PHP - An Extremely Simple Problem With Functions.
Hello all, I finally started learning php and with the little knowledge I have from CPP it's far simpler than it seemed years ago. I need a little bit of help with this function I followed in a tutorial and it's just not working.
<?php function writeName($fname) { echo $fname . " Refsnes.<br />"; } echo "My name is "; writeName("Kai Jim"); echo "My sister's name is "; writeName("Hege"); echo "My brother's name is "; writeName("Stale"); ?> It just gives me a blank screen. Now, I figured #fname isnt set, so I did this: <?php $fname = "Refsnes"; function writeName($fname) { echo $fname . " Refsnes.<br />"; } echo "My name is "; writeName("Kai Jim"); echo "My sister's name is "; writeName("Hege"); echo "My brother's name is "; writeName("Stale"); ?> Still, no go, which leads me to think I'm probably mistaking. Help? I don't want to skip out things in a tutorial. Similar TutorialsCan someone explain to me whats wrong with this? <?php session_start(); // store session data $_SESSION['views']=1; ?> <html> <body> <?php //retrieve session data echo "Pageviews=". $_SESSION['views']; ?> </body> </html> The output it gives me in the browser is this: Quote Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at D:\Program Files\xampp\xampp\htdocs\sessions.php:1) in D:\Program Files\xampp\xampp\htdocs\sessions.php on line 2 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at D:\Program Files\xampp\xampp\htdocs\sessions.php:1) in D:\Program Files\xampp\xampp\htdocs\sessions.php on line 2 Pageviews=1 Explanation? Hi all. What am I doing wrong here? I cannot read from the file with fopen, this is the code. <html> <body> <?php $file=fopen("welcome.txt","r"); ?> </body> </html> I get a blank page, although I have text written in that file. Whenever I set it to "w" it still shows nothing - when I check the file manually with notepad, I see that it's blanked - but I think thats meant to happen, after all "w" clears the file. Have I understood correctly? This still shows a blank page, but it says it can't find the file if it's not in the directory - how it should be. <html> <body> <?php $file=fopen("welcome2123.txt","r") or exit("Unable to open file!"); ?> </body> </html> tl;dr - Why doesn't fopen read anything from the txt file? Encodings match - everything is in UTF-8, although I doubt thats the problem... Help? Hello, i am trying to create a simple funtion that i can all upon to "turn off a website" i am calling the function by <?php siteonline(n); ?> and the function is function siteonline($msg){ $offlinecheck = mysql_query("SELECT * FROM acp") or die(mysql_error()); $siteoffline = mysql_fetch_array($offlinecheck); $ifsiteoffline = $siteoffline['site_offline']; $offline = $siteoffline['offline_msg']; if ($ifsiteoffline == "y") { echo("$offline"); die();} } now this will turn off the site but it shows no message what so ever and i can not figure out why can anyone help? Cheers, Okay, I have no idea how this works out but this is really getting on my nerves. Here is my logic for the following code. I manually register a user, It goes into the database and dispatches an email notification explaining that a user must activate their account and change their user name (OPTIONAL) and password. In the email, There is an automatically generated password with the username, And a link to activate the account. This leads to stage 1 of the activation process, In this stage the user is accepted, Registered as a verified user and then is sent to another page to change the details like login and password. As far as I know this page works except through trial and error I found that this little snippet of code is causing browsers to show an error 500 page, If I remove this the page works: <?php if($messages){ displayErrors($messages); } else { echo("<p align=\"center\" class=\"standard\">Your account has been activated.</p><p align=\"center\" class=\"standard\">You now need to change your password. If you like you can also change your username, Remember that you only have 3 days to do so and this change will be permanent.