PHP - Editing A Xml File Based Upon String Then Assigning To String.
Hey there,
Thanks for taking the time to read my thread. My issue is that I can't think of a way to edit a XML file using PHP's XML functionality and then assign the edited contents to a string instead of saving the file. Because my issue is that I have to edit the XML file based upon a string brought from a remote location then give it back to that remote location using a string again, to be exact I am doing it via Linux command line utilizing SSH2. This is what I managed to complete on my own. function CheckIVMPConfig($ServerID) { global $Panel; if(is_numeric($ServerID) && $this->IsValidServer($ServerID)) { // We select the game server that the FTP account was created for. $Servers = mysql_query("SELECT * FROM control_servers WHERE server_id = '".mysql_real_escape_string($FTPAccount['ftp_server'])."'"); $Server = mysql_fetch_array($Servers); // Here we select the Box ID that the game server is on. $Boxs = mysql_query("SELECT * FROM control_machines WHERE machine_id = '".$Server['server_machine']."'"); $Box = mysql_fetch_array($Boxs); // Now we select the required package for the box. $Packages = mysql_query("SELECT * FROM control_packages WHERE package_id = '".$Server['server_package']."'"); $Package = mysql_fetch_array($Packages); // Retrive the file. $Config = $CProtocol->exec("cat /home/{$Server['server_id']}/{$Package['package_config']}"); $Parse = SimpleXMLElement($Config); foreach($Parse as $Entry) // loop through our books { if($Entry->port != $Server['server_port']) { // edit the value } else if($Entry->maxplayers > $Server['server_slots']) { // edit the value } } } } Similar TutorialsI need to assign unknown array keys and their values to strings. The code I am using is: Code: [Select] $cart = $_SESSION['cart']; $items = explode(',',$cart); $qty = array(); foreach ($items as $item) { $qty[$item] = $qty[$item] + 1; } print_r($qty); The keys change and are not ordered. I do not know what the key or it's value may be. So as an example, I might have: Code: [Select] Array ( [2] => 5 [4] => 8 ) or in a different scenario, I might have: Code: [Select] Array ( [1] => 6 ) What those numbers represent is a product id (the key), and the quantity (the value of the key). Can someone help me to assign these to a string? I have been reading all morning, and not making any progress. Thank you! Given a text value $path, I want to return the actual path. One option is a switch statement as shown below. Another option is put them in an associated array (or maybe a static array?) and check if the element is set and if not throw an deception. Or maybe a totally different solution. Is one solution better (i.e. more efficient) than another? I will probably be retrieving a path around 5 times for every server hit. Thanks
function getPath($path)
{
switch($path){
case 'classes': $path=__DIR__;break;
case 'application': $path=dirname(__DIR__);break;
case 'root': $path=dirname(dirname(__DIR__));break;
case 'twig': $path=dirname(dirname(__DIR__)).'/vendor/autoload.php';break;
case 'lib': $path=dirname(__DIR__).'/lib';break;
case 'help': $path=dirname(__DIR__).'/lib/help';
case 'templates': $path=dirname(__DIR__).'/lib/templates';
case 'htdocs_base': $path=dirname(dirname(__DIR__)).'/html';
case 'resources_base': $path=dirname(dirname(__DIR__)).'/user_resources';
// About 10 more
default: throw new Exception("Path {$path} not valid.");
}
return $path;
}
question here... say we have a string coming from a form, already verified that its numeric/mathmatical(+-*/) how can we then process that into an answer without using eval? Code: [Select] $string='1+2*3'; echo process($string); #7 Quote If eval() is the answer, you're almost certainly asking the wrong question. -- Rasmus Lerdorf, BDFL of PHP Hi, I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads. Here is uploadify.php as it currently looks: Code: [Select] <?php session_name("MyLogin"); session_start(); $targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder; $targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('m4a','mp3','flac','ogg'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } } echo $targetFolder; ?