Hi guys
I get this warning when testing out code in xampp Warning: Division by zero in C:\xampp\htdocs then it continues; Warning: Division by zero in C:\xampp\htdocs\TFN\index.php on line 25 Warning: include(C:\xampp\php\PEAR\PHP) [function.include]: failed to open stream: Permission denied in C:\xampp\htdocs\TFN\index.php on line 25 Warning: include() [function.include]: Failed opening 'php' for inclusion (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\TFN\index.php on line 25 Warning: Division by zero in C:\xampp\htdocs\TFN\index.php on line 27 Warning: include(C:\xampp\php\PEAR\PHP) [function.include]: failed to open stream: Permission denied in C:\xampp\htdocs\TFN\index.php on line 27 Warning: include() [function.include]: Failed opening 'php' for inclusion (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\TFN\index.php on line 27 ...... I have used the search function but all the results are similar but i cant find one that fits/ solves my issue hence the new thread, so apologies in advance. Please note im trying to get to grips with php and i havent done any wed design in 10 yrs or so, so bear with me if i seem idiotic at times lol i followed this basic tutorial from he http://www.1stwebdesigner.com/css/how-to-create-php-website-template/ Then was going to edit / add as needed but after getting to the final stage and testing it... The above error appeared. so u can see what i see here is a link to my site: http://tfn.site11.com/ here is my folder/file structure root css folder/ css file includes folder/ footer.php/header.php/nav.php/sidebar.php variables folder/ variables.php index.php If you need to know anything else just ask.. Thanks for your time Similar Tutorials

Edited March 28, 2020 by Ben555 Hi Everyone I am having a few issues with my website. I have developed in on my xampp local host and it works ok but when I upload the files and try to renew a membership using stripe I get the following messages. Warning: session_start(): Cannot start session when headers already sent in /customers/a/d/f/mywebsite.co.uk/httpd.www/mywebsite/inc/settings.php on line 2 Warning: Cannot modify header information - headers already sent by (output started at /customers/a/d/f/mywebsite.co.uk/httpd.www/mywebsite/procedures/payments/charge.php:1) in /customers/a/d/f/mywebsite.co.uk/httpd.www/mywebsite/procedures/payments/charge.php on line 141 I have some includes that appear on every page. This is the bootstrap.php file. This file holds the settings.php which connects to my database and other function files. In this settings page I call the session_start() php function and then connect to my database. I call the bootstrap.php file on every page to there for call the session_start() on every page. I am using sessions alot so is this the right thing to do? I have attached the renew_membership payment page which holds the form. The user fills out the payment page and the form data gets sent to a script called charge.php which uses the stripe objects to make the payment. I then want to do a redirect to the paymentSuccess.php page to output to the user that the payment was made successfully. This is where the issues arrise. I have split the charge file into 3 screen shots so it is more readable. Hope someone can help me. Thanks a lot David

Edited by mac_gyver, 09 October 2014 - 10:51 AM. code in code tags please I am running to an issue that I have never delt with before and am not sure if there is even a possible solution: I have two files: fileA and fileB fileA contains a loop that loops 30 times each time its called. in the loop there is a 2second delay $i = 1; do { $i++; sleep(2); if(!isset($_SESSION['user']) { break; } } while($i < 31); if fileB i have a simple destroy session $_SESSION = array(); session_destroy(); I call both files via ajax, and that is where i run into my problem. if I call fileA first, then call fileB through ajax, the code in FileB does not execute until fileA has run its course. Is it possible to get around this? Like set the priority of one over the other? So, this is something that I've been wondering for a while now... say you have two variables that you need to divide to find a certain percentage and one happens to be zero... why does PHP feel the need to return a warning saying there was a division by zero? why not just return the number zero since anything that's divided by zero always results in zero anyway? Just a random thought. if($ns_cb->targetCurrency == 'USD') { $usd_base_rate = '1'/$ns_cb->value; } $eq = number_format($usd_base_rate*$ns_cb->value,2); echo $eq $ns_cb->value is currently = 0.9940. But this gets updated every day. I keep getting division by zero for this problem here, any help? hey guys i'm trying out this ajax rating script and i get this division by zero: Warning: Division by zero in /home/open2sha/public_html/Rate/index.php on line 37 <?php // very quick & dirty code $sql = mysql_query("SELECT * FROM tut_starRating"); $rows = mysql_num_rows($sql); if ($rows == 0) { echo "no rows found"; } else { while($row = mysql_fetch_array($sql)) { $tmp_rating = $row['rating'] / $row['votes']; $rating = round(($tmp_rating*2), 0)/2; // round up or down to nearest half print("<li><div class='rating' id='rating_".$row['articleId']."'>".$rating."</div><div id='starRatingFeedback_".$row['articleId']."'></div></li>"); } } ?> </ol> Well, I am currently working on a Kill/Death Table when the players insert there kills and deaths along with a screenshot of proof. I have got most of it down except for a Warning: Division by zero in /home/a2186214/public_html/table/index.php on line 43 error. This is the code I am using to calculate the kill/deaths: Code: [Select] if ($row['kills'] >= 1) { $kdr = $row['kill']/$row['death']; } elseif ($row['death'] >= 1) { $kdr = $row['kill']/$row['death']; } else $kdr = '0';How would I fix this? Hi can any body give me an idea why i am receiving the following errors from my script?

Everything worked well on my localhost(xampp server) and when i uploaded on dedi machine functions with MySQL database stoped working. Problem was with mysql_real_escape_string and i forgot that i must first open connection and then mysql_real_escape_string... But strange thing is that on xampp server i dont need to open connection for mysql_real_escape_string, and everything worked well... is there any solutio to php scripts on xampp worke same as php script on linux apache server? I have a Xampp Timezone Error Error Warning: strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for '-5.0/no DST' instead in C:\Users\cory j\Desktop\xampp\htdocs\NoXIp\Toplist\inc\vote.php on line 56 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' NOW())' at line 1 Line 56 $diffrence = time() - strtotime($getDate['lastVoteDate']); The Date Function in Php.ini [Date] ; Defines the default timezone used by the date functions ; http://php.net/date.timezone date.timezone = "America/New_York" date.timezone = "America/New_York" ; http://php.net/date.default-latitude ;date.default_latitude = 31.7667 ; http://php.net/date.default-longitude ;date.default_longitude = 35.2333 ; http://php.net/date.sunrise-zenith ;date.sunrise_zenith = 90.583333 ; http://php.net/date.sunset-zenith ;date.sunset_zenith = 90.583333 Hey, practicing my PHP for the first time, starting with a simple upload script with Xampp. Script: Code: [Select] $target = '/Uploads'; $uploadedfile = $target . basename($_FILES['file']['name']); if(move_uploaded_file($_FILES['file']['tmp_name'], $target)){ echo "The file ". basename($_FILES['file']['name'])." has been uploaded."; } else { echo 'Failed'; } error_reporting(E_ALL); It echos out a successful, but the file is nowhere? Uploads is inside htdocs. Checked my php.ini file: file_uploads = On upload_tmp_dir = "C:\xampp\tmp" upload_max_filesize = 128M Just wondering if there are any permission i may have missed? |