</p>"); } ?> and this is the displayErrors function: <?php function displayErrors($messages) { print("<p align=\"center\" class=\"standard\">"."<b>There were problems with the previous action:</b>\n<ul>\n"); foreach($messages as $msg){ print("<li>$msg</li>\n"); } print("</ul>\n"."</p>"); } ?> The displayErrors function is in a file called functions.php, Which is included in config.php, Which is included in every page including this one. The entire "Change password and login page thingie" is he <?php include("config.php"); global $link, $messages; require_once('recaptchalib.php'); if($_GET['error']){ $id=$_GET['id']; $messages[]="There is more than one or no accounts with the verification code you are using. <a href=\"mailto:rentals@nivso.co.uk?subject=Two or no accounts with activation ID of $id\">Click here to email us about this and have the problem sorted.</a>"; doIndex(); exit; } if(isset($_POST['submit'])){ if(!isset($_POST['activationid'])){ die("Doesn't exist -.- might as well quit this is *STUFF* -.-"); } $privatekey = "YOUR NOT HAVING THIS"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { $messages[]="The code you entered is incorrect. Please go back and try again!"; doIndex(); exit; // exit or the below lines will be processed. } else { //This is where the fun starts! $login=$_POST['login']; $passw=$_POST['password']; $passc=$_POST['passwordc']; $id2=$_POST['activationid']; $changinglogin=false; $get1=excDB("SELECT * FROM `users` WHERE `activeID`='$id2'"); if($get1[0]){ $get1=$get1[1]; } else { die($get1[2]); } $pro1=mysql_fetch_array($get1); if($pro1['login']!=$login){ $changinglogin=true; field_validator("Login", $login, "alphanumeric", 4, 15); } field_validator("Password", $passw, "string", 6, 20); if($passw!=$passc){ $messages[]="The passwords do not match, Please make sure that the passwords are the same!"; } if($messages){ doIndex(); exit; } $passcl=mysql_escape_string($passw); $passen=md5($passcl); if($changinglogin){ $wri1=excDB("UPDATE `users` SET `login`='$login', `password`='$passen', `passchange`='1', `loginchange`='1' WHERE `activeID`='$id2';"); if($wri1[0]){ $wri1=$wri1[1]; } else { die($wri1[2]); } header("Location: login.php?created"); } else { $wri1=excDB("UPDATE `users` SET `password`='$passen', `passchange`='1', `loginchange`='0' WHERE `activeID`='$id2';"); if($wri1[0]){ $wri1=$wri1[1]; } else { die($wri1[2]); } header("Location: login.php?created2"); } } } else { doIndex(); } function doIndex(){ ?> <!DOCTYPE html> <head> <title>Family Rental System!

I'm sorry if it is a really simple problem I missed out that makes me look like a right idiot and wasted your time, but that's me I'm always missing stuff out like that, I do proof read though just sometimes not good enough. Thanks in advance! Hi Guys Simple question. Can anyone tell me why this doesn't work please? Code: [Select] $test = "<HEELOOOO"; $test2 = filter_var("$test", FILTER_SANITIZE_STRING); echo $test2; When I run this get I get nothing echoed back, not even in the source. So can the filter function not be used like this? I thought it would encode the special character and return it but I must be missing something simple here! Thanks, Drongo Hi i have a function strored in a seperate file (included in my main php page for use), my question is a simple one but i cannot seem to find the answer on the web to this: I call the function as follows passing the variable $name <?php myfunction($name) ?> The function does somehting simple such as: <?php function myfunction ($name) { if ($name = 'bob') { return true; } else return false; } ?