PHP - Do Die Statements And Echos Display Differently?

How come my$_SERVER['PHP_SELF'] echos the filename.php

I have a rewrite rule and i need it to echo

http://site.com/file/321

instead of filename.php?id=321


Help! Godaddy wont tell me why its doing that

Hey guys it's been a long time, but I am back with php!

Anyway here's my dilemma:

test.php

<?php
<?php
$name = array('Chris', 'Bob', 'Jack');

$names = print_r($name);
?>


Simple enough right? Well although I am not printing/echoing these results to screen it does it automatically.

Meaning when I point my browser to test.php it outputs this:
Code: [Select]
Array ( [0] => Chris [1] => Bob [2] => Jack )
Rather than only assigning the value to the $names variable, which is what I would expect it to do. Is this normal behaviour or is there something I can change on php.ini?

Thank you!

While testing...

php seems to be changing the & symbol into a square bracket when retrieving from $_GET. I assume this is so it can still use the & to seperate variables placed into the URL.

When i print_r the $_GET i get this:
[name] => [lt;table]

My question is... is there a function which decodes this?

For example, the name, "&lt;table&gt;" is actually stored in my table due to html entities as you see therefore if the name is ever passed via the URL, the & messes it all up.


Furthermore, are there any other characters like this i should be looking out for?

I've been doing some benchmarking for memory usage for a very resource-sensitive project I'm doing (that I probably shouldn't be using PHP for, but oh well). I came across something peculiar, and I'm trying to figure out why I get results as I do.

Here is my test file:

<?php
$string_parts = 4;
$max = 10000;
$arr = array();
$i = 0;
$start = memory_get_usage();
for(;$i<$max;$i++){
$arr[] = array_pad(array(), 4, "A");
}
$end = memory_get_usage();
printf("%d iterations, %d bytes in array\n", $max, $end-$start);

$arr2 = array();
$i = 0;
$start2 = memory_get_usage();
for(;$i<$max;$i++){
$arr2[] = array("A", "A", "A", "A");
}
$end2 = memory_get_usage();
printf("%d iterations, %d bytes in array (%.2f%%)\n", $max, $end2-$start2, ($end2-$start2)/($end-$start)*100);
?>


Output on my system:
Code: [Select]
10000 iterations, 4145696 bytes in array
10000 iterations, 5585744 bytes in array (134.74%)
A 35% memory gain for two of the same exact arrays seems really weird. Any information as to why, or perhaps any useful functions or resources would be appreciated.

but never on the first call.  Okay, I posted this on StackOverflow but no one there seems to have an answer either.  I have this simple function:

Code: [Select]
public function delete($messageID) {
$type = $this->findType($messageID);
if ($type == 'in') {
foreach ($this->inArr as $key => $value) {
if ($this->inArr[$key]->messageID != $messageID)
$implodeData[$key] = $this->inArr[$key]->messageID;
}
if (!isset($implodeData))
$imploded = '0';
else
$imploded = implode(',', $implodeData);
$result = $this->_database->updatePMUser('inArr', $imploded, 'UID', $this->UID);
$result2 = $this->_database->deletePM('messageID', $messageID);
return;
}
else {
foreach ($this->sentArr as $key => $value) {
if ($this->sentArr[$key]->messageID != $messageID)
$implodeData[$key] = $this->sentArr[$key]->messageID;
}
if (!isset($implodeData))
$imploded = '0';
else
$imploded = implode(',', $implodeData);
$result = $this->_database->updatePMUser('sentArr', $imploded, 'UID', $this->UID);
$result2 = $this->_database->deletePM('messageID', $messageID);
return;
}
}
It is a delete function for a private messaging program for a forum script I'm writing.  Anyway, here's the issue - it works!  But only sometimes.  It is called in 3 different places, always from a form processing class I have, once in the view message section to delete a message you're viewing, in a foreach from the sentbox options section and then a foreach in the inbox options section.  The inbox and sentbox option sections do that whole "delete the checked messages" for the mass removal functionality.  The delete function above works in all ways shapes and forms when I use it in single calls - like when I'm deleting a message while viewing it or when I only check one message from the inbox, etc - but when I call it multiple times (as in I have checked multiple messages) - it fully deletes one (both the message and the reference to the message in the user's db row) and then only deletes the actual message on the others (deleting the message is the call to deletePM - deleting the reference is the call to updatePMUser).

Okay, if you need further information - the function above checks the type the message is (in the inbox or in the sentbox) and then uses that to foreach through that array (inArr or sentArr) of the user.  It logs in all the messageIDs of the those that DON'T match the one we're deleting and then at the end it implodes those caught IDs into a string that is then updated in the user's row as a comma separated string of values each representing a message in the DB - you get the picture.  I realize I have some trimming to do (for one I can cut the above function down by about half by using variable variables) but I'll get to that after I get the thing working.  I can't figure out why it's doing what it's doing.  If you need the function that calls this in the foreach, I have it below.  Oh, and the thing that really boggles me is that this function is called fully for each checked message in the foreach - it fully returns and then loops - if it works once, I don't see how it wouldn't work on a second call from a loop - the variables it uses should be trashed when it leaves the function, they aren't global or object properties or anything.  Color me confused.

