PHP - Extract Part Of A String

I just managed to login to a forum using curl, but then I found out I had to extract the session id before I could start posting. The session id is in a string like this:

sesc=b97b74351fde8dfbac7391af1f054de9

How do I extract the value b97b74351fde8dfbac7391af1f054de9 if I know that it comes righ behind "sesc=".

I think I am supposed to use strpos, but I don't know.

Hello,

Anyone know a way I could extract information from YouTube. If I have the URL for the video, how could I get the title, runtime, tags and so on into different strings?

    url = "http://www.youtube.com/watch?v=kMAI26FPeyM";


Thanks

Can anyone help me output "Zinfandel|Sauvignon Blanc" from "This very nice wine is produced in California and is made from Zinfandel and Sauvignon Blanc grapes."? Please also notice the case insensitivity. I prefer the output with capitals on first words.    I created the following code :

<?php 
$ds = "Riesling|Sauvignon Blanc|Zinfandel|Muscat/i";
$string = "This very nice wine is produced in California and is made from zinfandel and Sauvignon Blanc grapes.";

echo "This is the string to extract the grapes from : ";
echo $string;
echo "<br>";

echo "These are the grapes that need to be matched in a regular expression : ";
echo $ds;
echo "<br>";

$matches = array();
$search = preg_match_all($ds, $string, $matches);

foreach ($matches[1] as $match) {
    echo $match;
	// I want this to output "Zinfandel|Sauvignon Blanc" with a pipeline between the matches
}
?>

Any help pretty much appreaciated!

I'm using PHP to get a list of names from a mysql database, which then produces a drop down list for the user to select an option and then progress to the next page where the selection is displayed with other stuff. My problem is that my drop down list works fine, but when the user goes to the next page only the first part of the string is displayed, ie if the string is Fred Bloggs, only Fred is shown. I can get it to work by adding ' ' around the string name in the option section, but this shows 'Fred Bloggs' in the drop down list which isn't very pretty.

I haven't got the actual code to hand at the moment, but any ideas on where I'm going wrong?

Cheers

hi php freaks,

have link in a menu that looks like the following. I have been able search the string using
strpos($lines[$i],'title='). What I want to know is how do I get the  school summary into
a variable.

Code: [Select]
<li><a href="../index.php" title="school  summary">Summary</a></li>

any help would be great

Let's say I have a variable called $big_paragraph

I want to display the variable IF it contains the word "hello".  The word may or may not be there AND it could be anywhere in that paragraph (separated by a space before and after it to signify that it is a word).  So I can't use substr since it assumes I know the position.

Thanks.

Hello guys,

I want to remove part of a string and convert it to a var instead of echoing it out.. How would I do it..

$string = "temp_photo/testing.jpg";

I want to remove temp_photo

so the out put should be
$filename2 = testing.jpg

Please advise..

Thanks, Dan

Hi - newbie to php - I need to search a string and possibly replace part of it.  This is how I would do it in perl:

Code: [Select]
if ($homepage) {
if ($homepage !~ /http/i) {
$homepage = "http:\/\/" . $homepage;
}
}

I have a homepage field in the database but sometimes people put the http in, and sometimes they leave it out.  In perl I can figure it out and format accordingly but it doesn't work in PHP.  I'm not sure if the first line even works in PHP.  Maybe if to say something like:

if $homepage is not equal to nothing. I'm not sure.

Any help would be appreciated.

Thanks.

Hey guys I'm having an issue trying to get my PHP to display the first url of my exploded string and non of the others. The SQL table column contains strings like this:

http://www.imgurl.com/image.jpg,http://www.imgurl.com/image2.jpg,http://www.imgurl.com/image3.jpg,http://www.imgurl.com/image4.jpg

Hey guys! I found a flush function and it seems to be working well, but sometimes it will cut off characters. It's very strange.

Here's my flush function: function out($str) {
echo $str."<br />\n";
vbflush();
}

function vbflush() {
if (ob_get_length()){           
@ob_flush();
@flush();
@ob_end_flush();
}   
@ob_start();
}And I'm calling it like this:out('Waiting 30 seconds until execution');And this is my output: Code: [Select]
Waiting 30 seconds until executioAnyone know why?

I have the following DOM document ( this is a sample document and is "as is", it's 100% intended to look like this ):

<everything>
 <cars>
     <car>ladia</car>
     <car>ferrari</car>
     <garage>big blue building</garage>
      i also have a McLaren F1 but i wont brag about it
 </cars>
 <houses>
   <house>Big Red House</house>
 </houses>
</everything>

This is all being put into a
$newdoc = new DOMDocument();

$myString = ................. ; // ????? I only want the content of <cars> in here, and without having the <cars> tag


How can I make this "$myString look like the following:

$myString = '
     <car>ladia</car>
     <car>ferrari</car>
     <garage>big blue building</garage>
      i also have a McLaren F1 but i wont brag about it
';



Preferably without any looping.

Hey there.
Thinking this should be an easy one but I can only seem to find info on the string replace function.
What I'm trying to do is strip everything after the @ from an email variable.

So for example $mail variable comes in as
me@gmail.com

How would I strip the variable to only contain me and remove the @gmail.com

I'll keep searching for the answer myself but if anyone can throw me a bone it's be appreciated.

Cheers

Hi all, first time here as I am a bit stuck. I am by no means a programmer and I was hoping that someone out there may have a simple solution to my problem?... So here goes"

I have a voucher/offers site up-and-running. The site content is generated from an external feed. I want to create other sites and I want to track what sales/clicks have come from where.

An example of the feed: (http://www.awin1.com/awclick.php?mid=251&id=28971&clickref=[URL_REFERENCE]&p=http://www.247electrical.co.uk)

As you will see, I have [URL_REFERENCE] in each link. I want to automatically change that part of the string in the database. Does anyone have any thoughts?

Hello,

I have several job categories on a recruitment website:

$job_category[0]="accountant";
$job_category[1]="php programming";
$job_category[2]="baseball";

these job categories are contained within the urls imediately after the recruiting company's name and before the word "jobs", so we could have the following urls:

www.url.com/company_name_accountant_jobs
www.url.com/another_company_name_baseball_jobs
www.url.com/yet_another_company_name_php programming_jobs

Using the array $job_categories and the page path after the foward slash (e.g. yet_another_company_name_php programming_jobs) please could you tell me how to strip out the job category and the company name? (I'll extract the page path using a mod_rewrite)

Thanks
