PHP - Conditional Execution Of Codes

Hello,

I have the following code:

<form method="post" action="<?php echo $_SERVER['REQUEST_URI']; ?>" name="loginform" id="loginform" class="niceform" ">

The problem is that the code isn't executed after the action="<?php echo $_SERVER['REQUEST_URI']; ?>" so the result doesn't have css.

Any ideas?

Folks,

I am running Linux Commands in PHP.

I am looping through the Domain list and using the below line in my Script:



exec('cp -r '.$source.' '.$destination);



I am using this in a Foreach Statment, so only the last Even in the loop getting executed, because, the loop is running too fast so the Linux command does not even get initiated, only the last even in loop goes through.

What i have done is, i have added a line after exec();

sleep(30);

This gives enough time for Linux command to get executed, but is it efficient way to handle timing liek this?

Do i need to use time_limit() or something like that?

Cheers
Natasha

Hi All,   I'm hoping somebody would be able to help me with a performance issue I'm having with a bit of code I've written.   The setup:   Client request arrives on Apache2 reverse proxy over HTTPS. SSL is offloaded and proxy initiates connection to backend development web server over standard HTTP. The website is being developed using HTML5 syled with CSS, Javascript (to dynamically show counters on message text area, perform client side validation for browsers that do not support the build in HTML5 input validation) and PHP for server side validation and form submission (sends email to webadmin).   The development web server is located in a LXC container on the production web server. The host server presents the "public" IP address to the physical network and uses UFW to NAT all traffic inbound and outbound from the development website to trick the network into thinking that the server is on the physical network (Only way to get it routeable across the rest of the network).   The problem: On form submission, if I intentionally leave the fields blank and turn off client side validation, the script echos "An error occured in your form, please check to make sure that all relevent fields are filled in!!!". This response returns in 16.50ms with a latency of 34.92ms. The POST appears instantly in the Apache2 logs less than a second after I submit the form.   If I submit the form with all fields (Name, Email, Phone, Website, Subject and Message), it takes 60 - 65 seconds before Apache logs the POST has arrived. I'm not entirely sure why its taking this long for the server to receive the content. GET Requests are pretty much instant as I would expect. Could this be an issue with inefficient scripting that maye be causing this type of delay? This issue occurs regardless of whether I use firefox or Safari.   Could this be a result of inefficient scripting? Using timelines in Safari and on form submission with content, I get 1.0min latency with an actual duration/script run time of 5.336ms. Where would this latency be coming from? Standard GET requests for HTML and CSS content is instant, next to no latency but once the Payload increases in size, it seems like I run into the issue.   Any views, thoughts or possible things to try would be hugely appreciated. I'm learning the ropes with scriping at the moment but this high latency, as a hunch, appears to be server related. Happy to upload the submit.php script and web form if it will help.   Many Thanks, A  

I have this one issue.  While logging in into our system, we call a routine called getToken().  This calls a routine on another server (used to be able to securely access documents).  The issue we have is if that other server goes down, this call fails, and the user isn't able to login.  I want to make it so that even if the other server goes down, users can still login and access our system (just not documents). 

I know that I can't prevent fatal errors or even ignore them, correct (even with set_error_handler)?

Any thoughts?  It's a simple call, here's all it is:


require_once('include/utils.php');
$token=getToken();

Hello, i've been coding a CLI php mailer which i'm using with a webshell.

My problem shows up when i execute my mailer, the hole server crash or in the best case scenario it slows down a lot.

In the same folder that my script was executing a huge error log appears with this error repeated:

I'm not getting why this happens since i just use normal functions like mail(), fread(), etc. I'm not using any sql function or anything like that.

Any clues?

Another non related thing i wanted to ask was: Is it possible to make an "interactive" cli script? I mean using a similar function like getc() in C or something.

Guys, why the following mysql stored procedure taking much more time comparing with firebird one?   1. MySQL stored procedure

CREATE DEFINER=`lxc`@`::1` PROCEDURE `insertData`(IN it INT)
BEGIN
      declare i int Default 0;
      declare str char(4);
      declare p_hash int;
      myloop: loop
      set p_hash = round(rand() * 999);
      set str='book';
      insert into test.users (name,password) VALUES (concat(str,'_',i+1),PASSWORD(p_hash));
      set i = i+1;
      if (i = it) then
        leave myloop;
	end if;
    end loop myloop;
  end

Object info:

Table: users
Columns:
id	int(10) UN PK AI
name	varchar(45) 
password	char(41) 

Time:

mysql> call insertData(10000);
Query OK, 1 row affected (9 min 38.22 sec)

