Re: [PHP] Efficiency question
For something like that that, unless you are doing it inside a loop, I

[PHP] Big files management
Hi there, I'm trying to deal with big files (over 4GB) with PHP4.3.9 ans PHP4.4 but obviously it's not really possible. Is there a library somewhere that allows elementary operations on these kinds of files by, for example, using the operating systems commands (Linux in this case)? Or any other solution?

both examples are just boilerplate 'frontcontroller' code that do pretty much
nothing
of themselves.
- in terms of speed you will notice nothing. in principle OO code is a little
slower
because creating objects has quite a lot of overhead as compared to just calling
functions (if your just creating 1 or 2 objects it's not measurable) - but then
it all depends on what the code inside object/function actually does!
An example:
switch($action) {
case 'edit':
//do some stuff
...
return edit_tpl.php;
case 'whatever':
//blah
..
..
}
OR:
$method=$this-convertToMethod($action);
my guess is that there will be a switch statement in convertToMethod()
to 'convert' $action into $method. so it effectively does what you example
switch()
is doing.
ask yourself whether you prefer to hide some of the complexity of what your
scripts are doing inside the bowels of an object - or whether you prefer to
use procedural code. either is fine, it's up to you - just make sure you write
neat,
well-documented properly thoughtout code and even the guy that has to
maintain your
stuff 2 years from now will be happy regardless of the paradigm you chose.
unset($action);
return $this-$method();
Hope this is reasonably clear... Note the return on the latter code.
If anyone has any ideas around this, please let me know! Are there
underlying security risks in doing it this way?
$action is coming from the client (eg. a GET/POST variable) - sanitize it!
validate it! use 'whitelisting' to trigger a reaction (rather than using the
actual value). don't trust data coming from outside your script/server (don't
trust
that either ;-).

[PHP] problem using
Hi
I am reading a username and password from a file. For the moment I am trying to
test if the username and password are the same as user inputted
username/password.
My code snippet is as follows:
if( $out[0][0] == $u $out[0][1] == $p ) {
$error = Login successful!;
}
else {
$error = Invalid username/password. Try again;
}
$out[] is an array containing the file data.
$u is the form username and $p the password.
I echo both values once submitted. Even when they match I get invalid
username/password message.
If I just test if( $out[0][1] == $u ) it works.
Has anyone any pointers on what I am doing wrong?
Thanks

you are testing it against $p which I guess is password..

Sorry, that was a typo.
I'm sure it was; and I'm sure that you have lots of typos.
here is test code that proves that if what you say it true regarding
the contents/structure of $out, $u and $p then when the relevant values match
you
will get the Login Successful! message; seeing as you are not it means you
are testing the wrong variables or something:
// CODE
$out = array(array(user,pwd)); $u = user; $p = pwd;
if($out[0][0] == $u $out[0][1] == $p) {
echo Match\n;
} else {
echo No Match!;
}
// OUTPUT
//Match!
$out[0][1] is the password. Should have read:
if( $out[0][1] == $p )
So that works, once i add the $out[0][0] == $u
it no longer works, even though my echo shows both values are the same...
do you know the difference between print_r(), var_dump() and echo?
try:
var_dump($out, $u, $p, ( user == user));

If I remember correctly, htmlspecialchars does what its name indicate: konvert any character with special meaning according to the HTML specification. htmlentities converts any character to its HTML representation.

RE: [PHP] jpg to pdf using fpdf
Check the FPDF function in the manual http://www.fpdf.org/en/doc/fpdf.htm, I
think you can set custom size of the PDF. You have to figure out how to get
the image size first, hint: getImageSize();), and then convert it to the
units you use for the pdf.

Hi Angelo,
So the first question the list will ask is if the array of data is
coming from a database. Because then you'd be urged to perform the
sorting from within your database query.
Barring that, you can use the usort() function to create custom
sorting. What I've done below should do what you want, and I've tried
to generalize the functions a bit, so that you can mix descending and
ascending as you wish:
[code]
// Basic function for comparing arrays based on a particular column
function compareColumn($x, $y, $idx, $lessThan, $greaterThan)
{
if ( $x[$idx] == $y[$idx] )
return 0;
else if ( $x[$idx] $y[$idx] )
return $lessThan;
else
return $greaterThan;
}
// Calls compareColumn so that it sorts in descending order
function compareColumnDesc($x, $y, $idx)
{
return compareColumn($x, $y, $idx, 1, -1);
}
// Calls compareColumn so that it sorts in ascending order
function compareColumnAsc($x, $y, $idx)
{
return compareColumn($x, $y, $idx, -1, 1);
}
// Your customer comparison function. The order in which you call each
// compareColumn*() is the ultimate order in which your multi-dim
array is sorted.
function compare($x, $y)
{
// total is index 2 of the array
$total = compareColumnDesc($x, $y, 2);
if($total != 0) return $total;
// totalPaid is index 3 of the array
$totalPaid = compareColumnDesc($x, $y, 3);
if($totalPaid != 0) return $totalPaid;
// totalUnpaid is index 4 of the array
$totalUnpaid = compareColumnDesc($x, $y, 4);
if($totalUnpaid != 0) return $totalUnpaid;
// arrays were equal
return 0;
}
$record = array(
array(1, 'marc', 12, 5, 7),
array(5, 'berty', 30, 12, 18),
array(7, 'sarah', 19, 12, 7)
);
// sort your array
usort($record, 'compare');
// print sorted array
echo 'pre';
var_export($record);
echo '/pre';
[/code]

On the topic of my array, what would be an efficient way of checking my

The text file contains username and passwords in the following format:
username1,password1

$p = trim($_POST['pwd']);
$lines = file('/you/pwd/file');
$users = array();
foreach ($lines as $line) {
list($usr, $pwd) = explode(',',$line);
$users[ $usr ] = $pwd;
}
if (isset($users[ $u ]) ($users[ $u ] === $p)) {
echo Found {$u}, and password is correct.;

[PHP] Return Values Copied? Copied if By Reference?
Is a function return value copied? If the value is an integer I suppose
it is but what about a string or an array? If you pass by reference is
the return value still copied?
For example, is this:
function foo($arr) {
$arr[] = bar;
}
faster than this?
function foo($arr) {
$arr[] = bar;
return $arr; // is this copied?
}
I'm working on some code that would be called to generate a cell in a
possibly large table and therefore a small difference in performance
may have a significant impact.

PHP uses copy-on-write and so copies are essentially shared until such
time as you modify one of them. If you don't need references then copies
are faster than references.
