PHP - Php5 Oop Crash Course!

Here is one of those purely conceptual questions, which involves no code.  I'm trying to create a select query which among other things, allows a user of a website to search other members who fall within a particular age range.  I have a column in the table where the members' information are stored which records their ages.  Which brings us to the problem.  On any given day, a member's age may increase by one year compared to what it was the previous day, hence the need to update this column periodically.  I can't think of any way to automatically update this column on a daily basis.  So my solution is to run an initial update query every time a member tries to search other members based on age, which updates the age column for all other members, before running the select query which eventually retrieves the desired age range.  This leads to the second problem.  Imagine there are thousands of users using the website.  At any given instance, there could be hundreds of members, trying to search others based on age.  This means hundreds of users will be updating a single column (the age column) in one table at the same time.  Is this feasible? Can it cause the server to crash? Or is there really a more reasonable way to do all of this? Thank you all for taking your time to read this. Appreciate any responses.

Helo,
I need big help how to adjust this code to new PHP 5.3 that dont support egeri any more

   public static function blacklist(&$query)
   {
      return eregi(self::$_blacklist, $query) ? true : false;
   }

HELP ! ! !

I need to produce 4 byte CRC32 checksums for UDP packets sent to an rcon tool for an online game.
The (brief) specification for formatting these UDP packets is he
http://www.battleye.com/downloads/BERConProtocol.txt
I have been converting the results of the CRC32() to hex and inserting it successfully in the correct part of the packet. The checksum result however is different from one that I packet captured from a working rcon tool. I have tried various methods of converting the int that CRC32 produces but have been unsuccessful in producing the correct checksum.

For reference below is the captured correct packet from the working tool. All data is the same as the packets my tool produces except for the checksum. The checksum is bytes 3,4,5 & 6. and is formed (to my understanding) by performing a CRC32 check on the subsequent bytes.

(From Smartsniff)
00000000  42 45 D5 C3 FB ED FF 00  61 62 63 64 65 31 32      BE...... abcde12

 If anyone has a working CRC32 class that could reproduce the successful hash above or has any pointers in the correct direction I would be very thankful.

I am setting up php5 on ubuntu 10.10
I can visit pages but they come up with errors

Code: [Select]
Notice: Undefined index: id in /var/www/alphawebpro.com/htdocs/index.php on line 5 Notice: Undefined index: action in /var/www/alphawebpro.com/htdocs/index.php on line 9 Warning: include(/var/www/alphawebpro.com/htdocs/home.php): failed to open stream: Permission denied in /var/www/alphawebpro.com/htdocs/index.php on line 105 Warning: include(): Failed opening 'home.php' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/alphawebpro.com/htdocs/index.php on line 105

Any idea as to how I fix this?

I have not been here for a long time, but just recently my php5.ini and .htaccess file got deleted while trying to install a new script. I have shared linux hosting at godaddy, but I cannot seem to get the code required inside these two files that would be standard or basic.   Does anyone have a sample code I can use on these two files?   Thanks in advance!

I'm sure this issue has been addressed before, but as I can't find anything on google OR bing, I've resorted to asking it he

Since, ereg and eregi are deprecated in PHP5, how do you test strings using regular expressions? Is there a new function for this?

EDIT: I also looked on php.net, but all it says is its deprecated in PHP5. I didn't see any links to the new function(s) that have replaced the former.

I just finished (or so I thought) a project. But my client's server runs PHP4, so I need to adapt my code. Here's what stopped working:

Code: [Select]
$localClasses = new DOMDocument;
$localClasses -> load("file.xml");
$localClasses -> get_elements_by_tagname('Title') -> item(0) -> firstChild -> nodeValue

Here's my petty attempt at trying to adapt this code to run in PHP4:

Code: [Select]

$file = file_get_contents("localClasses.xml");
$localClasses = new DOMDocument($file);

$test = $localClasses -> get_elements_by_tagname('Title');
$testText = $test -> item[0] -> firstChild -> nodeValue;
print $testText;


This doesn't give me any errors, but nothing shows up. Any help would be appreciated. Thanks for reading!

