PHP - Why Is This Regex Failing?

I'm compiling and running C++ applications from PHP. I'm using backticks to capture the output of the applications ran. The output is just some simple text. In my case "Miles per gallon = x" where x is just a number. I cannot for the life of me get the comparison to return true. For example

Code: [Select]
$command1="./a.out1 <input1";
$a = `$command1`;

$command2="./a.out2 <input2";
$b = `$command2`;

if(strcmp($a,$b)==0){
...
}
else{
// this is always executing
...
} 
The two strings $a and $b are both "Miles per gallon = 10".

I have checked both variables using var_dump(bin2hex($a)) and get
dump1= string(42) "4d696c6573207065722067616c6c6f6e203d203130"
dump2= string(42) "4d696c6573207065722067616c6c6f6e203d203130"

Any idea on what's happening?

OK, so I dont think this is a code issue as such, but I am completely stumped as to where the issue could be.

I have a page with some standard include() functions at the top. When I access the page from home, everything operates as it should, when I access it from work (on multiple machines), I get the standard "unable to open stream" and "unable to access" warnings for the include statements. I have tried hard refreshing and deleting cache (not that it should make a shred of difference) etc, but the error is still there after a week or so.

Does anyone know what could be causing this issue?

My application just broke about 2 hours ago and for the life of me I don't know what I did to it?!     (I was coding a different file, and when I tried to run the main - unrelated index.php - things stopped working?!)

Here is a snippet of the suspect code...

if ($rows == 0){
// Email and Username are available.
// Add User to the database.
$q = "INSERT INTO users(username, email, pass, first_name, last_name, date_expires)
VALUES('$u', '$e', '" . get_password_hash($p)
. "', '$fn', '$ln', ADDDATE(NOW()), INTERVAL 1 MONTH))";
$r = mysqli_query($dbc, $q);


When I step through my code in NetBeans, the INSERT is failing and I don't know why because I haven't touched this code since this morning and it was working all day...

Please help!

Another bizzare thing that stopped working all of a sudden...

I have a registration form and this code no longer works...

// Check for First Name.
// Allow letters, space, period, apostrophe, and hyphen.
if (preg_match('/^[A-Z\'.-]{2-20}$/i', $_POST['first_name'])){
$fn = mysqli_real_escape_string($dbc, $_POST['first_name']);
} else {
// Add error-message to array.
$reg_errors['first_name'] = 'Please enter your first name!';
}


All day when I typed in a two letter answer - to speed up typing and testing - things worked fine, but now I get a built-in error message off to the side of the input box.

I typed 'ee' and that always worked before but no luck now.

The Reg Ex hasn't changed.

Could it be that there is a database connectivity issue that is screwing up my RegEx??

If I comment out all of the RegEx stuff then it works and my INSERT works - thanks to AlexWD

i have a simple class which sees if there are any members in the database with the supplied details, then returns a simple number to show how many results there are, but it isnt working and throwing the error:

Code: [Select]
Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\wamp\www\classTest\classes\user_process.php on line 52
here is the class:

require_once("db_mysql.php");
require_once("./init.php");

class emptyArgs extends Exception 
{ 
function __toString()
{
return "<strong>Empty Arguments</strong>";
}
}

class user_process
{
public $user_name;
public $password;

public function login($user_name, $password)
{
try
{
if (empty($user_name) || empty($password))
{
throw new emptyArgs();
}

if ($user_name == "")
{
throw new emptyArgs();
}

}
catch (emptyArgs $e)
{
echo $e;
echo "<p>Please Supply All Details Marked *</p>";
}

echo $user_name;
echo $password;

$query = <<<QUERY
SELECT COUNT(*) 
FROM ".TBL_PREFIX."members
WHERE user_username = '$user_name'
AND user_password = '$password'
QUERY;
$process = mysql_query($query);
$result = mysql_num_rows($process); // Line 52 where the error originates

return $result;
}
}

and here is the call:


$user = new user_process();
$user->login("username", "password");


All of the database details are correct and the values do match in the database. Where am i going wrong?

Note that this class is just for testing and not actually used.

Hi

I.m trying to load an RSS feed from a google calendar. I'm using a script from the w3schools website which works with the demo RSS feeds. I changed the URL to my google calendar and for some reason it can't open the feed. I get an error:

Warning: DOMDocument::load() [domdocument.load]: I/O warning : failed to load external entity

I changed the calendar to a shared one and tried that URL but same result.

I found another script specifically for google calendar feed but same results.

The scripts open with other feeds but not google calendar.

ANy ideas?

Code: [Select]
<?php
//get the q parameter from URL
$q=$_GET["q"];

//find out which feed was selected
if($q=="Google")
  {
  $xml=("https://www.google.com/calendar/feeds/...group.calendar.google.com/private-313f84595f6e8dbfc7dc80f450d3e8be/basic");
  }
elseif($q=="MSNBC")
  {
  $xml=("http://rss.msnbc.msn.com/id/3032091/device/rss/rss.xml");
  }

$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
I removed the unique id for the calendar for now

Any help appreciated

Good evening!

i am using PHRETS ( http://dangodesign.n...h-rets-for-php/ ) to pull data off of a MLS RETS server.  i am successfully connecting to the server so the conditional is passing.  but my queries are pulling no results.  the provider tells me DMQL2 is the database. ive only ever worked with MySQL so im in the dark.

adding photo,Array ( [name] => profilepic.jpeg [type] => image/jpeg [tmp_name] => C:\xampp\tmp\phpB923.tmp [error] => 0 [size] => 152127 )

Hi,

We have been using this code for ages, but suddenly for some reason we cannot upload an image using the code below.

