PHP - Strip Only Certain Tags, Remove Body Tags, But Keep Its Content.

This topic has been moved to PHP Regex.

http://www.phpfreaks.com/forums/index.php?topic=347065.0

Hi guys I need to be able to extract (into an array) the content between two tags "<!--" and "-->" in a string ($string).

I have       
$string = "<!--HELLO WORLD-->";
$tags = "/<!--(.*?)--!>/";
         preg_match($tags, $string, $matches);
         return $matches[1];

but it does not seem to work, (no error code, nothing).

Any help much appreciated,

I am asking out of curiosity, how does this problem usually get solved, when using a tag system to sort content, and users enter similar tags.

For example:

flower and flowers...

which means the difference between singular and plural. Judging by other sites which are around, this problem is not solved at all, they simply let you add as many tags as you want and then rank the most used tags, it indeed is a solution, but seems more like a walk-around solution to me.

Any ideas how somebody could approach to solve this one?

EDIT:

My suggestion would be an analysis function, which analyzes the entered tag and then suggests the user that similar tags have been already entered and perhaps he wants to choose one of those which have been already entered. This does work though with a high traffic websites what can happen is the following:

php and php5

You can end up with two similar tags which are both widely used though have different meanings to the user base.

This one could be solved by simply prohibiting similar tags with little additions or changes, and so to speak "forcing" the user to choose something which is already there. May be a way, though it can turn out as a bad solution as well.

Do anyone know how i can put the html tags in the same line as the other html tags?

Here's an example:

Code: [Select]
Images | Link | Delete | Enabled

On my code, it break the tags to the new line without put on the same line as the other tags.


Here's the code:

Code: [Select]
[code]<?php
session_start();
    define('DB_HOST', 'localhost');
    define('DB_USER', 'myusername');
    define('DB_PASSWORD', 'mypass');
    define('DB_DATABASE', 'mydbtable');

    $errmsg_arr = array();
    $errflag = false;

    $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
    if(!$link) {
  die('Failed to connect to server: ' . mysql_error());
    }

    $db = mysql_select_db(DB_DATABASE);
    if(!$db) {
  die("Unable to select database");
    }

   function clean($var){

return mysql_real_escape_string(strip_tags($var));
    }

    $username = clean($_GET['user']);
    $password = clean($_GET['pass']);
    if($username == '') {
  $errmsg_arr[] = 'username ID missing';
  $errflag = true;
    }
    if($password == '') {
  $errmsg_arr[] = 'PASSWORD ID missing';
  $errflag = true;
    }

    if($errflag) {
  $_SESSION['ERRMSG_ARR'] = $errmsg_arr;
  echo implode('<br />',$errmsg_arr);
   }
   else {
  $qry="SELECT * FROM members WHERE username='$username' AND passwd='$password'";
  $result=mysql_query($qry) or die('Error:<br />' . $qry . '<br />' . mysql_error());

if(mysql_num_rows($result) > 0) {
  $qrytable1="SELECT images, id, public FROM members WHERE username='$username'";
  $result1=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br />' . mysql_error());

  while ($row = mysql_fetch_array($result1)) {  
  echo '<p id="images"> <a href="images.php?id='.$row['id'].'">Images</a></td> | <a href="http://' .  $row["links"] . '">Link</a> </td> | <a href="delete.php?id='.$row['id'].'">Delete</a> </td> |  <p> <p id="test">'.$row['Public'].'</td>'';
  }
}
}
?>[/code]

Say I have the following text stored in a MySQL database...

Code: [Select]
<b>Classic Quote from movie</b>
and I retrieve it into a variable called $text, how do I properly echo that so that it keeps the bold tags and actually display the text "Classic quote from movie" in BOLD?

I'm doing something wrong somewhere along the line (simply doing "echo $text;") because it displays on the page as...

Code: [Select]
<b>Classic Quote from movie</b>

Instead of...

Classic Quote from movie

Any info on properly storing and echoing back HTML would be very appreciated.

I found this code on a website:

How would i edit this to look in a directory, and sub-directories and get information for every mp3 and add the data to a mysql database (the latter i can do easily)

Hi guys, i have not started this as of yet, however i will be given a project to make a micro-blogging website similar to that of Twitter or Facebook but obviously on a much smaller scale

I have been searching on google however i have not found anything. Maybe i haven't been using the right words in my query, not sure :-/

I have been trying to do some research, however i can't seem to find how to incorporate @ tags found in Twitter / Facebook.
e.g. If i want to tag a person in a Status Update:
Hey @John Smith, Football in the park at 3pm?

