PHP - Percentage Difference Between Strings

This topic has been moved quickly to PHP Regex because I need to go to work instead of lurking phpfreaks.

so pls guys if you have these codes, pls share it .

I'm making a login area for the hotels in a booking system, where they enter their hotels' information, policy, and room rates
but I want to make the room rates when it appears for clients, it appears with a percentage (commission) added to what the Hotel representative will enter

So what's better? it should be added in the admin area of the hotels and gets saved in the database with the commission or I should add it in the booking form so the code grab the rate from the database, multiply it by the percentage and echo the result?

Hi all,   I am building a random prize assigner function based on weighted percentages.   I am able to assign a basic true/false weighting but am struggling to form a way of selecting an array based prize based on the win rate.    Heres my current code:

function selectPrize() { 
    
    $prizes = array(
        0 => array(
            'name' => 'Top Prize',
            'rate' => 50
        ),
        1 => array(
            'name' => 'Middle Prize',
            'rate' => 30
        ),
        2 => array(
            'name' => 'Bottom Prize',
            'rate' => 20
        ),
     
    );
    
    // oops
} 

selectPrize(); 

Could somebody please give me pointers on how i could approach this?   Thanks.

Hello,

I was wondering if someone could help me to "get" the webaddress of a current webpage and then pull off pieces of the page.  All of my pages look like:

http://localhost:8888/algebra_book/Chapters/Quadratic_Functions/introductory_problem.php

BUT, the stuff to the left of Quadratic Functions WILL change in the future.  So all will look like:

*Quadratic_Functions/introductory_problem.php

Then, I'd like to pull off a $chapter variable, which in this case is Quadratic_Functions and a $page_name variable which in this case will be introductory_problem.

Thanks so much.

Hi

I am having troubles using a string in a cookie..

This doesnt work:

setcookie("background", "$image_name", $expire, "/", ".gedoo.com");

Neither does this:

setcookie("background", "" . $image_name . "", $expire, "/", ".gedoo.com");

If I write something before $image_name like:

setcookie("background", "hello" . $image_name . "", $expire, "/", ".gedoo.com");

It will save "hello" in the cookie.. So in other words, $image_name doesnt look like it is defined.. But the funny thing is that this works on the same page:

echo "File Uploaded Successfully!<br><img src='images/$image_name'>";

Anyone have any idea on what I am doing wrong?

Hey guys!! So basically what I am doing here is pulling the directory out of a url.

URL ex: http://www.xxx.com/T...IS_WHAT_I_WANT/

is there a way I can make something like a ticket in pdf format that can have $name or the likes echo in it?  if you could help get me started, that would be great!

I was thinking how can I make a script that will build strings incrementing through each letter starting with "a" and ending with "zzzzzz" or what ever ending length I want such as 12.

So if your were to output everything, you could find the words:
"dog"
"spider"
"superman"
"hippo"
etc

What would be the best way to do this, so I don't have to have a loop that is 500 blocks deep to show a word that is 500 letters

example
Quote

a
...
z
aa
ab
ac
...
az
ba
bb
bc
...
...
aaa
aab
aac

How can i break down strings for example i have a simple search database for products where as a user searches a term this can be one, two three words and so on.

I'm using a wildcard; but i want the best way to get the possible search so i would like to break down the string into separate words and then use that to search the database using wildcards

is this possible?

Thanks for reading. 

Not sure if there is a better way to do this, but I want to check whether the value in a Sticky Field is the same as what is in the Database.

If what is in the Sticky Field is *exactly* what is in the Database, then the User didn't update that field, and so I would NOT do an UPDATE.

Seem reasonable?

Here is where I grab the value out of the Form...
Code: [Select]
// ****************************
// Process Each Form Field. *
// ****************************
foreach($_POST['answerArray'] as $questionID => $response){
// Copy trimmed Form array to PHP array.
$answerArray[$questionID] = trim($response);


And here is where I grab the existing value in the Database...
Code: [Select]
// ********************
// Check for Answer. *
// ********************

// Build query.
$q1 = "SELECT response
FROM bio_answer
WHERE member_id=? AND question_id=?";

// Prepare statement.
$stmt1 = mysqli_prepare($dbc, $q1);

// Bind variable to query.
mysqli_stmt_bind_param($stmt1, 'ii', $memberID, $questionID);

// Execute query.
mysqli_stmt_execute($stmt1);

// Store results.
mysqli_stmt_store_result($stmt1);

// Check # of Records Returned.
if (mysqli_stmt_num_rows($stmt1)==1){
// Answer Found.

// Bind result-set to variable.
mysqli_stmt_bind_result($stmt1, $currResponse);

// Fetch record.
mysqli_stmt_fetch($stmt1);


So I guess I want to compare $answerArray[$questionID] against $currResponse and see if there are any differences?!

What is the best way to do that?

Any better ideas of how to check to see if the User made any changes to a field so I only do an UPDATE if there was actually a change?

Thanks,


Debbie