Thanks for any help, oh, here's one of the functions that calls it to delete checked messages (this one is for the sentbox, there is another for the inbox):

Code: [Select]
private function _processSelectedSent() {
$pmObj = unserialize(base64_decode($_POST['pmObj']));
$i=1;
foreach ($_POST as $key => $value) {
if ($value == 'marked') {
$checkedArray[$i] = $key;
$i++;
}
}
if ($_POST['submitter'] == 'Delete Selected') {
if (is_array($checkedArray)) {
foreach ($checkedArray as $key => $value)
$pmObj->delete($value);
}
else
$pmObj->delete($checkedArray[1]);
header("Location: ".HOME_PAGE.PM_PAGE."?view=sentbox&nocache=".time());
}
}

Hi guys,
I'm trying to write a script that generates a multipart plaintext/HTML email with a pdf attachment. After much research and trial & error, I seem to have reached a wall.
 
At the moment, I am testing in gmail, hotmail and Outlook 2003. Gmail displays the HTML alternative of the message and attaches the pdf document, while hotmail & Outlook only attach the pdf without displaying either of the message alternatives.
 
Here is the code:
 // Error display
  ini_set ('display_errors', 1);
  error_reporting (E_ALL | E_STRICT);
 
 // Setting a timestamp
  date_default_timezone_set('Australia/Perth');
  $timestamp = date("d/m/y H:i:s", time());
  
  // Create a boundary string. It must be unique, so we use the MD5 algorithm to generate a random hash 
  $random_hash = md5(time()); 
  
  // Read the attachment file contents into a string, encode it with MIME base64 & split it into smaller chunks
  $attachment = chunk_split(base64_encode(file_get_contents("success.pdf")));
  
  // Create the Plain text message to be sent in the email body
  $content_text = "Hello, World!! \nIs this a Plain Text alternative?";
  
  // Create the HTML message to be sent in the email body
  $content_html = "<html><body><h1>Hello, World!!</h1><p>This is <b>HTML</b> formatting.</p></body></html>";
  
  // Sending the email
  $to = "$email";
  $subject = "Test5-3.php :: $timestamp"; 
  
  $headers = "From: The Company <webmaster@example.com>\n";
  $headers .= "MIME-Version: 1.0\n";
  $headers .= "Content-Type: multipart/mixed; boundary=\"$random_hash\"\n";
  $headers .= "--$random_hash\n";
  $headers .= "Content-Type: application/pdf\n";
  $headers .= "Content-Transfer-Encoding: base64\n";
  $headers .= "Content-Disposition: attachment; filename=\"success.pdf\"\n\n";
  $headers .= "$attachment\n";
  
  $message = "Content-Type: multipart/alternative; boundary=\"$random_hash\"\n";
  $message .= "Content-Type: text/plain; charset=\"iso-8859-1\"\n"; 
  $message .= "Content-Transfer-Encoding: 7bit\n"; 
  $message .= "$content_text\n";
  $message .= "--$random_hash\n";
  $message .= "Content-Type: text/html; charset=\"iso-8859-1\"\n"; 
  $message .= "Content-Transfer-Encoding: 7bit\n"; 
  $message .= "$content_html\n";
  $message .= "--$random_hash--";
  
  // Send the data in an email
  $mail_sent = @mail ($to, $subject, $message, $headers, "[email]-froot@clarebyrnedesign.com.au[/email]");

 
(That's not the full script, but it is the relevant part of it. The full script is attached.)
 
Other variations of this code I have tried out include:
     - surrounding all the variables with ". .", eg:   $headers .= "--".$random_hash."\n";
     - sending the entire function as headers, instead of splitting it into message and headers, eg:   $headers = "From: The Company <webmaster@example.com>\n";
  $headers .= "MIME-Version: 1.0\n";
  $headers .= "Content-Type: multipart/mixed; boundary=\"$random_hash\"\n";
  $headers .= "--$random_hash\n";
  $headers .= "Content-Type: application/pdf\n";
  $headers .= "Content-Transfer-Encoding: base64\n";
  $headers .= "Content-Disposition: attachment; filename=\"success.pdf\"\n\n";
  $headers .= "$attachment\n";
  $headers .= "Content-Type: multipart/alternative; boundary=\"$random_hash\"\n";
  $headers .= "Content-Type: text/plain; charset=\"iso-8859-1\"\n"; 
  $headers .= "Content-Transfer-Encoding: 7bit\n"; 
  $headers .= "$content_text\n";
  $headers .= "--$random_hash\n";
  $headers .= "Content-Type: text/html; charset=\"iso-8859-1\"\n"; 
  $headers .= "Content-Transfer-Encoding: 7bit\n"; 
  $headers .= "$content_html\n";
  $headers .= "--$random_hash--";
 
Does anyone know why I would be having this problem? It seems that nothing I've tried will work!!
 
