PHP - Can't Find Answer Cause I Don't Know What Its Called :) Lol

i saw this in a php function page he

http://php.net/manual/en/function.stristr.php

the line is
 if(stristr($string, 'earth') === FALSE) {

specifically this this code
<?php
  $string = 'Hello World!';
  if(stristr($string, 'earth') === FALSE) {
    echo '"earth" not found in string';
  }
// outputs: "earth" not found in string
?>


what is the significance of the '===' in there
does it mean something? is there any difference from the '==' or the '=' ?

<?php

I just finished a page of code that passes all the debug tests except for the very last line on the page. </html>. The page has php and html, java script and some SQL. (see I'm learning and hadn't placed a post until I exhausted my limited resources.

The Error Codeis:
PHP Parse error: syntax error, unexpected $end in C:\wamp\www\registerform.php on line 292

Here's my concern:

I read this error statement as an error()is missing. Please clarify something for me, You start the php code with <?php and end it with ?>.

 I also understand that the end() will stop all further operation. Correct. When you have a form call itself  for data checking,   and if the data is correct, send it to the appropriate database table, does one need to place the end() at the end of the php portion of the code? And if so, will it not stop any of the code from being read the first time the page is called?

Also since the FORMs action calls for the page to load itself for data verification, how at the end of the checking do I go call another page?
here's the page:

The page is attached:

It's a little difficult for me to explain but, when a website loads another site (For example with Curl or something) How is the site able to keep a header or some part of original site 'attached' to the site they loaded..for example, say you're redirected, the site you redirected to loads, but you still see the site you redirected from header on at the top of the page. How is this done? What is it called? Do you need me to clear it up a bit better? I can try to find an example.

I've been trying to find tutorials/coding today related to controlling the ability to download files. The problem I think I'm having because I know it exists is I don't actually know what it's called. Below is kind of a basis for a tutorial or describing what I'm trying to do.


I'm trying to find a tutorial or a how to on storing downloadable files either in a Mysql Database &/or on the file server system. I want to make it so that only users that are stored within the user database who have certain rights or a field can be able to download a file. Those users who don't have the proper permissions in the user table will not be able to and those who do when they go to download a file, will be able to. I know these scripts use PHP but am not really sure where to begin on my search because I don't even know what file permissions coding they are using.

I have a function that creates a dropdown list in a form.  The User saves their answer to the mysql table.  How do I get their preselected answer back out of the table when they visit the form again?
I know how to pull it from mysql and into a variable, but how to modify the below code to display the correct answer stumps me.

Here is my dropdown function:
Code: [Select]
function dropdown($array, $id) {
  echo '<select name="'.$id.'" id="'.$id.'" class="select"><option value="">Select one...</option>';
  foreach($array as $key => $value) {
  echo '<option value="'.$value.'">'.$value.'</option>';
  }
  echo '</select>';
  }

Thanks for the help!

Hello PHP Freaks forum,

I am a beginner in web development and seem to be understanding it very quickly, but there is one thing that is putting this into some halt.

I have this code right here, what I want to do is have a "riddle site", where if you answer the riddle correctly, it redirects you to another page (in other words to the next riddle).

Object:
If correct, give access to next page.
If incorrect, stay on page and print "Incorrect".

I've tried to start on it, but the way how HTML and PHP don't mix very well, I feel like in the middle of an ocean feeling helpless.

</form>

 <?php
if(isset($_POST['submit'])){

$number = $_POST['number'];
if ($number == "scuba"){
echo "CORRECT";}
}
?>

</html>


If possible, can you give me an explanation how to do it and a sample of it as well?

