PHP - No Ending Delimiter '^' Found In ...

I am trying to split a variable only if it has an integer. Here is what I want to do:

$id = 1234-54678;

should be split into and then placed into two variables:

$id1 = 54678;
$id2 = 1234;

Sometimes the variable may not have a delimiter in which case I would like it to be $id1

example:
$id = 54678;

should go directly to

$id1 = 54678;

I am a php rookie and don't know which way is best to do this (explode, split, etc.) so I would appreciate any help you can give me.

I am working on taking out the Deprecated functions from my site so while replacing ereg with preg_match I get the below error. Per a message I found on the internet it says to replace ereg with preg_match and everything should work. Can anyone assist me with fixing this error?

Hey guys. I am trying to strip everything between a key phrase and ending tag but for some reason it is not working. I always get blank data. I've tried many different ways but no luck.   basically I have a script that connect to imap and store emails into MySQL as service tickets. works great but I am trying to strip everything except for user reply because currently if a user reply to an email it re-inserts the entire email into MySQL. I added a key phrase at the top of all outgoing emails .   1. structure looks like this.   --Reply below this line to respond-- ------------------------------------------------------------------------------------------------   Email body message...   2. When replying to the message it becomes   New Message reply......   --Reply below this line to respond--   old message body.     3. so I would only like to insert the new reply message only.     This is what I got so far.       $message=strip_tags($message, "<br><div><p><u><hr></section>");       $message=preg_replace("</p>", "br /", $message);
   
    $message=preg_replace('#--REPLY above this line to respond--(.*?)</section>)#s', ' ', $message);
   
    $message=clean("<br/><hr><u>Received On $rep_date / $from_email</u><br><br/>$message");     it inserts the "Received On date and From but $message is blank.   If i remove $message=preg_replace('#--REPLY above this line to respond--(.*?)</section>)#s', ' ', $message);  it inserts the entire email   Any suggestion on what i am doing wrong?   thank you all very much.  

Hello,

I have the $_session code working, but after I destroy the session and I am asked to log in again, my browser doesn't ask me for my password and just logs me in.

I don't understand because I have destroyed my session and I have deleted the data in $_SESSION and I have deleted the info in the cookie so it shouldn't log me in automatically. I thought it was something in my browser, but I erased my history and I never saved any password.

Here's my code:

This is the welcome page

<?php
    require_once 'login.php';
    $connection = new mysqli($db_hostname, $db_username, $db_password, $db_database);
    
    if ($connection->connect_error) die($connection->connect_error);
    
    if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW']))
    {
        $un_temp = mysql_entities_fix_string($connection, $_SERVER['PHP_AUTH_USER']);
        $pw_temp = mysql_entities_fix_string($connection, $_SERVER['PHP_AUTH_PW']);
        
        $query = "SELECT * FROM users WHERE username='$un_temp'";
        $result = $connection->query($query);
        
        if (!$result) die($connection->error);
        elseif ($result->num_rows)
        {
            $row = $result->fetch_array(MYSQLI_NUM);
            
            $result->close();
            
            $salt1 = "qm&h*";
            $salt2 = "pg!@";
            
            $token = hash('ripemd128', "$salt1$pw_temp$salt2");
            
            if ($token == $row[3])
            {
                session_start();
                $_SESSION['username'] = $un_temp;
                $_SESSION['password'] = $pw_temp;
                $_SESSION['forename'] = $row[0];
                $_SESSION['surname'] = $row[1];
                
                echo "$row[0] $row[1] : Hi $row[0], you are now logged in as '$row[2]'";
                
                die("<p><a href=continue.php>Click here to continue</a></p>");
            }
            else die("Invalid username/password combination");
        }
        else die("Invalid username/password combination");
    }
    else
    {
        header('WWW-Authenticate: Basic realm="Restricted Section"');
        header('HTTP/1.0 401 Unauthorized');
        die("Please enter your username and password");
    }
    $connection->close();
        
    function mysql_entities_fix_string($connection, $string)
    {
        return htmlentities(mysql_fix_string($connection, $string));
    }
        
    function mysql_fix_string($connection, $string)
    {
        if (get_magic_quotes_gpc()) $string = stripslashes($string);
        return $connection->real_escape_string($string);
    }
?>

and this is the other page:

<?php
    session_start();
    
    if(isset($_SESSION['username']))
    {
        $username = $_SESSION['username'];
        $password = $_SESSION['password'];
        $forename = $_SESSION['forename'];
        $surname = $_SESSION['surname'];
        
        destroy_session_and_data();
        
        echo "Welcome back $forename. <br>
            Your full name is $forename $surname.<br>
            Your username is '$username'
            and your password is '$password'.";
    }
    
    else echo "Please <a href='authenticate2.php'>Click here</a> to log in.";
    
    function destroy_session_and_data()
    {
        $_SESSION = array();
        setcookie(session_name(), '', time() - 2592000,'/');
        session_destroy();
    }
?>

 

When I type the website in i first get prompt to enter my password, when I am authenticated the webpage says: You are now logged in click here to continue. When I do I am directed to another page which confirms that I am still logged in. Then I press refresh and the webpage asks me to "Click here to log in". I do, but it doesn't ask me for my password again. Why? My personal info should be destroyed.

Thank you for responding. It's greatly appreciated

 

 

 

Hi, I am trying to figure out how to stop my script from offering a discount when the date that is listed passes by.  It seems to always 'reset' itself even after the 15th of the month...I want it to stop after April 15...This is what I had, can anyone assist?

Thank you in advance for your help!
Jennifer

Code: [Select]
}


        if(date("n") < 15) {

            $before = $cost*.05;

            $before = round($before,2);

            $cost = $cost-$before;

        }

Hi Everyone,

I wonder if somebody could help me. I have been at this for hours and am really struggling.

I have a timer which I have set up for a quiz.  The quiz opens in a javascript shadow box.  When the quiz is opened a session variable for the timer is set up to keep track of the time. 

What I need is for this session variable to end when the shadow box is closed. I have a onClose hook to peform actions when the shadow box is closed which is in javascript.

Obviously I cannot end the session variable in the javascript function due to js being client side and php being server side.

Has anyone any suggestions how I can resolve this issue.

I need to end this session variable as if the user exits the quiz and then selects another quiz to do the timer uses the current time session rather than assigning the new time value for that particular quiz.

Thanks in advance. 

Edd

Part of my page is taken from external webpages by preg_match. Since It is a partial section, it contains incomplete tags such as <div>, <span>, etc. Thus, they mix up with my entire page and my </div>, </span> are used for the incomplete tags in the borrowed section. How I can end such tags? or separate this section from the main codes (I mean having an isolated section)?
 

Hello happy codes,

I have an image as such;
http://storage.canoe.ca/v1/dynamic_resize/?src=http://www.torontosun.com/specialsections/2011/03/10/248x186_mb.jpg&size=40x30

getimagesize doesn't work with this image.

Any ideas or links? I have looked through this site and can't find anyone having this problem. Am I missing something?

Thank you,

V.

preg_replace() asks that "Delimiter must not be alphanumeric or backslash" in the pattern.  So I changed

 $new_text = preg_replace($_POST['withthis'] ,$_POST['withthis'],$_POST['text']);
to this
$replacethis = $_POST['replacethis'];
$new_text = preg_replace("/$replacethis/",$_POST['withthis'],$_POST['text']);
It works fine, but out of curiosity, is there any way to have the POST variable as a parameter directly, and why does it not work? 

Just to try it, I attempted: "/$_POST['withthis']/"  and $_POST["/'withthis'/"] and both do not work.  str_replace is a better option I think, but I am just trying to get a better understanding of this delimiter rule.  Thanks for your time!

Hi Folks! New to php and introduced into it by a new found  friend who is really into php. Been learning and learning and learning but not so much I am afraid. I guess books and youtubes and other tutorials are not enough so here I am, fearlessly venturing into this forum and I hope to learn much more to all ya pros out there err I mean in here. Be gentle to me please. I am not a coder but I do have logical thinking attitude and habit. I am a slow learner and close to the resignation age. But who cares, I wanna learn php, yeah!

This code works without problems:

<?php
namespace NamespaceA;
class A extends \NamespaceB\B {}

namespace NamespaceB;
class B {}

But why the following code cause Fatal error: Class 'NamespaceB\B' not found in ...file?
 

<?php
namespace NamespaceA;
class A extends \NamespaceB\B {}

namespace NamespaceB;
class B extends \NamespaceC\C {}

namespace NamespaceC;
class C {}

And this code also works without problems:

<?php
namespace NamespaceA;
class A extends \NamespaceB\B {}

namespace NamespaceC;
class C {}

namespace NamespaceB;
class B extends \NamespaceC\C {}

Without any namespace, also Fatal error: Class 'B' not found in ...file:
 

<?php

class A extends B {}

class B extends C {}

class C {}

Works without problems:

<?php

class A extends B {}

class B {}

And yes everything is in the same PHP file....