> I added Code: [Select] echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'. For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'. The folder for username exists, with correct permissions, and when I manually enter Code: [Select] $targetFolder = '/songs/nick';all works fine. Which strikes me as rather strange. I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string. Any help would be much appreciated. It's the last issue with a website that was due to go live 2 days ago! Thanks, Nick Hi Folks, This is my first post here and I was wondering if anyone could help me out at all please. I would basically like to change the logo on the home page based on whether a query string from a referring URL has a specific value. It's an affiliate URL for an online store, so essentially I need to get the referrer, check if the query string adnetwork = as and then replace the logo if it does, if not leave it as it is. Does that make sense? Any help would very much appreciated. I was thinking along the lines of: <?php if ($_GET('adnetwork') == 'as') { changeLogo(); } else { leaveLogo(); } ?> Am I along the right lines folks? Hello all, I'm trying to change the end of a javascript call based on the end of the url string. The common part of all the url strings is sobi2Id=, I'm trying to do this with strstr but am having no luck. I'm new to php so my syntax knowledge is terrible! at the moment i've got Code: [Select] <?php $url = $_SERVER['REQUEST_URI']; $tag = strstr ($url, 'sobi2Id='); echo $tag; ?> but this returns an unexpected T_STRING, expecting ',' or ';' Can anyone debug this? I may well be being really silly! This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=326004.0 hey guys im trying to find a string inside a string which could be made up of different things eg... {$test}, {$test1}, {$test2} etc (but the varable inside could be called anything hence maybe using regex im not sure?) is this possible?...i hope you guys understand....thanks I have the following function, which takes a string with commas in it and attempts remove those commas. The way I have it here is that I use explode to take out the commas, which makes an array, and then iterate through that array to put a string back together without the commas. function tags_to_sort_by( $sortMeta ) { $sortByArray = explode(",", $sortMeta); $sortByCount = count($sortByArray); for ($i = 0; $i < $sortByCount; $i++) { $sortByString += $sortByArray[$i]; } return $sortByString; } What does not work is the following line: $sortByString += $sortByArray[$i]; Somehow that outputs a 0, which I don't understand. It should output something like: arrayItem1 arrayItem2 array3 etc. My question is if there either is an easier way to remove the commas from the original string or what I am doing wrong in this line: $sortByString += $sortByArray[$i]; // I am trying to concatenate each part of the array back into the string. Thanks a lot for help with this! Hi Community! :-) (Sorry for my average english) I recently started coding in php, till now, i allready have advanced skills in programming with C# and thus, had no problems writing my own script. Still, my script does not really work, i'm trying to check if a file contains a md5(string), but the script never finds the string. This is the script: (please don't mind any security issues, this is just a test. But if you have any tips and tricks to improve the security, i'd be glad to receive them)
<?php
$webname = $_POST["webname"];
$webcode = $_POST["webcode"];
$webpass = $_POST["webpass"];
if (file_exists("web/". $webname . ".html")) {
$file = file_get_contents("web/". $webname . ".html", "r");
if (strpos(md5($webpass),$file) !== false) {
$usergen = fopen("web/" . $webname . ".html", "w") or die("Unable to open file!");
fwrite($usergen, $webcode);
fwrite($usergen, "<!--- ". md5($webpass) . "--->");
fclose($usergen);
echo "Generated! You can view your site under /web/" . $webname . ".html";
}
else
{
echo "The file already exists but you entered the wrong Password.<br> Pressing the \"return\" Button will bring you back without loosing the code you entered.";
}
}
else
{
$usergen = fopen("web/" . $webname . ".html", "w") or die("Unable to open file!");
fwrite($usergen, $webcode);
fwrite($usergen, "<br><!--- ". md5($webpass) . " --->");
fclose($usergen);
echo "Generated! You can view your site under /web/" . $webname . ".html";
}
echo "<FORM><INPUT Type=\"button\" VALUE=\"Back\" onClick=\"history.go(-1);return true;\"></FORM>";
?>
