PHP - How Either Check Pear Installed Or Catch Include_once Statement?

Hi! I am new to PHP and I googled a lot before coming here.

I have trouble accessing localhost/community/admin/board_functions.php from a folder which path is localhost/community/boards/test/index.php, which script is the one below.

What path should I put on require_once to access the script?

Thanks in advance

Code: [Select]
<?php

require_once "..admin/board_functions.php";

$board_location = explode("\\", __DIR__);

$board_name = $board_location[5];

$board_title = board_title($board_name);

echo $board_title;

?>

I have this code which performs a mysql query.  However is there a way I can check to see if the set it returns is empty.  If it is empty I will then change the sql statement.  Thanks

$announcement_sql = "select * where annnouncement_for like \"%" . $_POST['for_search'] . "%\" and announcement_verification=\"1\" order by announcement_number desc limit 0, 15";

Sorry going to be a big post, but trying to query a sql database for a value

Original code

<?php if($this->item->params->get('catItemExtraFields') && count($this->item->extra_fields)): ?>
     <!-- Item extra fields -->
     <div class="catItemExtraFields">
        <h4><?php echo JText::_('K2_ADDITIONAL_INFO'); ?></h4>
        <ul>
         <?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
         <?php if($extraField->value): ?>
         <li class="<?php echo ($key%2) ? "odd" : "even"; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
            <span class="catItemExtraFieldsLabel"><?php echo $extraField->name; ?></span>
            <span class="catItemExtraFieldsValue"><?php echo $extraField->value; ?></span>
         </li>
         <?php endif; ?>
         <?php endforeach; ?>
         </ul>
       <div class="clr"></div>
     </div>
     <?php endif; ?>


Now I want to check the name field for a value and if it is Closing Date print out something different from the value in value, so I've changed the red code to

<span class="catItemExtraFieldsLabel"><?php if $extraField->name ="Closing date"; ?></span>
            {
            <span class="catItemExtraFieldsLabel"><?php echo $extraField->name; ?></span>
             <span class="catItemExtraFieldsValue"><?php echo $this->item->publish_down, JText::_('K2_DATE_FORMAT_LC2')); ?></span>
                }
                else
                {
                <span class="catItemExtraFieldsLabel"><?php echo $extraField->name; ?></span>
            <span class="catItemExtraFieldsValue"><?php echo $extraField->value; ?></span>
                }
            <?php endif; ?>

Doesn't work though, tried a heap of variations but can't figure it out.

Thanks

Say you have three tables like this...   STUDENTS (studentid, name)   CLASSES (studentid, classname)   GRADES  (studentid, grade)   And not all students have grades yet.  If you're doing a mysql query like below, is there anything you can add to the statement to check if a grade exists for each student?   So that if while lopping through the results of the main query, I can easily do something with the students who don't yet have a grade yet (like maybe mark their names in red).   I can do this by putting a whole separate mysql query inside the looping of the main query, but that seems terribly inefficient to call the database again for EVERY student.

$sql = "SELECT * FROM students, classes, grades
	WHERE students.studentid = classes.studentid
        ORDER BY students.lastname";
	$info= mysqli_query($connection, $sql);
	if (!$info) {
	die("Database query failed: " . mysqli_error());
	} else {
           //code
        }

Thanks! Greg

Is there any way to catch warnings without defining a warning handler?
Example:
try
{
$settings = parse_ini_file( 'main.ini' );
}
catch( ErrorException $e )
{
throw new ErrorException('No main configuration file found for webiste', '0003');
}


Only ends up throwing a warning if the file doesn't exist. I want to catch it and throw an error.

i keep getting this error Fatal error: Uncaught OAuthException: Error invalidating access token: Session does not match current stored session. This may be because the user changed the password since the time the session was created or Facebook has changed the session for security reasons. thrown in /home/sites/socialnewsoffice.com/public_html/sm-login/social-media-connect/facebook/base_facebook.php on line 1050

how can i catch and display this warning to the user?

Hello guys.

Is it possible to catch a fatal error and then do something?

What I need to do is to catch the error and run the script a second time, before the first execution ends.

Kind regards and thanks for advance.

Hey Guys. I am across this in a book and I am having a hard time understanding how I can try/catch this expception   The code below will throw an exception if I add an unit object into Archer or LaserCannon object.   Here is a quick example

class UnitException extends  Exception{}

abstract class Unit{



    function AddUnit(Unit $unit){
        throw new UnitException(get_class($this)."is a leaf");
    }
    function removeUnit(Unit $unit){
        throw new UnitException(get_class($this)."is a leaf");

    }

    

    abstract function bombardStrength();


}

class Archer extends  Unit {
    function bombardStrength(){
        return 4;
    }
}




class LaserCannonUnit extends  Unit {
    function bombardStrength(){
        return 44;
    }
}

$laser_cannon = new LaserCannonUnit();
$laser_cannon->AddUnit(New Archer()); // This is not allowed

When I run the client code I get the following error message   Fatal error: Uncaught exception 'UnitException' with message 'LaserCannonUnitis a leaf'   Can any please help me understand this?? Thanks!

