PHP - Replace Part Of String

Hi i need help with some string manipulation and extraction..
http://www.test.com/forums/attachment/f39/745d1267084199-official-ar-m16-m4-picture-thread-dsc00005.jpg

I need to extract an id from the above path dynamically.
I need to extract the digits before the alphabet d after the second last  path f39/
In the above case the number extracted would be 745.
Can someone please help me out with it?

I have  string like this (without the spaces)

[ QUOTE="Adrock"]This is a test message[/QUOTE ]

How do i get just what is between the double quotes taking into account in the message there could be double quotes?

I've tried this but it doesn't echo anything unless i put the square brackets in but i want the username

$origauth = html_entity_decode($message);

$b = substr($origauth, strpos($origauth, '&#034') + 1); 

$c = substr($b, 0, strpos($b, '&#034')); 

echo $c;

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?

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

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

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.

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

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?

How can I replace the comma from a string like this:

You, like this => You like this
You, Derp, like this => You and Derp like this
You, Derp, Derpina, like this => You, Derp and Derpina like this
You, Derp, Derpina, Derpson, like this => You, Derp, Derpina and Derpison like this

Hi Guys

I'm sure this is really simple for you experts but it's proving to be my nemesis! I have an array of words: eg.

$words = array('Apples','Bananas','Cherries');

and would like to search a string of text for these words and create link tags around them based on a simple template, <a href="#">$word_found</a>

$text = "I love eating apples and bananas but hate cherries!";

So i would like to return a string like this:

$text = "I love eating <a href=#>apples</a> and <a href="#">bananas</a> but hate <a href="#">cherries!</a>";

Now, I need it to do a case insensitive search, but just wrap tags around the words it finds, leaving the case as it was found in the string. I want to avoid using a function where I have to list all the replacements like this:

function replace_text($text){
    $replace = array('apples' => '<a href="#">apples</a>','bananas' => '<a href="#">bananas</a>');
    $text = str_ireplace(array_keys($replace), $replace, $text);
    return $text;
}

because it seems very messy and long winded. Also it's not case insensitive.

It seems like there must be a way of simply searching for the words in my array and wrapping tags around the found words.

Please can anyone help!?

Many Thanks
Dan

Hi,


I am trying to take a string from a database and replace everything within {} with code... similar to how posting in a forum works.


so say I have "...Lorem ipsom {gallery:1} sit imet..."
it will take that string (from a DB) and replace "{gallery:1}" with "<?php gallery('1'); ?>". How can this be done? Or is there keywords I can search on to find the answer? Thank you in advance.

Hello All,
 
I've been knocking my head against the wall for several hours trying to figure out what's going on with a simple string replace.  For the most part it is working beautifully, but if a string contains a similar but not exact match it still replaces the non match.  I was under the impression that str_replace always looks for an exact match.
 
I have custom tags that are in strings of text that are structured like:  [A_CUSTOM_HEADER] [A_CUSTOM_TITLE]  and so on.  They always start with  "[A_CUSTOM"  and end with a " ] ".  In between the start and end can be just about anything.  So my problem is if I have [A_CUSTOM]  and [A_CUSTOM_TAG] in the same text str_replace seems to incorrectly replace all the [A_CUSTOM_TAG] with the [A_CUSTOM] content and the match never happens for the [A_CUSTOM_TAG] content.
 
For example:

$content = 'Here is some text and [A_CUSTOM].  Here is more text and [A_CUSTOM_TAG]'.
$content = str_replace('[A_CUSTOM]','I have a and custom',$content);
$content = str_replace('[A_CUSTOM_TAG]','I have a, custom and tag',$content);

So running that code The [A_CUSTOM_TAG] content never gets replaced correctly, it is replaced on the first pass with the [A_CUSTOM] replacement content.  
 
I hope this make sense I'm trying to explain it the best I can.
 
I tried using preg_replace() with \b to match the whole word but didn't get anything close to the respected results...haha
 
I'm sure I'm missing something simple...or at least I hope I am.
 
Thanks in advance!

May I please ask one more question? About replacing a string only if it appears *after* a particular string?   I'm having trouble replacing all occurrences of "wheel" with "TIRE" but only when the word "wheel" is after this:  (W/   Example:   From this: A large wheel is shiny. Big 4 wheel truck (W/ wheel) Car with a wheel, and a small toy (w/  wheel) Four wheelers are cool   To this: A large wheel is shiny. Big 4 wheel truck (W/ TIRE) Car with a wheel, and a small toy (w/  TIRE) Four wheelers are cool     Unfortunately, I thought this worked: $fixed = str_ireplace('wheel','tire',substr($original_string,stripos($original_string,'(W')));   ...until I realized it was *cutting off* all characters up until that first '(W/'   What can be done to make this work?
