PHP - String - Get Text After @
Hi all just a bit like twitter i have a message system where when one recieves a mail i want there username to be like @user in blue but when sending a message the @user is in the message itself along with the actual message itsself, so i am trying to get the @ and everything after it so i can then change its color, can anyone help with this?
Similar TutorialsI have managed to get this to work but it seems like it is a very long and messy solution. I was wondering if anyone had an idea of how this can be done better. I am new to php and don't know a lot. It shows the text between the tags <h1> and </h1> from the content of a different file Basically I had to start the substr() from the fourth position so it would actually skip the "<h1>" being included, and because I started on the fourth postion I then had to finish four places back to skip the "</h1>" being included. Code: [Select] <?php $id = $_GET['id']; $homepage = file_get_contents("./".$id.".php"); $title = stristr($homepage,"<h1>"); $titlepos = strpos($homepage,"</h1>"); $endpos = $titlepos - 4; echo "Title " . substr($title,4,$endpos); ?> I have the following variable: $text = "javascript:openimage('http://images.icecat.biz/img/norm/high/5966342-254.jpg',850,850)" Now I want to put the string "http://images.icecat.biz/img/norm/high/5966342-254.jpg" into a variable called $url ( $url = "http://images.icecat.biz/img/norm/high/5966342-254.jpg" ) How do I do this? Hey, I need a simple bit of code to do the following: I am trying to strip out a username in a string. This string will distinguish the username because the string will contain a * right before the username. For example: $string = "blah blah *username blah blah blah" The username can only contain numbers and letters. no spaces. And from that string all I want is the username, for example: $string = username (which will vary of course) Hope this makes sense, made it as clear as I possibly could. Thanks ahead! I do want to validate a password input field to only allow numbers and letters without special character and spaces, and I also do want the same for the name input field. Since the old fashioned ways are deprecated. How would one approach to solve this issue the new way? I am trying to wrap a string with an anchor tag if it finds a match with a block of text. Here is an example text block: CONOCO 1'10x8 VC DF TP SGN||PRINCIPAL ILLUMINATION||ENG: CO3028TP_0VPR||DWG: CO200428||TO BE: DYED DIESEL (SPEC)|| The string I would want to wrap with a link would be "CO200428". The next problem is the drawings (what I'm searching the text for) has over 115,000 possibilities. The text blocks to search are over 1300. I have the drawing names stored in a simple mysql table...but doing a foreach takes forever...I imagine it will take even longer when looking in the text blocks... Is there a way to easily to do the anchor wrap? I don't know regex very well... Hi, I am trying to take a string from a database and replace everything within {} with code... similar to how posting in a forum works. so say I have "...Lorem ipsom {gallery:1} sit imet..." it will take that string (from a DB) and replace "{gallery:1}" with "<?php gallery('1'); ?>". How can this be done? Or is there keywords I can search on to find the answer? Thank you in advance. 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.. The table in the script has a set max-width. How can now a too long continuous text string as in "blaaaaaaaa", which also does not contain a space or dash, be broken, so the table does not become stretched to far? Which function is used for this?

I'm new in PHP so any response would be much appreciated .. thanks Hello, I am attempting to create a script where a user puts a text string into a form and clicking on submit. Then it adds that text string to a mysql database and gives the user a link back to it. Something like mysite.com/key.php?id=4 and when going to that link it will display the text string from the database but printed in an image. I wrote something up but I cannot get it to work. I may be a little in over my head. Any help is appreciated.
The way I coded this all to work is the user inputs the information into index.php which givekey.php inserts that into the database. I have not yet figure out how to do this in one single step. After that I wanted it to navigate directly to key.php which would display the key and the link to that page with the ?key=XX attribute. getkey.php
<?php
require_once 'dbinfo.php';
// database connection
$id = $_GET['id'];
// do some validation here to ensure id is safe
$link = mysql_connect($servername, $username, $password);
if (!$link) {
die('Could not connect: ' . mysql_error());
}
@mysql_select_db($database) or die( "Unable to select database");
$sql = "SELECT ukey FROM keycode WHERE id=$id";
$result = mysql_query("$sql");
$row = mysql_fetch_assoc($result);
mysql_close($link);
header("Content-type: image/png");
echo $row['ukey'];
?>

I have this but of php i have been trying relentlessly to get working.. for over a month.
<?php
$abs="one two three four words";
$mT = "testing for matching words";
$words=explode(' ', $abs);
//$sf=($words);
if (preg_match($words, $mT))
{
echo "the url $mT contains a Word";
}
else
{
echo "the url $mT does Not contain a Word";
echo "$words[4]";
}
?>
You see, I get a responce only using the last line "$words[4]", (obviously, because I am pointing it the Matching word, (ie: with [4]) Edited June 9, 2020 by x1705 better description.

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 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 $tag; ?> but this returns an unexpected T_STRING, expecting ',' or ';' Can anyone debug this? I may well be being really silly! Hey there, Thanks for taking the time to read my thread. My issue is that I can't think of a way to edit a XML file using PHP's XML functionality and then assign the edited contents to a string instead of saving the file. Because my issue is that I have to edit the XML file based upon a string brought from a remote location then give it back to that remote location using a string again, to be exact I am doing it via Linux command line utilizing SSH2. This is what I managed to complete on my own. function CheckIVMPConfig($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 } } } } This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=326004.0 |