2. Firebird Stored Procedure

SET TERM ^ ;
CREATE PROCEDURE INSERDATA (
    IT integer ) --iteration number

DECLARE VARIABLE i integer; 
BEGIN
i = 0;
while ( i < it ) do
begin
INSERT INTO PRODUCT( CODE,NAME,PASS) VALUES(:i, 'jazz_' || :i, fb_hash(round(rand() * 999)));
i = i + 1;
end
END^
SET TERM ; ^
COMMIT;

Object Info:

Table: product
columns
CODE integer,
NAME varchar(45),
PASS CHAR(41)

Time:  ( for 10 000 records it takes less than 1 sec for execution)

Do you see something wrong in mysql stored procedure code?   jazz.

Hello all, newbie here just trying to understand PHP and other languages. As a basic, i understood that exit() function is used to stop something. But, was wondering if below code is right to terminate something. Ref - InterviewBit

<?php
$site = "https://abcdefghijk.com//";
fopen($site,"r")
or exit("Unable to connect to $site");
?>

TIA!!

Warning: mysql_query() [function.mysql-query]: Access denied for user 'ODBC'@'localhost' (using password: NO) in C:\xampp\htdocs\page\verify_security.php on line 170     earlier the code has been running fine and now it is showing error to me , can you tell something more about it ???

Hey guys, I was wondering if it is possible to have a value inserted into a table as someone clicks on a link (in order to count views for example)?

thanks!

I've been using php for a while now to create forms, up until now i've always transmitted the form data to a new php document that then processes them. I wanna take this to the next level and start trying to process the data within the same document. I know this has something to do with checking if the submit button is pressed and then processing the submitted data but thats about as far as my knowledge goes.

Can anyone help me out on  how i can achieve this type of thing. The reason is that i've found a way to execute php code within a joomla 1.6 environment without having to use the iframe option. I know the iframe option may be easier in a way of doing things but its out of the question. The final fase of the php will output code that will trigger a specific joomla plugin to do some specific action. If i pull a php document via an iframe the plugin doesnt trigger as it only gets triggered after the joomla "afterRender" (or something" has executed. If i use the iframe option then that rendering never gets used so the plugin doesnt get triggered.

So in a nutshell, i wanna create forms that submit data and that data gets processed in the same document (in this case joomla article). How do i go about doing this.

I have a simple script that imports all images in a folder to my site and generates thumbnails. It works, but on folders with a rather large amount of images (500+) it can reach the max execution time and give a fatal error.

I could always break up my import folders into smaller chunks or increase the max execution time, but I am wondering if there is a different approach I could take.

Is there a way to reset the execution time of a script by inserting some kind of a pause/delay?

I got 30 files to convert to png each in a dir containing 5 files
I get the maximum execution time when i run the following code:
Code: [Select]

$dir = glob("images/*/*.png");

foreach($dir as $file)
{
$filename  = $file;
$files = getimagesize($filename);
$img = imagecreatefrompng($filename);
imagepng($img,$filename);
}

I have a very weird problem on my PHP5.3/Apache/MySQL based system on WinXp Pro.

I have written php script which basically scans every directory in my local hard disc, checks which files are images, sets a counter of the number of images found per folder and saves this count in a MySQL table.  To put you in the picture, we are talking about 1000 folders with about 8-10pics each on average 9000 files.

On the previous PHP 5.1 / IIS system, (same PC) this used to work moderately well (took a nice 6 mins) and I had to include the command set_time_limit of about 3seconds in the looping to avoid execution timeout failures. (also worked by setting a high value of 10mins before the loopping)


ANyway, now I run the exact same script on the new Php5.3 and have the problem that the code starts operating quite fast and gradually it slows and slows until eventually it is dead slow and have to quit internet explorer. For exampe, the first 3000 files are scanned in just 60seconds, then the next 1000 in the next 4 mins, and eventually drops to about 100files or less files per minute. I also noticed that the CPU consumption of iexplorer.exe is 90-99%, and the window of Internet explorer is very slugish with a temp '(not responding)' messages on the top window bar.

WHat can I do and test? Is it the code itself, the PHP5.3 or something in php.ini or apache conf. file? Buffers? memory? WHat? gonna crazy!


basically, the code scans a dir (location of dir taken from Mysql) puts file contents in an array, analyse the array for .jpg/.gif (and other parameters specific to pics, counts the valid pic files in a variable, puts  this in a MySql databse, loops for next folder.

The code is a kind of tool to have a count of my pics in my folders and never used remote server/online but only local.

Thanks for your time
