PHP - Finding The Difference Between Two Variables

Okay I'm done with searching for answers, working on this preg_match for about 3 hours now.   I'm looking for "($0.01/$0.02 USD)" in a string. The needle might be slighty different. Possible strings that I might look for is:

(€xx.xx/€xx.xx EUR) where the EUR can be changed into USD, including its signs.

Hi

I have a file, that is copied from other files. All other files work perfectly.
But, for some reason this one is throwing back an error.

I've been over it so many time, but can't see whats wrong.

Error:

Any help finding this bug will be a big help.

Thanks

My query is not finding the last recieptnum entry, it is finding the number 9 everytime for some odd reason. Im trying to incrementally increase this each time a reciept is created.

$getreceiptnum = mysql_query("SELECT receiptnum FROM accounting WHERE agency = '$agency' ORDER BY receiptnum DESC LIMIT 1") or die(mysql_error());
        $recieptarray = mysql_fetch_array($getreceiptnum);
        $recieptnum = $recieptarray['receiptnum'];
        echo $recieptnum;

Hi ,

I'm new on this forum so don't judge too hard.. But I have a few questions. I am recently new to PHP as this is my first computer language I've learnt besides HTML.

My first question is, what's the difference between !== and !=, and is it more secure to use !== when comparing two fields such as passwords? I've different things and this has confused me.. 

And my second question is, I have this piece of code

Code: [Select]
/* option error checking */
      $field = "option";  // Use field name for option
         /* Check if the option picked is from the list of options to choose from*/
      if($suboption !== "option1" || $suboption !== "option2" || $suboption !== "option3" || $suboption !== "option4" || $suboption !== "option5" || $suboption !== "option6" || $suboption !== "option7"){
            $form->setError($field, "* Unexpected error with option");
      }
I'm guessing in the long run, this will slow down my script.. is there an easier way of checking without using || $suboption !== and is it okay if I've used !==?
Like I said I'm new to this so please don't flame.. I've done some research but I can't seem to find some accurate answer.

Thank you,

ZT

User submits 1 or more refrerences via a form.  On the action page I want to check if any id's on the page match any values submitted in $_POST.
Code: [Select]
$Ref = $_POST['Ref'];
$source = file_get_contents( 'E:/wamp/www/Project/File.php' );
$document = new DOMDocument;
$document->validateOnParse = true;
$document->LoadHTML($source);
for($i=0; $i<count($Ref); $i++)
{
$ID = $document->getElementById('$Ref[$i]');
}
I have a table on the source page with the same id as a reference contained in $Ref, but getElementById is not seeing/recognsing it.   No idea why not.

Howdy Colleagues,   I was wondering whether you know ways/websites/channels/magic owls to how to help find a job in USA as a programmer as in for relocating there while the company pays for the Visa and the travel expenses?   My land-lord's son found a job as a programmer in Texas and the company was generous and kind enough to pay his travelling expenses, as well for his wife and kid.    I have an account in Monster & Indeed and I send CVs very often, but no luck so far.   And I want to go there to work and live, not like some people to rely on welfare, I have worked my whole life.    Thank you!   BR, Stefany

What I want to be able to do is this:

If I have a list of values in my database:

1
13
26
15
12
4

I do a query of this database and sort it asc so it looks like this:

1
4
12
13
15
26

I want to know how I can use php and/or sql query to find these values based off of "position" in the list.

If I wanted the 3rd value in the list, that value would be 12.  If i wanted the 2nd value in the list it would be 4.  How would I go about doing this?

Thank you in advance.

Hello. I think I have a little unique and difficult to solve problem that I really need to post here.

I, as a counter-strike portal administrator, am running some CS servers. With automatical script, the server uploads demos (videos of gameplay) on FTP in this format: 101229154428.dem and so on. The number is a date in this format: year, month, day, hours, minutes, seconds => for the example it's 29th December 2010, 15h, 44m and 28s.

Then I have a "report" page. The important part on it is that, there is a date in unix timestamp in each row like 1336837680 (29th december 2010, 15h, 47m, 00s). And now what I need:

Find a demo that corresponds to the unix timestamp. If there is a timestamp 1336837680, it should find 101229154428.dem.


You know what I mean, there is not one demofile, there are plenty. Just find the demo, that contains a record of the time used in timestamp.

Pretty difficult, isn't it? I would love to see if anybody came up with anything.

Best regards!

I am trying to find the URL to a directory TWO levels above the script level (if you know what I mean).

For example.. the script sits at
Code: [Select]
http://www.domain.com/TestArea2/members/index.php
BUT I need to find the path to 
Code: [Select]
http://www.domain.com/TestArea2/

the nearest I get is...


$domain = $_SERVER['HTTP_HOST'];
$domain .=  $_SERVER['REQUEST_URI'];
echo $domain; // outputs www.domain.com/TestArea2/members/index.php 



Is there a simple method to do this or have I got to split the string and work backwards?

Many thanks

Im trying to find the time between the last database entry and the current time and then echo it so it says something like '2 minutes ago'. I tried doing:

$last_post_gap = strtotime('NOW') - strtotime($topic_info->topic_last_post_time);
$last_post_gap = date('i', strtotime($last_post_gap));
$last_post = date('F j, Y', strtotime($topic_info->topic_last_post_time));


if ($last_post <= '- 1 DAY') 
{ 
$last_post = 'Yesterday at '.date("g:i a", strtotime($topic_info->topic_last_post_time)); 
}
if ($last_post <= '- 1 MINUTE') 
{ 
$last_post = 'Less Than 1 Minute Ago'; 
}
else
{
$last_post = $last_post_gap.' Minutes Ago';
}

but that just displays 0 minutes ago regardless of the time.

Is there anything im missing?

//calculate age
$birthdate = "1978-04-26"; //birth date... actually being obtained from a database
$today = date("Y-m-d H:i:s"); // The exact date
$age = date_diff($str_birthday, $today);

echo $age;


I'd like a simple code to echo the age of someone with the mysql database information that's in their record. This doesn't work. I have no idea why. Nothing seems to work that I've found on the net. Please help. Thanks.

I am working with wordpress and I see a lot of "if" statements done like this

if(condition):
    do something
endif;


I have always done it like so

if(condition) {
  do something

}

what is the difference? does the first method have any advantages over the second method?

Actually what's the difference between
Code: [Select]
if(...)
and
Code: [Select]
if(isset(...)