I had a website running a XML script which worked perfectly but I have updated it by using XMLReader and PHP 5. However, there is a security update on PHP 5 which prevents me from accessing files on my server.

Someone has suggested I add a php.ini file with the following:

allow_url_fopen = on

allow_url_include = on

However I have also read that the whole purpose of the security update is to prevent this. Can someone advise me how I can get around this issue so that my server can read files and still operate by the PHP5 security update.

Any help would be greatly appreciated.

I'm working on a website (for free) and the website owner has shared hosting w/ cPanel. When logged in to cPanel, the PHP version can be set to PHP5.5. So I did that. When logged in via SSH, scripts are still running on PHP5.3.   I found that /opt/alt/php55/usr/bin/php is a location of php5.5, but when I run my script, it gives an error that mysqli is not found.   As far as I know, this is probably just a typical cPanel install. If anyone can point me to the right way to run PHP5.5 from the command line, I'd appreciate it.

Been using these includes in php4 for a long time, but they don't work in php5.  Page loads, but included code is blank.

Code: [Select]
<?php include("http://www.xxxxxxxx.org/header.php"); ?>

 

I am trying to convert a php4 app to php5 and am getting this error (Fatal error: Cannot re-assign $this in ) when I call this class.

$this = $this->createUnique($new); is the line that generates the error.

I try to rename $this to $_this but it does not help. I think I lose the reference to the object later on in the code.

Then I will get an error like (Fatal error: Call to a member function createUnique() on a non-object in)

Is there another way to reference the current instance of an object in php5?

Any help appreciated...



Code Example:
Code: [Select]
class imageobject{

var $handle;
var $height=0;
var $width=0;
var $directory;
var $filename;


//constructor
function imageobject($directory,$filename,$width=0,$height=0,$color="FFFFFF")
{
$this->directory = $directory;
$this->filename = $filename;

if ($filename=="" && $width>0 && $height>0){

$new = $this->createImage($width,$height);
$this = $this->createUnique($new);

}elseif (file_exists($directory.$filename)){
$size = GetImageSize($directory.$filename);
if ($size) $this->handle = $this->getHandle($directory.$filename,$size[2]);
$this->width = $size[0];
$this->height = $size[1];

}


function createUnique($imgnew)
{
$this->type = substr($this->output,0,3);

$unique_str = $this->uniqueName();
switch ($this->type){
case "png":
imagepng($imgnew,RES_DIR.$unique_str);
break;
default:
imagejpeg($imgnew,RES_DIR.$unique_str,$this->quality);
break;
}

$this->handle && imagedestroy($this->handle);
$newobject = new imageobject(RES_DIR,$unique_str,$this->type);
return $newobject;
}

)//end class

Hello everyone.
I have a problem with the local server (localhost connection). Until yesterday I used an old version of XAMPP's (version 1.6.4 with PHP 5.2.4) and last night I finally found the time to install XAMPP 1.7.3 with PHP 5.3.1. But some things that I worked under the old XAMPP-om, which are working perfectly now no longer work, and I do not know why. Please find enclosed pics that were under php4 and that now works. So I wonder where is the error and where possible errors. Also under my new PHP-om non-stop is done refresh the page and print portions of the code (as you can see from the picture).
I am enable short tags support in php.ini.
Thank you.
PHP 5.3.1

PHP 5.2.4

Most of my website is written in php4. My hosting server has support for both 4 and 5 just by changing file extension. .php which is the default supports 4, .php5 of course supports 5. The problem I am having is that the pages with the .php5 extensions are not recognizing session variables. Is there something I should be doing differently in 5 for my session variables?

For example a variable request like this returns 0

print $_SESSION['FULLNAME'];

Please Help!! Thank you in advance?