When we try to Print_r the $profilephoto variable, I get this error.

The filename is correct, but what is that [error]??  And how do I resolve it?

Oddly it does upload it locally, but LIVE, it won't 

This is the code.

if (isset($updatephoto))
{
echo "adding photo,";
print_r($profilephoto);
 define ("MAX_SIZE","5000");
 function getExtension($str) {
         $i = strrpos($str,".");
         if (!$i) { return ""; }
         $l = strlen($str) - $i;
         $ext = substr($str,$i+1,$l);
         return $ext;
 }

 $errors=0;

 if($_SERVER["REQUEST_METHOD"] == "POST")
 {
    $image =$_FILES["profilephoto"]["name"];
    $uploadedfile = $_FILES['profilephoto']['tmp_name'];

    if ($image) 
    {

        $filename = stripslashes($_FILES['profilephoto']['name']);
        $extension = getExtension($filename);
        $extension = strtolower($extension);


 if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
        {
            echo "Unknown Extension..!";
        }
        else
        {

 $size=filesize($_FILES['profilephoto']['tmp_name']);


if ($size > MAX_SIZE*1024)
{
    echo "File Size Excedeed..!!";
}


if($extension=="jpg" || $extension=="jpeg" )
{
$uploadedfile = $_FILES['profilephoto']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);

}
else if($extension=="png")
{
$uploadedfile = $_FILES['profilephoto']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);

}
else 
{
$src = imagecreatefromgif($uploadedfile);
echo $scr;
}

list($width,$height)=getimagesize($uploadedfile);
$newwidth=600;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);

imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
$pic=($_FILES['profilephoto']['name']);
$random = (rand()%99999999);
$newname="$random"."$pic";
$filename = "images/profiles/". $newname;
imagejpeg($tmp,$filename,100);
imagedestroy($src);
imagedestroy($tmp);
}}
}
$query = ("UPDATE users SET profilephoto =:newname WHERE id =:userid");
$result = $pdo->prepare($query);
$result->execute(array(':userid' => $userid, ':newname' => $newname));
echo "<script>
          window.location.replace('/profile/')
          </script>";}

 

Can anyone explain this?

Warning: get_browser() [function.get-browser]: browscap ini directive not set in /home/albany/public_html/players_dir/dirupdate.php on .....

I'm trying to determine the browser so I can juggle my html a little bit.

Hello everyone:   I'm having trouble with code that compares a Form value ($uname) to Field values (username) from my database. In testing, I'm using the same Form data over and over, and I now have several identical records instead of just one unique record for this user.

  if (empty($_POST["uname"])) {
    $unameErr = "* Username is required";

  } else {
    $uname = test_input($_POST["uname"]);
    if (!preg_match("/^[a-zA-Z0-9]*$/",$uname)) {
      $unameErr = "* Only letters and numerals are allowed";

  } else {
      // Now sure the username is legit, we check to see if it's a
      // unique username by comparing it to all usernames already in member table.

      require_once 'login.php'; // This file contains database access credentials

      $db_conn = new mysqli($db_hostname, $db_username, $db_password, 'login');
      if($db_conn->connect_error) die ('Connect Error: ('.$db_conn->connect_errno.')'.$db_conn->connect_error);

      $query = "select username from member"; // Only selecting the field to compare to
      $result = $db_conn->query($query);
      if(!$result) die ('Database access failed: ('.$db_conn->connect_errno.')'.$db_conn->connect_error);	    

      $rows = $result->num_rows;
      for($i = 0; $i <= $rows; $i++) {
        if(mysqli_fetch_assoc($result) == $uname) { 
	$unameErr = "* Username already in use. Please choose another.";
	mysql_close($db_conn);
	exit;			
        }
     }
     $query = "insert into member values(NULL, '$uname', '$pwd1', '$fname', '$lname')";
     $result = $db_conn->query($query);
     if(!$result) die ("Database insertion failed: ".mysql_error());
    }
  }

This is my first attempt at this using PHP and am pleased that I can at least access my db. But I just can't figure out how to make this comparison check.   Thanks in advance for any help you offer.   ~Landslyde

Morning all, I'm trying to query a user table and am receiving errors. In the mysql statement I am trying to SELECT all data from the table that matches the username of the person logged in.

The error I am receiving is this: Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\123\myaccount.php


The database query is written correctly, if I am logged in as the user Admin then I recieve this message as well:
Unknown column 'Admin' in 'where clause' from the or die(mysql_error());.

In the database the username is: admin but I can login using Admin, is this an issue of upper and lowercase?

The PHP code is below:
Code: [Select]
<?php
require_once('connect.php');

$query = mysql_query("SELECT * FROM user WHERE username = $_SESSION[gatekeeper]");
while ($row = mysql_fetch_array($query) or die(mysql_error()));
{
echo"<div class='BlockContent'>";
echo" <table id='UserList'>";
echo" <tr>";
echo"   <th>My Account</th>";
echo" </tr>";
echo" <tr>";
echo"   <td id='left'>";
echo"   </td>";
echo" </tr>";
echo" </table>";
echo"</div>";
}
?>

This works:
$result = mysql_query("SELECT * FROM mydatabase WHERE username = 'billybob'");

This does not:
$user = "billybob"
$result = mysql_query("SELECT * FROM mydatabase WHERE username = $user");

Shouldn't these be identical?  If I echo $user, I get, of course, "billybob", so does anyone know why the variable isn't working in the query itself?

Hi there

I have a PHP file that works perfectly when I run it in my browser (compiles a report and saves it to my server), however when run from Cron gives a totally different output. Below is the code, and below that is the output I get when run from Cron.

<?php
include("db_conn.php");
