digit?

(I know why the last digit is returned in the second the real question is why wouldn't the first return 2?)

I have front page and page for news, and i wonna to set, on front page to show news but only 100 characters, and on news page to be all text, i done that with substr($news, 0, 100); but i have proble, when i have in $news text like this:
Code: [Select]
Hi everyone.
<b>Bold</b>now, subsrt count <b> and </b> like characters, how can i escape that <b> </b>, <u> </u> and other?

Actually.. I'm assuming I use substr, but feel free to correct me if there's a better way. 

I have an ever changing list that I need to knock the from numbers off of.  The numbers can be different lenghts, such as..

1. item number 1
12. item number 12
101. item number 101

How do I remove the number, period and blank space for each item, since the length of the number may always differ?

Thank you!

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

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?

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

when in a form, I wish to build a conditional that if the response to a radio button is a value of 2 (female), it will display an input requesting for users maiden name. If not 2 goes to the next input statement.

Here is code I was experimenting with:


<html>
<body>
<form action="" name="test"  method='POST'>
<input type="radio" id="sex" value=1 checked><label>Male</label>
<input type="radio" id="sex" value=2><label>Femaleale</label>

    <?php
    $result = "value";
    if ($result == 2)
        echo "<input type='int' id='gradYear' size='3' required>";
        else
        echo "Not a female!"
    ?>

    <input type="submit" value="GO">
</form>
</body>
</html>


The code passes debug, however, Not a Female is displayed.

My question is - Can I do this and if so, what value do I test against id='sex' or value. I tried each one but gave the same results. I realize that $_POST[sex] would be used after the submit button is clicked. But this has me stumped.

Thanks for the assis in advance.

I am trying something simple, creating some horses and making them race using OOP, creating them is easy, how can i find out which one "won" based on the highest total. Here is what i got so far

Code: [Select]
<?php

class Horse
{
   public $strength;
   public $speed;
   public $agility;         

        public function create($name,$age,$odds){
            $this->name=$name;
            $this->odds=$odds;
            $this->strength=(rand(50,200) * $this->odds - $this->age);
            $this->speed=(rand(100,400) * $this->odds - $this->age);
            $this->agility=(rand(150,250) * $this->odds - $this->age);
            $all=array(0=>"$this->strength",1=>"$this->speed",2=>"$this->agility");
            echo "<b>$this->name</b> has a strength of <b>$this->strength</b>, a speed of <b>$this->speed</b> and agility at <b>$this->agility</b>. --- <b>".array_sum($all)."</b><br>";
        }
}

$mix=rand(2,6);
$a=new Horse;
  $a->create("Dave",  2, $mix);
  $a->create("Dude",  3, $mix);
  $a->create("Evan",  3, $mix);
  $a->create("Jill", 15, $mix);
  $a->create("Flex", 10, $mix);

?>

I cant figure out a way to find out who had the highest total, i would love to know what i am doing wrong.

i am trying to understand, how a site like ebay can display content and be case insensitive?
for example:
  The original url:

http://www.ebay.co.uk/itm/Toshiba-Satellite-C50-AMD-E-Series-1-4GHz-Dual-Core-15-6-Inch-500GB-2GB-Laptop/151458954958

the above works fine and go to the intended page.

user editing the browser url into lowercase :

http://www.ebay.co.uk/itm/toshiba-satellite-c50-amd-e-series-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958

random uppercase and lowercase.

http://www.ebay.co.uk/itm/toshiba-sateLLite-c50-aMd-e-sERIes-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958

both the urls above also work fine and go to the intended page.   How can such a thing can work? it is supposed to throw an error such as page not found and the like?

any thoughts welcome.
