[Wierd Opera thing]

Just out of curiosity, why are you concatenating this?

 

Why not just use:

 

echo "a<br />b<br /><br />c";

[php enabled videos]

Of course it can, directly from the PHP website.

 

PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML

[Sorting Algorithm]

Yes

 

$sql = mysql_query("SELECT * FROM table1 WHERE field1 LIKE '%". $string ."%' OR field2 LIKE '%". $string ."%'");

[Sorting Algorithm]

A) Why not separate the name into separate columns, and

B) You can always use mysql string functions in the query to extract the last name, but this or any use of php code to accomplish this will always be slower than using option A).

 

You've just got to remember, the over-all system will thereby be improved by doing so.

[sessions being emo ...]

That's because it should be

if (!isset($_SESSION['id'])) { ... }

You want to check if the user hasn't logged in (i.e. the ID session variable hasn't been set) then re-direct to index.php otherwise display the page.

 

You've got it the opposite at the moment.

[Randomly displaying a list of links]

No they will be in the php code and not from a database, thank you to all who have replied so far

 

Well in that case, the code I posted before will work if the links are in an associative array. I've tried and tested it and it works fine as far as I'm aware.

[force json_encode not to put quotes]

json_encode simply sees '$(this).val()' as a string, which it is. If you want it evaluated by Javascript you will need to execute it via js's eval method.

 

I.e.

 

eval(json.data);

[sessions being emo ...]

The code:

<?php
if(isset($S_SESSION["id"])) {
session_start();
connectdb();
$username = $_SESSION["username"];
$query = mysql_query("SELECT * FROM ov_users WHERE email = '".$username."'");
$rows = mysql_num_rows($query);
if($rows = 0 || session_id() != $_session["id"]) {
session_destroy();
header("location:index.php");
}
				}

 

The first line

$S_SESSION["id"]

 

should be

 

$_SESSION["id"]

 

Simple typo...

[Randomly displaying a list of links]

i know a small code it is not of ur requirement but i think this would give u an idea

 

<? 

//set the urls 
$urls = array("http://google.com" ,"http://hotmail.com" ,"http://phpfreecode.com" ); 

//set the text links 
$text = array("Google" ,"Hotmail" ,"phpfreecode"); 
        srand(time()); 

//set the number in (rand()%3); for however many links there are 
        $random = (rand()%3); 
echo ("<a href = \"$urls[$random]\">$text[$random]</a>")."<br>"; 


?>

 

I don't see how that will echo all of the links?

 

Straight from PHP.net for associative arrays, keeping the key => value pairs in tact.

 

<?php
function shuffle_assoc($array) {
  $keys = array_keys($array);
  
  // Shuffle the keys
  shuffle($keys);
  
  // Re-assign each new ordered key and value pair to a new array
  foreach($keys as $key) {
    $new[$key] = $array[$key];
  }
  
  // Return the new array
  return $new;
}

// Array of websites, the URL is the key and the label is the value
$sites = array('http://www.google.com/' => 'Google', 'http://www.phpfreaks.com/' => 'PHP Freaks');

// Loop through each element in the newly ordered array
foreach (shuffle_assoc($sites) as $key => $val) {
  echo '<a href="'. $key .'">'. $val .'</a><br />';
}
?>

 

If you're getting these values from a database then it's best you use the RAND() MySQL function.

[cant find the error in my code.]

Does it not spit an error back out at you?

[grouping with arrays]

The quickest and easiest way I can see is

<?php
$array['a'][0] = 3;
$array['a'][1] = 1;
$array['b'][0] = 2;
$array['b'][1] = 1;
$array['c'][0] = 0;
$array['c'][1] = 1;

foreach (array_keys($array) as $key) {
  $array[$key] = array_sum($array[$key]);
}

print_r($array);
?>

Array ( 
  [a] => 4 
  [b] => 3 
  [c] => 1 
)

[trim all of strong after #]

I think the shortest and easiest way to do this would be to strip white spaces from the string completely, if that's what you're trying to achieve.

 

<?php
$str = "hello# myname is#meh";
$str = str_replace(" ", "", $str);
?>

 

[trim all of strong after #]

Why not just use str_replace to replace all white spaces? (if that's what you're after)

[multiple mailing like 10,000 mails]

Nobody will write the code for you, check out the freelance forum if that's what you're after.

 

However, I will provide some resources for you to help you create your own mailing script.

Google is your friend, the Internet is a wonderful thing.

[Why not vBulletin?]

I agree, keeping PHPFreaks the way that it is has proved successful thus far. Don't try and fix something that doesn't need fixing, that's where Facebook is beginning to go wrong.

 

Although, I've been playing about with "MyBB". Which is another open-source and free forum solution, it's pretty nice.

[MSSQL Views and PHP]

I've just been assigned an urgent project at work regarding MSSQL Views.

 

However, our Intranet runs Drupal (which is written in PHP) so I was wondering if I just treat MSSQL Views the same as I would an ordinary MySQL table?

 

Thanks

A little respect and common sense goes a VERY long way.

We can only do so much in so little time.

[Seesions or cookies?]

All cookies are domain specific. There is no such thing as an "open" cookie that is sent by the browser to all domains.

 

So then how does Facebook store cookies that enables other websites to identify your Facebook identity?

[Seesions or cookies?]

Other websites could quite possibly access your cookies (which is bad if they contain user sensitive information).

 

Facebook, for example have a few 'open' cookies where they're accessed by many websites you may visit.

[[SOLVED] Pushing a variable through while using header()]

Probably GET would be the best method.

 

header('Location: search.php?find=' . $find);

 

Then you could recover it in search.php using:

 

$_GET['find']

[[SOLVED] url rewriting (noobish)]

You should use mod_rewrite in a .htaccess file on your server.

[Hanging AJAX]

The rest of the script wouldn't necessarily need to be executed. You're only needed to listen for any new messages that have been sent and retrieve them.