If anyone is able to help i would be grateful

Thank You   

alright I've seen and use
Code: [Select]
<?php Code: [Select]
<?but never before do I recall seeing
Code: [Select]
<?=
Nor do I even know where to look that up, so.. anyone ever see that used before, if so, any insight as to why someone would choose that?

How does PHP continuity exist in different php tags?
for example, if i connect to a database in a header,
and close the tag,
can I still work off of the same database in another tag?

<?php//NOTE ?>

With <?//NOTE?> Is all ok and it dosnt give me that error ..
could anyone please tell me why dos it give the error and some more details about the tags etc

Thanks in advance

I have just been given some code that is live on a web site. I pulled it down to my local linux machine and the php will not run. I have worked out the issue
the php tags are <? scripting ?> it is missing the php.

I have a couple of questions how do I get my local linux  machine get <? scripting ?>   this to work and I have a lot of code that is like this and I am sure
that it is no longer secure is this right?

I am working on a poject, where the search functions doesnt work as the user wishes. The coding is technically correct, but the idea behind it is wrong.

Basically at the moment, the script receives this:

thesite.com/search.php?q=xxxx&Submit=Search

The search script then runs a database query to search the tag coloumn, looking for like $q. This would work, however the structure of the coloumn is tag1, tag2, tag3, tag4.

So my resolutions is this so far:

I explode the $q variable, via the + (if you search more than one term "thesite.com/search.php?q=search+stuff&Submit=Search"

I then count the elements in the array and write the database function accordingly

Code: [Select]
$var = @$_GET['q'] ;
$trimmed = trim($var);

$searchpieces = explode("+", $trimmed);

$dbquery="";

$count = count($searchpieces);

for ($i = 0; $i < $count; $i++) {
if($i == 0){$dbquery.="tags = $searchpieces[$i]";}
elseif($i > 0){$dbquery.=" OR tags = $searchpieces[$i]";}
}

So my database query is

        $sql = "select * from gallery where $dbquery order by date DESC " . $limit;

so my question is this.. how to i eplode the tags database coloumn, so my datase query an look at each tag fro "tag1, tag2, tag3" as "tag1" "tag2" "tag3"

I am not even sure if this is possible, but its the system that is already in place.

The problem with the current system, is because the pictures have alot of tags and the database query is $like $q, it just shows all images in the database as the result

I wish to have all my products show in an XML for googles product search.
Also when I try to view this in internet explorer I get an error about quote marks (") being invalid.
Code: [Select]
<?
header('Content-Type: text/xml; charset=UTF-8');

include("includes/functions.php");
$connected = dbConnect();

// the DATE_FORMAT is to make the date RFCwhatsit compliant
$datetocheck = date("Y-m-d H:i:s");
$sql = "SELECT * FROM `products` ORDER BY `productTitle` ASC";
$resultset = mysql_query($sql);

//echo("<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ? >\n");
echo("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n");
?>

Hi Guys

Whats the easiest way to store tags in a database from a php form?

If I have a text field called tags, and each tag is comma seperated how do I process the data?

I have a table called tags, with 3 fields, tag_id, post_id and tag

Basically how would I basically turn this input:

a tag, b tag, c tag from a form field to
tag_id cat_id tag 1 dont worry about me, i can work this out! tag a 2 dont worry about me, i can work this out! tag b 3 dont worry about me, i can work this out! tag c
Many Thanks

HI,   I'm using; https://github.com/o.../PHP-Pagination   It works on my local test server, but on EC2, short tags are apparently not enabled by default.   The pagination is printing php:

<div class="pagination"><ul class="<?php= implode(' ', $classes) ?>">
<li class="<?php= implode(' ', $classes) ?>"><a href="<?php= ($href) ?>"><?php= ($previous) ?></a></li>
<li class="number active"><a data-pagenumber="<?php= ($current) ?>" href="#"><?php= ($current) ?></a></li>
<li class="number"><a data-pagenumber="<?php= ($current + $x + 1) ?>" href="<?php= ($href) ?>"><?php= ($current + $x + 1) ?></a></li>
<li class="number"><a data-pagenumber="<?php= ($current + $x + 1) ?>" href="<?php= ($href) ?>"><?php= ($current + $x + 1) ?></a></li>
<li class="<?php= implode(' ', $classes) ?>"><a href="<?php= ($href) ?>"><?php= ($next) ?></a></li>

I tried replacing <? with <?php to no avail. Not sure if the fact that one dependency is named "render.inc.php" instead of just ".php" which is causing the issue. Any ideas why apache is doing this? I'd rather not edit the .ini. Thanks..
