PHP - Php Scrit To Compare A File With A String
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! Similar TutorialsBest method to for the following? Code: [Select] // The following $str1 and $str2 should say they are identical $str1 = "abcDEF"; $str2 = "EcFabD"; // The following $str1 and $str2 should say they are NOT identical because of the "a" "A" case difference. $str1 = "abcDEF"; $str2 = "EcFAbD"; I'm comparing bitvector strings. "ABC" is different than "abc". "abc" is the same as "cba". What's the best php function or method I should use? Thank you. Hi All, I'm working on PHP scripts to interact with a web hosted MySQL DB for an Android Application. Simply what I am trying to do is in the PHP script is run a SELECT statement which will return the value of a column, UserType, and compare the result of this to a string, which will then execute code depending on it's value. This user type can only be either 'student' or 'lecturer'. Any help with this would be much appreciated.
<?php
require "init.php";
$user = $_GET["userID"];
#Selects column account type where the idNum equals $user which is passed from my app.
$sql1 = "select accountType from user_info where idNum = '$user'";
$result1 = mysqli_query($con,$sql1);
$row1 = mysqli_fetch_assoc($result1);
#This is where I am stuck. Simply, I am trying to run the code in the loop where the result of $sql1 equals 'Student'. The else will run if it is not #student and therefore is 'Lecturer'. I'm also not sure if my code inside the IF is fully correct either as it's not running that far.
if($row1['accountType'] == 'Student')
{
$sql2 = "select courseCode from user_info where idNum = '$user'";
$result2 = mysqli_query($con,$sql2);
$row2 = mysqli_fetch_assoc($result2);
$sql3 = "select * from module_details where classListCourseCode = '".$row2['courseCode']."'";
$result3 = mysqli_query($con,$sql3);
$response = array();
while($row = mysqli_fetch_array($result3))
{
array_push($response,array("moduleID"=>$row[0],"lecturerID"=>$row[1],"moduleName"=>$row[2],"classListCourseCode"=>$row[3]));
}
echo json_encode(array("server_response"=>$response));
}
Thanks in advance. I want to perform a query which returns a subset of the fields in a table. One particular mySQL field is VARCHAR I have a query like this: $query = mysql_query("SELECT * FROM table WHERE code LIKE '3%') ; It's my understanding this should return all values which begin with "3", but it only returns about a dozen of the values 3, 30-39, 300-399, etc. (It works with string fields, but this field contains numerals.) Any help appreciated. thanks, Tom Hi everyone. Well, i need help how to check a file line by line, (each line contains 1 ip address) and compare it with a variable. I have written some code but it doesn't work. Please help!! Code: [Select] $refile=''; while(!feof($file)) { $refile=fgets($file); if (strcmp($refile,"YES") == 0) echo $refile ."OK". "<br />"; else echo $refile . "NO OK ". "<br />"; } fclose($file); ?> 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 } } } } 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 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 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?? Currently I am using a script that displays the entire directory. However I am trying to use preg_match to try and figure out
how to just link to one file from the directory via a search string from a form.
I am probably not even close so please bare with me
<?php
if (isset($_POST['filelook'])) {
$filez = $_POST['filelook'];
}
/*
edit $path to the directory you want to use
edit $file_types to change the file types to show
*/
function file_type($file)
{
$searchString = $filez;
$path_chunks = explode("/", $file);
$thefile = $path_chunks[count($path_chunks) - 1];
$dotpos = strrpos($thefile, ".");
return strtolower(substr($thefile, $dotpos + 1));
}
$file_count = 0;
$path = "./WinFiles/files";
$file_types = array('png', 'jpg');
$p = opendir($path);
while (false !== ($filelook = readdir($p)))
{
$files[] = $filelook;
}
sort($files);
echo "<b> Your file results:</b><br> ";
if (file_exists($filez) && is_readable($filez) && preg_match($filez)) {
echo '<a href="download.php?f='.$filez.'">'.$filez.'</a> <br/>';
//find filename like name searched for...
if($file_count == 0)
{
echo "<b>No file match your file types</b>";
}
}
?>
Hi to everyone. So, I have a little php code that reads line by line from a txt file, specifically i have 1 IP address for each line, and compares it with the current user's IP. It's like a little blacklist code. But it doesn't work. Can anyone see what i am doing wrong? Code: [Select] $file = fopen("ipblacklist.txt", "r") or exit("Unable to open file!"); //Output a line of the file until the end is reached $ipblacklist=''; $refile=''; while(!feof($file)) { if (fgets($file)== $_SERVER['REMOTE_ADDR']) $ipblacklist='error'; $refile=fgets($file); } fclose($file); Thank you in advance Hello, We've been working on a page that allows users to create their own avatar to be displayed on their page.

