I have an SMF website and i'm actually trying to get some header information which includes the title of a particular thread, the url but i've been finding it difficult to get the unique link affixed to the url using PHP.
Here's the url: http://example.com/index.php?topic=6449.msg6858
I'm actually looking for a way to extract the number 6449, I've tried to use the php GET function but it doesn't work.
$parts = explode('.', $_GET['topic']);
echo $parts[0];
// PHP 5.4+
echo explode('.', $_GET['topic'])[0];
See it in action
This would work, too
echo (int) $_GET['topic'];
See it in action
You want to use a combination of substr and strpos (to find the first occurence of a period)
$number = substr($_GET['topic'], 0, strpos($_GET['topic'], '.'));
// 6449
$arr = array();
if (preg_match("/([\\d]+)([.]{1}msg[\\d]+)/", $_GET["topic"], $arr) == 1) {
echo $arr[1];
} else {
trigger_error("not found", E_USER_ERROR);
}

Hi all i am looking for a simple way to check if a string equals an url like this:
http://youtu.be/WWQZ046NeUA
To convert it to a proper youtube url like this:
http://www.youtube.com/watch?v=WWQZ046NeUA
If not to leave it alone, what's the simplest way to do it in php?
You can use this preg_replace call:
$u = 'http://youtu.be/WWQZ046NeUA';
$r = preg_replace('~^https?://youtu\.be/([a-z\d]+)$~i', 'http://www.youtube.com/watch?v=$1', $u);
str_replace should work wonders.
$url = ''; //url you're checking
$ytshorturl = 'youtu.be/';
$ytlongurl = 'www.youtube.com/watch?v=';
if (strpos($url,$yturl) !== false) {
$url = str_replace($ytshorturl, $ytlongurl, $url);
}

I want to remove a particular match of characters from a string.
For example i have strings;
topics-p10-new-model-cars
topics-p20-new-model-cars
topics-p30-new-model-cars
topics-p40-new-model-cars
Then i need the results as,
topics-new-model-cars
topics-new-model-cars
topics-new-model-cars
topics-new-model-cars
That means i want to remove p10-,p20-,etc..
.Those are the page numbers. It may be any number..
How can i do this..? Thanks in advance
Try this:
$result = preg_replace('/\-p\d+/', '', $string);
Note: I'm assuming that the string format does not change (I mean this [topics-p10-new-model-cars]). If my assumption is right.
Then you can do this
if (textBox1.Text.Contains("-p10-"))
{
//topics-p10-new-model-cars
String[] splited = textBox1.Text.Split(new char[] {'-'});
String rString = String.Format("{0}-{1}-{2}-{3}",
splited[0],splited[2],splited[3],splited[4]);
MessageBox.Show(rString);
}
//OR This method
if (textBox1.Text.Contains("-p10-"))
{
String result = textBox1.Text.Replace("p10-", "");
MessageBox.Show(result);
}
With 'preg-replace'::
For, example:
<?
echo preg_replace('/p[0-9]+\-/', '', 'topics-p10-new-model-cars');
?>

I have a string : http://www.mywebsite/456754567/531613490.htm?menu=contact
I want to get the value between "/" and ".htm". Here : 531613490
Any idea ?
if ( preg_match('~[^/]+(?=\.htm)~', $string, $matches) ) {
echo $matches[0];
}
Here's a demo: http://codepad.viper-7.com/5kjEj6
I don't know how flexible you want your script to be, but here's my try:
It always takes the last part of the path
It won't fail for http://www.mywebsite/456754567.htm/531613490.htm?menu=contact' as Joseph Silber's solution does.
<?php
$path = parse_url('http://www.mywebsite/456754567/531613490.htm?menu=contact', PHP_URL_PATH);
$pathParts = explode('/', $path);
$fullFilename = array_pop($pathParts);
// better use something like lastIndexOf(), this won't fail for 'xxx.abc.htm'
$filename = substr($fullFilename, 0, strpos($fullFilename, '.'));
var_dump( $filename );

if i output my URI i also get the folder in which it is located at.
echo $_SERVER['REQUEST_URI']; //outputs /abcgetoutofjail/admin.php?make_account
im on localhost right now, and the website is under folder in htdocs abcgetoutofjail
i need only admin.php?make_account
i need the last part of the url in any way
how can i achieve that with either another way of getting uri or using a string function to cut SERVER URI
function DescriptionAndTitle($uri)
{
echo $uri;
}
In Php, you can achieve this using explode & count function.
$uri = '/some-dir/yourpage.php?q=bogus&n=10';
$uri = explode('/', $uri);
$len = count($uri);
print $uri[$len-1];
To get the last part of a URL I usually do something like the following:
$url = parse_url($_SERVER['REQUEST_URI']);
$partsofurl = explode("/", $url['path']);
$partyouwant = end($partsofurl);
$needed_part = end(explode('/', $_SERVER['REQUEST_URI']));
I believe this is what you're looking for:
$dir = explode('/', dirname($_SERVER['PHP_SELF']));
$dir = '/'.end($dir);
echo $dir;

this is probably an easy question, but I am not really a coder. I maintain a website for a group I belong to, and there are some php forms. I am trying to enhance a form, and I have added this php code, which works (see below). My question is, how can I put this code into a loop so that it repeats 10 times, for "01", "02", etc., "10" strings (code below is for "01" of the series)? Thanks for any help.
//Clean up the Photo Title & Maker Name to remove non-standard chars and replace spaces with underscores and generate a suggested fliename
$photo_01_clean = str_replace(" ","75357",$photo_01_name);
$photo_01_clean1 = str_replace("#","at",$photo_01_clean);
$photo_01_clean2 = preg_replace('/[^a-z0-9]/i', '', $photo_01_clean1);
$photo_01_clean3 = str_replace("75357","_",$photo_01_clean2);
$photo_01_maker_clean = str_replace(" ","75357",$photo_01_maker_name);
$photo_01_maker_clean1 = str_replace("#","at",$photo_01_maker_clean);
$photo_01_maker_clean2 = preg_replace('/[^a-z0-9]/i', '', $photo_01_maker_clean1);

You'd require a for loop control structure. You can find tons of resources that would teach you how to do it. example
Var i;
For (i =1; i<11; i++)