Thanks

I am trying to write an if statement that checks to make sure the information put in the text box is an imbedded file. Does anyone know how to do that?

Hey Guys,

I am creating an array and I have a need to put a if statement inside it. Is this even possible?

Here is where I am at so far, its just not working.


 function load_permissions($gid)
    {
     $data = array();
     $this->db->select('`groups`.`name` AS `permission_name`, `permissions`.``');
$query = $this->db->get('`groups`,`permissions`');
if ($query->num_rows() > 0){
foreach ($query->result_array() as $row){
  $data[] = array(
  "name" => $row['permission_name'],
  "read" => if($row['level'] >= 1)
   { 
    img("img/true.gif")
   } else { 
    img("img/false.gif")
   },
 
  );
  }
 }
 
 $query->free_result();
return $data;



Thanks,
Peter

Anything wrong with this because I got a parse error ONLY after adding to create this.

<?php
                            $visible = array('Yes', 'No');
                            foreach($visible as $visible):
                            $visible2 = array('yes', 'no');
                            foreach($visible2 as $visible2):
                        ?>      

Hey guys,

is there any way to have a LIKE condition on an IF statement?
Something like:
Code: [Select]
if $GET_['WTV'] LIKE %LOVE% {
$category=romance
Any clues?
Thanks in advance.

The below is constantly loading the password page no matter what is enter in the password input on the form (on another page). I have checked the $login variable by echoing it and it is carrying the value from the field.


<?php
$off="yes";
$login=$_POST['login'];
if($off=="yes" && (!isset($_SESSION['login']) || $_SESSION['login']!="pass")){
    if($login=="" || $_SESSION['login']!="pass"){
    header('Location: ./index2.html');
    exit();
    }
    elseif(!isset($_SESSION['login'])){
    session_start();
    $_SESSION['login']=$login;
    header('Location: ./index.php');
    exit();
    }
}
elseif($off=="no" || $_SESSION['login']=="pass"){
content goes here.
}
?> 

Hi Guys,
Newbie trying to understand PHP conditionals.
In the below Code: [Select]
[[*id]] is a global variable which equates to my current page id so it could have the value of 1 for example. I tested it using echo and the correct values pass to it in the cms I'm using. What I cant achieve is for the conditionals below to work correctly so perhaps you can see a syntax error or show me away of doing the same using an array or something perhaps? THANKS

Code: [Select]
<?php
$id='[[*id]]'

if ($id=="1" || $id=="2")
  echo "we are in 1 or 2";
elseif ($id=="3" || $id=="4")
  echo "we are in 3 or 4";
else
  echo "not in 1 to 4";
?>

How to write 2 "if" statements together?

if($userResult==$myResult) and ($userResult<0)

Hello, I am learning PDO SQL statements, I have mananged to connect using PDO:


Code: [Select]
try
{
$this->link = $dbh = new PDO('mysql:host='.$this->dbhost.';dbname='.$this->dbname.'', $this->dbuser, $this->dbpass);
}
catch (PDOException $e)
{
echo 'Connection failed: ' . $e->getMessage();
}


I am not getting any error, so I guess that is a good start. I then tried the PDO SQL statement out. My old mySQL query is commented out in the


Code: [Select]
if (isset($_SESSION['id']) && isset($_SESSION['password']))
{
$_SESSION['id'] = ( isset( $_SESSION['id'] ) ) ? $_SESSION['id'] : FALSE;
$_SESSION['password'] = ( isset( $_SESSION['password'] ) ) ? $_SESSION['password'] : FALSE;


//$logged = mysql_query("SELECT * FROM `db_members` WHERE `id`='".$_SESSION['id']."' AND `password` = '".$_SESSION['password']."'");
//$logged = mysql_fetch_array( $logged );

// the new pdo statement
$ff = $dbh->prepare('SELECT * FROM db_members WHERE id = '.$_SESSION['id'].' AND password = '.$_SESSION['password'].'');

$ff->execute();
$logged = $ff->fetchAll();

echo $logged['username'];
}

I am trying to assign the session to logged variable. So all I am asking is go into db_members and check the id and password that is the same as session id and password and collect the rows data such as username.

My login script and everything works perfectly, even session id and password is valid when echo'd but I cannot assign it to the logged variable like my old sql statements.


Code: [Select]
$logged = mysql_query("SELECT * FROM `db_members` WHERE `id`='".$_SESSION['id']."' AND `password` = '".$_SESSION['password']."'");
$logged = mysql_fetch_array( $logged );

I used other PDO statements and it works perfectly but I just don't understand why this is not working.... can I please get some help if you have any solution to this?
