PHP - Function To Add <p> Tags

Hello all, I have some piece of code that is nested like this


$variable = 'This is a global argument';
function parentFunction($variable) {
function childFunction() {
echo 'Argument of the parent function is '.$GLOBALS['variable'];
}
childFunction();
}
parentFunction(5);


What I want to know is - Is there a way to access a variable from the parent function without passing arguments to the child function? (Something like how classes have parent::?). I don't want to use $GLOBALS because it might cause some variable collision, and I didn't want to pass arguments because incase I decide to change the arguments in the parent function I'd have to do it in the child function aswell. From my searching around in the Internet it seems like this is not possible, but if theres a slight chance that there might be something out there, i'm willing to give it a shot .

Thanks in advance

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?

Hello

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?

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?

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)

I need to call usort from a class function, and I'm puzzled about how to define the comparison function.

I've tried to define the comparison function in the same class, but I can't get usort to call it. I found one hint that it will work if I make the comparison function static, but I tried that, and it didn't work for me.

If I define the comparison function outside the class, it won't have access to object properties that it needs to operate.

The only solution I can think of is to define the comparison function outside the class and put the object properties it needs in globals. Is there a cleaner way to do this?

Question 1) Is the only and proper way to call a parent function "parent::function()"?  Are there other/better ways from within a child function?

Question 2) What are the deciding factors for when to make a function or attribute static?  How do you make that decision?  Assuming 5.3...

Thanks.

I have this function completely written in my class file that I am working on.  The point to this function is to be able to check the login of a user or administrator for either of the control panels associated with my site.

It will check the session intime as well as the page / module referenced.  Once it passes all those checks, it will check and ensure the emailaddress/password stored in the current session still holds true and the account is still active...  if the account is still active it will update the lastActivity as well as update all of the session variables with what is currently in the database.

What I am looking for is basically a look at the function, see if it looks good..  If there is any part to it that could create security holes for the site just off the login function itself...

Usage: $q->validUser($_SESSION['user'], $_mod);

<?php
 function validUser($sess, $p) {

if ($sess['inTime'] == '' && $p != 'login' && $p != 'logout') {
session_destroy();
$login = '0';
$_int = '';
return $login;
} else if ($sess['inTime'] < time()-3600 && $p != 'login') {
$sess['inTime'] = '';
session_destroy();
$this->check_login($sess, $p);
} else {
$this->user = $sess['emailAddress'];
$this->pass = $sess['password'];

$login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' 
   AND status = '1' LIMIT '1'");
if ($login = $this->sql_numrows($login) < 1) {
$sess['inTime'] == '';
session_destroy();
$login = '0';
} else {
// logged in, lets update the database for last_activity AND the session.

$this->sql_query("UDATE users SET lastActivity = '".now()."' WHERE
  emailAddress = '".$this->user."'");
$login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' 
       AND status = '1' LIMIT '1'");
$login = mysql_fetch_assoc($login);
foreach ($login as $key => $value)
{ 
$sess[$key] = $value;
}
$sess['inTime'] = time();
$login = '1';
}
return $login;
}
}

?>

That is the main function, sql_query and sql_numrows is:

<?php
function sql_query($query = "", $transaction = FALSE) {
unset($this->query_result);

if ($query != "") {
$this->num_queries++;
if ($transation == BEGIN_TRANSACTION && !$this->in_transation) {
$result = mysql_query("BEGIN", $this->db_connect_id);
if (!$result) {
return false;
}
$this->in_transaction = TRUE;
}

$this->query_result = mysql_query($query, $this->db_connect_id);
} else {
if ($transaction == END_TRANSACTION && $this->in_transaction ) {
$result = mysql_query("COMMIT", $this->db_connect_id);
}
}
if ($this->query_result) {
unset($this->row[$this->query_result]);
unset($this->rowset[$this->query_result]);

if ($transaction == END_TRANSACTION && $this->in_transaction ) {
$this->in_transaction = FALSE;
if (!mysql_query("COMMIT", $this->db_connect_id)) {
mysql_query("ROLLBACK", $this->db_connect_id);
return false;
}
}
return $this->query_result;
} else {
if ($this->in_transaction ) {
mysql_query("ROLLBACK", $this->db_connect_id);
$this->in_transaction = FALSE;
}
return false;
}
}

function sql_numrows($query_id = 0) {
if(!$query_id) {
$query_id = $this->query_result;
}
return ($query_id) ? mysql_num_rows($query_id) : false;
} ?>

Any insight that can help to benefit these functions would be appreciated.

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 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,

Hi all

This probarly looks really bad but im trying to replase tags that change. So far it only replaces the last tag and not well either. I will try to show you
Code: [Select]
function testfunc($value)
  {
       if ($value=='gallery'){$return .= "this gallery has worked = --$value--";}
       if ($value=='email'){$return .= "this email has worked = --$value--";}

    return $return;
  }

$test = "this is a test {%email%} message {%gallery%} rtfgdsfgdsfg";

$test = preg_replace("#(.*){%(.*?)%}(.*)#is",'$1' . testfunc('$2') . '$3', $test);

echo $test;

this outputs
this is a test {%email%} message rtfgdsfgdsfg

but im trying to get this
this is a test this email has worked = --email-- message this gallery has worked = --gallery-- rtfgdsfgdsfg

Im sure im way off but I hope you can understand. Thank you for taking the time to read this post.

I have a string $str that contains a web page information. it has multiple title tags [title][/title] within it. How do I get the contents within all these title tags

thanks