What it does it pretty simple, you enter some html-code that'll be stored in the "webcode" variable, a password, let's say "apple" in "webpass" and the filename is stored in "webname".On first creation, a html-file is created with the <!--- md5(apple) ---> at it's end, the HTML Tags are needed to hide the string from any visitors. If someone wants to edit the File created before, he also enters "apple". Then the string will be looked up as md5(apple) in the file. If the strings match, it's true and the changes should be saved. Whatever i do, though, i'm allways ending up here if i try to edit an existing file: "The file already exists but you entered the wrong Password.<br> Pressing the \"return\" Button will bring you back without loosing the code you entered."; As i said, i'm a newbie, i'd appreciate any tips and help. Thank you in advance! Hello there people. I'm looking for the easiest & most solid way to append 1 or 2 strings to a certain PDF file. I have an application which a logged-in user will be able to print. When he prints it, his name and a counter string must be appended in a blank space in the application. So I don't need to replace a string in a PDF or something, just append. The PDF file will always be the same: the application to be filled. I've heard somewhere that you can do it easily with the Zend framework. I've also heard for some other libraries like TCPDF & FPDF. Any suggestions? Thanks Here's what I need to do: I have a page that reads file and simply echos it. $mystring = file_get_contents($file); echo "$mystring"; There is one piece of info I need to parse out and then use as part of my page title. The phrase I need to parse is an HTML comment field and looks like this: <!--PageTitle=<some text here> --> I'm sure this is simple but I'm clueless as you can tell. How can I do this? DryAquaman
In PHP Version 8.0 shows error as : In previous versions of PHP it does not show any error. Please resolve the issue. Hi, I am relatively new to PHP, and I am making a php script that will FTP into a server and add a donator's ID to a text file. However, I need it to check and see if the user is already listed under a usergroup in that file, and if so, remove those lines of text. Here's an example of what values in the file look like. Basically, I don't know how I could compare the contents of the file and delete it or replace parts of it when necessary Code: [Select] "STEAM_0:0:33358541" { "deny" { } "group" "moderator" "name" "TR Cpt. K. Reese" "allow" { } } Also, notice the "deny"{} and "allow"{} These are used for storing special commands that you allow or disallow the user to have in a game. How would i get a PHP script to ignore that... This uses STEAM's framework for userids. All help is appreciated!! Thanks! Hello, Okay for some reason i cannot do this, when i open a file in php and search for string, it doesn't seem to work, some codes i tried: Code: [Select] $filename = 'example.txt'; $searchfor = 'hello'; $fh = fopen($filename, 'r'); $olddata = fread($fh, filesize($filename)); if(strpos($olddata, $searchfor)) { //fount it } else { //can't find it } fclose($fh); (above it just sample text, i was hoping you could give me sample code that will work) I tried many others like strstr, stristr, preg_replace etc etc, doesn't seem to find it.. this is my text file: Code: [Select] sdfsdfsdfsdfsdf[b]hello[/b]sdvsdf dfadfsdfsdfsddfsdf sdfsdfsdfs sdffffffffffffffffffffdv vsvdsdsf I don't want to find it by line, i want to simply open the text file and find the string.. thanks.. This one stumped me, but maybe someone has figured it out. I'm trying to write a script that is able to decide whether a remote url is a directory or a file, this is fine until it comes to mod_rewrite(rewritten?) urls. ex. http://www.example.com/test Now this could be test.php,test.html etc., but in the rare case, it could also be a folder (example.com/test/index.php). Anyone have any ideas? Is it pasible to find all occurrences of strings "North" and "North-East" in some txt file and save number of occurrences in some variables?? I need to know if a string exists within a string. I've tried using STRIPOS() but it returns zero or false if what I'm looking for is the first part of the string. I don't care what function I use, but I need to get a "true" when the needle string is present anywhere in the haystack string, even at location zero. Is there some way to set up the STRIPOS() statement? I've tried: if ((stripos($title, 'needle') > 0 ) if ((stripos($title, 'needle') = true ) and even if ((stripos($title, 'needle') >= 0 ) which returns true for everything, even when the needle string is NOT present. Any help appreciated. thanks, Tom I am looking for a date within larger string, lets say the date is December 4, 2010. To find it I use pattern and function below: $Pattern='/[(January|February|March|April|May|June|July|August|September|October|November|December)] \d, \d\d\d\d/i'; preg_match_all($Pattern, $String, $Matches, PREG_OFFSET_CAPTURE, $NumberPosition); The function finds the dates within the string but to my supprise the result I get in $Matches is: r 4, 2010 What I would like to get is: December 4, 2010 but don't know how it should be fixed. I thought that with the pattern I am using but obviously that is not the case. |