> How do i then obtain the true or false value of the function from back with my main php page? I'm calling a function that resets a couple arrays: public function resetStuff() { $this->someArray = array(); $this->someOtherArray = array(); } However, someOtherArray is not resetting!! How could that be? I can add debug statements to echo the size of the arrays before and after the function calls. It shows that: someArray went from n to 0 someOtherArray went from n to n How is that possible?? We are toying with the idea of using PHP to do sorting instead of our database to reduce load and scale. Basically what we would have is multidimensional arrays that are resturned from the SQL engine and we will need to sort them on a specific key in PHP. We have written this functionality, but are looking to make it faster ANYWAY possible. Do you guys see anyway to speed up this code, without throwing more hardware at the problem yet? Currently on our test server this code takes approx 2.4 - 2.6 seconds to execute. We would love others to try this code and report what it takes them to execute. We are shooting for sub 1 second time. Code: [Select] $array = array(); $temp = array(); for($i = 0; $i < 100000; $i++) { $temp['id'] = rand(10000, 99999); $temp['history_id'] = rand(100000000, 999999999); $array[] = $temp; } //// // Start timer //// $mtime = microtime(); $mtime = explode(" ",$mtime); $mtime = $mtime[1] + $mtime[0]; $starttime = $mtime; //// // Actual sort //// usort($array, function($a, $b) { //Compare numbers if ($a['history_id'] == $b['history_id']) { return 0; } return ($a['history_id'] < $b['history_id']) ? -1 : 1; }); //// // End timer //// $mtime = microtime(); $mtime = explode(" ",$mtime); $mtime = $mtime[1] + $mtime[0]; $endtime = $mtime; $totaltime = ($endtime - $starttime); //// // Output execution time //// echo "Executed in: <strong>". $totaltime ."</strong> seconds."; Ive got some like code like this (this is a part of my source, it'll be enough to solve my problem). I've got 4 functions here trying to run them using switch statement, but only the default one is running, why ? Code: [Select] <?php //******PETLJA ZA MENI*******// switch(@$HTTP_GET_VARS["method"]) { case "ShowAdd": GetNewPollDetails(); break; case "AddFinal": AddPoll(); break; case "ShowDelete": GetPollToDelete(); break; case "DeleteFinal": DeletePoll(); break; default: GetChoice(); } function GetChoice(){ ?> <ul> <li><h2><a href="managepoll.php?method=ShowAdd">Dodaj anketu</a></h2></li> <li><h2><a href="managepoll.php?method=ShowDelete">Izbrisi anketu</a></h2></li> <li><h2><a href="managepoll.php?method=DeleteFinal">Pregledaj ankete</a></h2></li> </ul> <?php } ?> <?php function GetNewPollDetails(){ ?> <h1>Nova anketa</h1> <form name="DodajAnketu" action="managepoll.php?method=AddFinal"> <br /> Pitanje Ankete:<input name="text" type="text" width="150"/> <br /> Odogovor 1:<input name="text2" type="text" width="150"/> <br /> Odogovor 2:<input type="text" width="150"/> <br /> Odogovor 3:<input type="text" width="150"/> <br /> Odogovor 4:<input type="text" width="150"/> <br /> Odogovor 5:<input type="text" width="150"/> <br /> <input type="submit" value="Napravi" name="napravi" /> </form> <?php } ?> I have a script I am putting together that simulate a cricket game. The only issue is, that there are a huge number of functions because there doesn't seem to be any other way to do this properly. As well as this, there a while() loop and all this seems to be leading to the page reaching a max 30 second timeout when generating the result. My code is attached below, it is quite messy at the moment because i've just be working on it, but I was wondering if anyone has any solutions of how I can speed this up or change to prevent a timeout: <?php // Error reporting error_reporting(E_ALL);

I am trying to do something like this: Code: [Select] class my_class { function one () { $two = two (); $three = three (); $five = $two + $three; return $five; } function two () { $two = 2; return $two; } function three () { $three = 3; return $three; } } Unfortunately, I keep getting an error message saying that my call to two () is an undefined function. I am gathering from this that the scope of one () is not aware of the existence of two (). Is there a way to get around this so I can call two () and three () from one ()? It shouldn't be that difficult I just don't know how to do it myself. I'm using the following code for a simple navigation, i has been placed in the content of my home page, it works fine however i don't know how to set the home page. <div id="content"> <?php $page = $_GET['page']; $file = $page.".php"; if(file_exists($file)) { include($file); } else { include "error.php"; } ?