INSERT INTO `subjects` VALUES (1, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (2, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (3, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (4, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (5, 'some text here', 'some text here', 'some text here'); I wanted to replace the string " VALUES (1, " with "VALUES (" in each line .. I'm new in PHP so any response would be much appreciated .. thanks $poststart = "<!-- Begin -->";
$poststop = "<!-- End -->";
$parsedpost1 = explode($poststart, $contenu);
$parsedpost2 = explode($poststop, $parsedpost1[1]);
$contenu = $parsedpost1[0] . $poststart . $newpost . $poststop . $parsedpost2[1];
The above code will set 2 markers and replace whatever inside by $newpost, which is defined elsewhere in the page. But what if $newpost is so long that I'd be more comfortable storing it in a separate file?
How would I go about calling said file on that last line? (I'm referring to the specific syntax.)
Thx
Hi, I want to compare the tables from 2 mysql databases in a table. This is what I have: for($i=0;$i<$maxCount;$i++) { echo "<tr>"; // start row //fist data square if ($i < count($db1)) echo "<td>{$db1[$i]}</td>"; else echo "<td></td>"; echo "<td></td>"; // middle //last if ($i < count($db2)) echo "<td>{$db2[$i]}</td>"; else echo "<td></td>"; echo "</tr>"; // end row } that will put make a nice table for me to see. What I'd like to do next is have all identical sql tables lined up. So for e.g I have 2 arrays of table names that will look like this: Databse 1 Database 2 table1 table1 table2 table3 table4 table4 does that make sense? Also is there a more elegant way of scripting what I have? Can php be used to get two blog entries and compare them side by side, with a choice one which one to use. A bit like wikipedia has ? I thought I was able to determine which DateInterval is greater the same as done with DateTime, however, either this is not true or I am doing something wrong. Please advise. Thanks!
private function compareDateInterval(\DateInterval $dateInterval1, \DateInterval $dateInterval2):bool
{
$greaterThan = $dateInterval1 > $dateInterval2?'true':'false';
echo("test1: dateInterval1 > dateInterval2: $greaterThan\n");
$dateTimeNow = new \DateTimeImmutable;
$dateTime1 = $dateTimeNow->add($dateInterval1);
$dateTime2 = $dateTimeNow->add($dateInterval2);
$greaterThan = $dateTime1 > $dateTime2?'true':'false';
echo("test2: dateTime1 > dateTime2: $greaterThan\n");
$timestampNow = $dateTimeNow->getTimestamp();
$timestamp1 = $dateTime1->getTimestamp();
$timestamp2 = $dateTime2->getTimestamp();
$greaterThan = $timestamp1 > $timestamp2?'true':'false';
echo("test3: timestamp1 > timestamp2: $greaterThan\n");
echo('$dateTimeNow => '.json_encode($dateTimeNow).PHP_EOL);
echo('$dateInterval1 => '.json_encode($dateInterval1).PHP_EOL);
echo('$dateInterval2 => '.json_encode($dateInterval2).PHP_EOL);
echo("timestampNow: $timestampNow, timestamp1: $timestamp1, timestamp2: $timestamp2\n");
}

Hi everyone! I've been looking for a solution, but i just can't find it anywhere... Ok, so the problem is: i have a database which looks something like this: user_id product_id score 14 . 235 . 79 23 . 235 . 32 53 . 665 . 21 14 . 235 . 90 5 . 675 . 45 This is step-by-step of what i need to do: 1. Select user - user_id =343 2. For user_id =343 select all products that he gave score to: product_id = 43 - score = 99 product_id = 12 - score = 56 product_id = 68 - score = 32 product_id = 124 - score = 67 3. Find all users that voted for the same products e.g.: for product_id = 43: user_id = 125 voted 93 points, user_id = 23 voted 56 points. 4. Calculate the difference between the score of user, so: for product_id = 43: user_id = 125 voted 93 points (99 - 93 =6 points of diff.) user_id = 23 voted 56 points (99 - 56 =43 points of diff.) return the results.... That's basically what i need to do. I still don't know the number of the users, or product, but it doesn't really matter - i just need to make it work. Ok, hope someone can help! |