So I'm debating whats the best method. I'm aware that catch/blocks should be used in exceptional cases but what if it saves me from having 4 nested if/else conditions? The following is code for an xbox registration site
Code: [Select]
try {
    // check code is valid
    $c1 = $this->input->post('code1',true);
    $c2 = $this->input->post('code2',true);
    $c3 = $this->input->post('code3',true);
    $gt = $this->input->post('gamertag',true);
    $pass = $this->input->post('password',true);
    if(
    $c1 == '' || $c2 == '' || $c3 == '') {
        throw new FormError("Authorization code invalid.");
    }
    // check db for code validation
    $q = $this->db->query("select * from `codes` where `activated` = 0 and `code` = ".$c1.$c2.$c3." limit 0,1");
    if($q->num_rows() != 1) {
        throw new FormError("Authorization code invalid.");
    }
    $r = $q->row_array();
    $email = $r["recipient_email"];
    $codeGt = $r["gamertag"];
    // check valid gamertag
    $q = $this->db->query("select * from `users` where `gamertag` = '".$gt."'");
    if($q->num_rows() > 0) {
        throw new FormError("Gamertag already exists.");
    }
    // validate gamertag /w inputted gamertag
    if(strtolower($codeGt) != strtolower($gt)) {
        throw new FormError("Gamertag Invalid");
    }
    $this->_createAccount($email,$pass,$gt);
    // show register-thanks screen
    $this->load->view("register-thanks",$data);
    $success = true;
} catch (Exception $e) {
    $data['error'] = $e->getMessage();
}

I have the code below working perfectly, but I was wondering if there is a more eloquent way to write this, specifically handling the exceptions...

This creates an object of a Router Class that parses my clean URLs into a Controller name, method name and the rest are arguments.

So for example: www.domain.com/users/view/profile/bobsmith would route to the Users Controller, and find the viewUsers
method and pass the arguments "profile" and "bobsmith" to it, and the method would take it from there... works great.

That explains what this code does. My only question is if there is a cleaner way to handle the exceptions, so I don't have
"throw new exception" written four times. Thoughts? Or is it good to go?



$rawURL = getPageURL();
$router = new Router($rawURL,$rootDIR);
$controller = $router->getController();
$method = $router->getMethod();
$arguments = $router->getArguments();

try {
// check controller exists and set controller path //
if ((isset($controller) && ($controller != ''))) {
$controllerPath = APPLICATION_PATH . "controllers/" . $controller . ".class.php";

// check controller path exists //
if (file_exists($controllerPath)) {
    
// set method name and check method exists //
if ((isset($method) && ($method != ''))) {
$methodName = $method . ucfirst($controller);

if (method_exists($controller, $methodName)) {
// test it out //
$test = new $controller();
$response = $test->$methodName($arguments[0]);
echo $response;
}
else {
// method_exists failed //
throw new Exception("That method does not exist foo!");
}
}
else {
// method was not found in URL //
throw new Exception("No method name was given foo!");
}
}
else {
// file_exists failed //
throw new Exception("That controller does not exist foo!");
}
}
else {
// controller was not found in URL //
throw new Exception("No controller name was given foo!");
}
}
catch (Exception $e) {
// spit it out foo //
echo $e->getMessage();
}

Hello,

I'm fairly new to PHP, and I'm trying to get the GD2 library working but I am having no luck. I have installed the library, and when I run phpinfo(); it shows that it is up and running, and all file types are supported. However, when I run the following code snippet nothing is displayed:

<?php
  $im = @imagecreate (200, 100) or die ( "cannot create a new gd image.");
  $background_color = imagecolorallocate ($im, 240, 240, 240);
  $border_color = imagecolorallocate ($im, 50, 50, 50);
  $text_color = imagecolorallocate ($im, 233, 14, 91);
  imagerectangle($im,0,0,199,99,$border_color);
  imagestring ($im, 5, 10, 40, "a simple text string", $text_color );
  header ("content-type: image/png");
  imagepng ($im);
?>

I have been struggling with this for a couple of weeks now with no luck. Any help would be greatly appreciated.

I just installed XAMP on my windws pc.

When I try to launch my index.html file, I only get this output:

Hello World";?>

This is not correct...

My index.html file consists thrse lines:

<html>
 <head>
  <title>PHP Test</title>
 </head>
 <body>
 <?php echo "<p>Hello World</p>";?>
 </body>
</html>

 

What is wrong?
Thanks in advance...

When I put all my code in one file, everything runs smooth, as soon as I try to put a chunk of code in a separte PHP file and use an include or require_once I get the error Assigning the return value of new by reference is deprecated in...PEAR\config.php yadda yadda

I've done some research and I understand that passing an object by reference (&obj) is no longer acceptable in PHP 5, that's fine, but no where in my code do I have an ampersand, and again, it all works fine if it's all in the same .php file. So i figure i might be doing something wrong with my includes or something.

The errors that I am getting are

Deprecated: Assigning the return value of new by reference is deprecated in C:\xampp\php\PEAR\Config.php on line 80

Deprecated: Assigning the return value of new by reference is deprecated in C:\xampp\php\PEAR\Config.php on line 166

Deprecated: Assigning the return value of new by reference is deprecated in C:\xampp\php\PEAR\Config\Container.php on line 111

Code: [Select]
include('config.php');
connect();

while ($row = mysql_fetch_assoc($ran_result)) {
    $ran_image = $row['image'];
    $category = $row['category'];
    $last = $row['l_name'];
    $first = $row['f_name'];
    $return = $row['item_return'];
}

echo "<div id='random'>\n";
echo "<h1>Random Signatures</h1>\n";
echo "<img src='../auto_images/$ran_image' /><br />\n";
echo "<p><a href='../auto_pages/signatures.php?c=$category&l=$last&f=$first'>$first $last</a></p>\n";
echo "<p>$return</p>\n";
echo "<br>";
echo "</div>";
?>
Am I doing something wrong with the include?

Hi all,

Will reading on php.net about the famous mail() function somewhere in the notes, the author mentions to use Pear:: for sending larger amounts of email.

Since I have never done anything with pear, I was wondering if it weren't better to start out with Pear, since it's more a long term thinking solution or shoudl i first start  with mail().  I have read the Pear pagess, and all I saw were delayed mail sending and sending in larger quantities. If someone could maybe advise me on would could be a best practise i would love to hear