Thanks,

Hey guys, I am still kinda new to php and I can't seem to get this to work.  Basically I am calling a script and first I need it retrieve certain values which is working fine, but then after that is called I need it to clear those values it just displayed.  To do that I am using UPDATE but it doesn't seem to be calling the UPDATE part.  Any ideas?  Here is the code:

Code: [Select]
@mysql_select_db("$db_name") or die ("No DataBase Found");
$result = mysql_query("SELECT * FROM members WHERE id='$_POST[id]'");
while ($row = mysql_fetch_array($result))
{
$message = $row['message'];
$sender = $row['sender'];

echo $message . "\n" . $sender;
}

mysql_query("UPDATE memebers SET message='' WHERE id='$_POST[id]'"); //These never get
mysql_query("UPDATE memebers SET sender='' WHERE id='$_POST[id]'");//called or so it seems

Hi guys, What is it called when you have a long paragraph shoretend, With php of course, To make it like haljh;lajbsdg...

For example, I have this paragraph:

Code: [Select]
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus placerat consequat enim, pretium viverra massa cursus nec. Sed in pharetra magna. Aliquam egestas vehicula mi, sed pellentesque ligula suscipit a. Donec lectus velit, luctus sed lobortis vitae, sollicitudin in sem. Ut facilisis, velit in accumsan porttitor, libero neque molestie leo, ac vulputate eros libero eget mauris. Ut nec justo augue.
How to I make it so PHP detects if it is too long and trims it down like:

Code: [Select]
Lorem ipsum dolor sit amet, consectetur adipiscing elit...
If I can find what this is called then I can google it to find it and use it on my site.

Thanks in advance!

hi,

i just wanted to know...

$arr[0] $arr[1] $arr[2] also this $arr[1] would be called a value, but how are the numbers 0,1 and 2 called? are that keys?

didn't know where else to post this question.

Here's some of my code.  The fault is when AJAX sends the dataString to sendpm.php, it should call the function.  But nothing is happening.  If i put the sendprivatemessage query in sendpm.php page, the data is sent to mysql.  What is the solution, so i don't have to put the query on sendpm.php?

jquery - some of it
Code: [Select]
$.ajax({
type: "POST",
url: "/sendpm.php",
data: dataString,
success: function() {
window.location.href = 'http://www.stackway.com/cp/messages=outbox';
}

});
sendpm.php
Code: [Select]
include "database.php";

$to = $_POST['to'];
$from = $_POST['from'];
$subject = $_POST['subject'];
$body = $_POST['body'];

$database2 = new Database();
$database2->opendb();
$database2->sendprivatemessage($to,$from,$subject,$body);
$database2->closedb();

sendprivatemessage function
Code: [Select]
function sendprivatemessage($to,$from,$subject,$body) {

$insert = mysql_query("INSERT INTO privatemessage VALUES ('','$subject','$body','$to','$from','1',NOW(),'','','')",$this-connect);

}

I have 2 forms on a page, 1 with a selection of newly registered accounts and another that displays the information on the user. What I need to happen is when a user is selected from the first form, the second form is populated with the data. I'm trying to do this with a combination of php and javascript, however whenever a user is selected the function isn't being called at all as far as I can tell. Can anyone help me get this working please?

I apologise if I've butchered the code, I'm still learning.

I need to make my client's site distinguish among different tabs in the same browser. (See http://www.phpfreaks.com/forums/index.php?topic=357772.0 for background.)

I create a tab ID when the user first visits the site in a particular tab, and I'm passing it from page to page as a parameter. This seems to be the only way to do what I need.

The tab ID is always passed through POST so that the user won't see it. If it were visible, users could make trouble (or more likely get in trouble) by adding or removing the ID themselves.

This is not simple where a page is loaded by a hyperlink. The anchor tag passes parameters via GET, period.

The solution I found is to link to a script named post.php, which takes the real link target and the tab ID as parameters, sends the browser a form that passes the tab ID to the real link target via POST, and auto-submits the form via JavaScript.

This works, but it requires two round trips to the browser to load a page. It's also a pain to code.

Is there a more efficient way to do this... perhaps a way to make the server send the browser a POST response, even though it made a GET request?

If it matters, the server is Apache 2.x.