> </div> This is my website: www.wearenip.com/home.html This is the menu that should appear on the left hand side, but doesn't: www.wearenip.com/menu.php This is my server's output saying that php is running just fine: http://wearenip.com/phpinfo.php I'm using this code in the left side bar div: Code: [Select] <?php include("menu.php"); ?> The PHP file will not display from the HTML file no matter what I do. I've tried using every possible combination of file linking including /menu.php ./menu.php and even the full http://www.wearenip.com/menu.php etc etc etc I'm genuinely upset about this. Any help would be greatly appreciated. PS: I can't get any PHP file to properly include in any HTML file on any computer I have. Nothing displays whatsoever regardless of what is in the PHP file, even if it's just a text word. Doesn't matter if it's hosted on a PHP compatible internet server or just on a local server or just on the local machine itself. Nothing. SOLVED, sorry. ... but i can't work it out. all i want to do is; if ( $this_item exists within the table ) { do a } else { do b } for example, $this_item = 'john', and i want the script to do (a) if he's in the table, or (b) if he isn't. thank you! so I have an xml string the following expression $xpath = $response->xpath('/atom:feed/atom:entry/atom:content'); returns the following array SimpleXMLElement Object ( [@attributes] => Array ( [type] => application/vnd.google-earth.kml+xml ) [Placemark] => SimpleXMLElement Object ( [name] => M1 [description] => SimpleXMLElement Object ( ) [Style] => SimpleXMLElement Object ( [IconStyle] => SimpleXMLElement Object ( [Icon] => SimpleXMLElement Object ( [href] => http://maps.gstatic.com/intl/en_ALL/mapfiles/ms/micons/blue-dot.png ) ) ) [Point] => SimpleXMLElement Object ( [coordinates] => -79.395018,43.645423,0.0 ) ) ) However what I'm trying to get are the coordinates, but neither $xpath = $response->xpath('/atom:feed/atom:entry/atom:content/Placemark'); OR $xpath = $response->xpath('/atom:feed/atom:entry/atom:content/Placemark/child::*'); work I even tried just loading atom:content into an array and going from there no luck. Any ideas. Oh. BTW this might help http://code.google.com/apis/maps/documentation/mapsdata/developers_guide_protocol.html#RetrievingFeatures Ok I got this column "date_reg" on my table which has a "datetime" type. It's giving me a value like "2012-04-20 04:28:03" The problem is, when I'm trying to insert on that column using this format Code: [Select] <?php $datenow = date('m/d/Y h:i:s a', time()); ?> it's giving me a value of "0000-00-00 00:00:00" which is suppose to be the current date and time the user add on that table. Anyone knows how I can fix this? Hi! I'm a little bit new to php and i'm having a stupid issue here with mysql_real_escape_string. I have a really simple text input field into an html form and I want to save the data into a SQL table. Sometime I'm trying to insert a name with a quote like : steve's ..So I escape the text with mysql_real_escape_string but the problem is that there's a \ also inserted into the DB (steve\'s)... Is there anyway to get rid of that? Thanks in advance! Hi, This is a image tooltip from database. but I have got the problem, Not Working!

Here is the problem - I have one script wherein I have a form that passes a variable using Post method. I have previously assigned a value "A" to a variable $rtn the input is: <input name="Rtn" type="hidden" value="<?php echo $rtn; ?> /> In the script that I am calling I first get the value of the variable: $rtn = (_POST['Rtn']); then there is other stuff goin on and I come to an if stmt: if ($rtn == "A" { do some stuff } else { echo $rtn; } It will never get into the do some stuff - it always falls through to the else the output is \'A\' I have tried to use double quotes, single quotes, used stripslasches and addslashes funtions, trim, and various combination of all of these. Nothing I do seem to get me into the first part of the if stmt, to do some stuff. |
