PHP - Search For Values Using Substr And Explode

I have a directory list using variables Folder/ and sub folders with /Folder/, what i need to do is replace the beginning slash if there is one. I'm using a recursive command and if i use substr for example:

subtr("$variable", 1); it will always remove the first character. What I need is an if statement or something to check to make sure it is a slash.

ok so i wan to use substr but i gives me Warning: substr() expects parameter 2 to be long, string given in C:\xampp\htdocs\ede\index.php on line 48

here the code

Code: [Select]
<?php
include "staff/scripts/connect.php";

$query = mysql_query("SELECT * FROM headlines ORDER BY id DESC LIMIT 3");
$rows = mysql_fetch_assoc($query);

$author = stripslashes($rows['author']);
$date = stripslashes($rows['date']);
$picture = stripslashes($rows['picture']);
$headline = stripslashes($rows['headline']);

mysql_close();
?>
<h2 class="boxtitle">Latest Headlines</h2>
<?php do{ ?>

<div id="boxhome">

<img src="staff/headlineimg/<?php echo $rows['picture']; ?>" width="100px" height="90px" class="boximg"></img>
<div class="boxtitle1">
<font color="#A61E0A"><strong><?php echo $rows['title']?></strong></font><br>
<?php echo substr(0,$headline,6)?>
</div>

</div>

<?php }while($rows = mysql_fetch_assoc($query))?>
</div>

what im trying to d is substr a table name just to get the fisrt character so i can use it as an AS...example

FROM news AS n


$table = "news";
$as      = substr($table, 0, 1);


sigular named tables are fine...but if the table is named something like this news_comments and have many underscores i want it to return nc...what is the best way to achieve this please?

Is it possible to get substr to end on a word boundry instead of halfway through a word?


Code: [Select]
$txt = "The cat goes splat on my bumper mat";
echo substr($txt, 0, 120); //this can be around 12 chars so doesnt need to be exactly 12 chars

$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?)

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.

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?

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?

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

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!

$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";
