http://www.phpfreaks.com/forums/index.php?topic=322069.0 Similar Tutorialshi guys. i'm new to php and Apache and i have a problem. i'm trying to execute an exe file that i have in my folder, and the code i use is Code: [Select] echo exec('test.exe');i have tried using this with and without the ".exe." and still no luck. i have also tried using a different path Code: [Select] echo exec('C:\Windows\System32\mspaint');now these codes work when i run them from my php editor(PhpED), bun when i try running it on Apache it gets stuck. (just shows the web page as loading with no end. please help me out. i'm guessing it something with security. also if there is any other code i can use please let me know (i have also tried using system) I'm getting a '500 Internal Server' and 'Premature end of script headers..' errors in the process of uploading a file. This occurs consistently with files > 2MB but also (very occasionally) w/ smaller files. The target directories are beneath the web root folder, so I don't think it's a permissions issue. I've set the following in my php5.ini: post_max_size = 8M, upload_max_filesize = 8M max_input_time = 360 max_execution_time = 360 Trace code/logging reveals that the error occurs even before my upload code is entered (which uses (move_uploaded_file()). So what would cause that? Any suggestions on how to debug this are very much appreciated! I am just starting my first solo web project in a new language (php) and since I don't have my old boss to go to for code help I need to build a stronger set of debugging strategies or at least a set of debugging strategies that goes beyond echo $varthatmightbegivingmetrouble . Right now I'm working with this line of code right he $query = sprintf("INSERT INTO Users (UserName, Password) VALUES ('%s', '%s')", mysql_real_escape_string($UserName), mysql_real_escape_string($Password)); echo $query; which is outputting: "INSERT INTO Users (UserName, Password) VALUES ('', '')monkeykoder" Any help would be greatly appreciated. folks, i know i may be asking a question that has been answered before but i am asking this here again because i could not find any simple and straightforward answers. i want to debug my php scripts. no web server is involved. all the scripts are used for parsing and preparing data files...something like we do with unix shell scripting. the scripts reside on a linux box and each script may call functions in other included scripts. i can connect to the linux box using my notebook. on my notebook i have Eclipse and PhpEd. i want to debug those php scripts on the linux box using my notebook's Eclipse or PhpEd. (no webserver or html involved and php cli is already setup and running scripts on the linux box). If this (using PhpEd and Eclipse on the notebook to remotely debug) is not possible can you please suggest me how do i debug those scripts while i am on the linux server (using command line etc.). please help me how to set up. regards, kali I'm new to php and having some trouble with debugging a piece of code. Could someone please help me understand what's the error. I'm using Code Lobster for debugging and attempting to validate input for a simple sign in form. The error is and code is shown below. If I can understand this, I think I can continue with the rest of the checking. Parse error: syntax error, unexpected T_FOREACH, expecting ')' in C:\wamp\www\login_check_blank.php on line 20 <php // Program name - login_check_Blank.php // Description - checks form for blank fields // Date - 10/26/10 // Programer - R.

I spin up a VirtualBox and installed apache2 on ubuntu. I created the netbeans project from my linuxMint to the virtualbox apache2 server (remote server) and configured the virtual directories on the apache2 server. I can the test project successfully, however I cannot seem to debug via Netbeans like toggling a breakpoint to view variable values. I found on the internet i need to configure xdebug and followed this site and used this page https://xdebug.org/wizard.php to create and install my xdebug. I then updated my php.ini file to the following:
[xDebug]
While my netbeans session id is configured "netbeans-xdebug" and debugger port to 9000. However, when i set a breakpoint in my code, netbeans seems to be stuck on "Waiting for connection" even it already passed the breakpoint. I suspect it's not even connected at all. I do see from my host laptop (where I am running netbeans) that port 9000 does open when running the project with debug and ufw is turned off in both virtualbox machine and laptop.
Any ideas? I'm a beginner. I should debug my code from the webserver. When i use arrays and get some error, i generally make "var_dump" or "print_r" to check my data contents. Most of the time, by echo'ing, i can get the errors with related to structure of arrays etc. But when dumped file is too big, webserver crashes. I use shared hosting, so it becomes problem. For example Code: [Select] $html = file_get_html( 'http://www.example.com' ); var_dump($html);I suppose, PHP runs it very long and reserved memory, RAM etc. becomes exhausted. To solve this i sometime write the outputs to txt files. But it would be handy to check the results from browser. What can you recommend me to not to crash server?

I've tried to debug them various ways, but to no avail. This is the offending code: class DBOPS { protected $config, $mysqli; public function __construct () { $this->config = array (...snip...); $this->mysqli = new mysqli ($this->config['server'], $this->config['username'], $this->config['password'], $this->config['database']); session_start(); } public function Login ($username, $password) { $toreturn = NULL; //Problem area is from here... $encryptedpassword = hash(...snip...); print_r(array( $this->config['usertable']['username'], $username, $this->config['usertable']['password'], $encryptedpassword)); $statement = $this->mysqli->stmt_init(); $statement->prepare('SELECT * FROM users WHERE ? = ? AND ? = ?'); $statement->bind_param( 'ssss', $this->config['usertable']['username'], $username, $this->config['usertable']['password'], $encryptedpassword); $statement->execute(); print_r($statement->affected_rows); //To here. if ($statement->affected_rows == 1) { $_SESSION[$this->config['sessiondata']['username']] = $username; $_SESSION[$this->config['sessiondata']['lastactivity']] = time(); $toreturn = TRUE; } else { $toreturn = FALSE; } $statement->close(); return $toreturn; } The print_r($statement->affected_rows); statement always returns -1, which means a query error. Is there a problem with the syntax of the predefined query in $statement->prepare('SELECT * FROM users WHERE ? = ? AND ? = ?') ? I really can't seem to find the problem in this code. There are no errors returned. The output from the print_r() statements are Code: [Select] Array ( [0] => Name [1] => Trey [2] => Password [3] => ...snip... )from the first print_r and Code: [Select] -1from the second. And lastly, I know that DIY login systems are generally discouraged, but this is more of a research project. I would greatly appreciate any help with this. Thanks.
