[PHP] fpassthru() error after update
Hi, i use fpassthru() to "stream" video files in my webserver. I worked fine for weeks but yesterday, after updating the webserver, i get the error "Allowed memory size of 268435456 bytes exhausted (tried to allocate 1729609729 bytes) in ." Now PHP version is 5.2.11. Any ideas? Thanks Alessandro -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] fpassthru() error after update
This means that buffered video exceeded your memory limitof 260MB set in your php.ini. Consider increasing it to higher value, if your computer has say 1GB or more of RAM.

[PHP] problem in Computing hash of certificates
Hi all,
I was willing to match two certificates using hash fn but the problem
is when I fetch the certificate from apache its in pem format and when
I fetch the cert from LDAP its in der so only this one needs
to be converted to .pem format which I m doing but its showing me two
diff. hashes.
When I read the cert from LDAP and convert it to pem then it cannot
print also when I use parse function and when print the cert then
inside the BEGIN and END it doesn't print the whole certificate.
Is it normal or it can't fetch the whole cert from ldap?
";
openssl_x509_export ($loginCert, $login_cert_String);
if (empty ($login_cert_String)) echo "empty";
$login_cert_hash = hash ($HASH_ALG, $login_cert_String);
echo "Browser HASH= ". $login_cert_hash;
//$ssl=openssl_x509_parse($loginCert);
//print_r ($ssl);
echo "";
$cn="John Albert";
$dn = "dc=example, dc=com";
$filter="(cn=$cn)";
$justthese = array("userCertificate;binary","cn");
$sr=ldap_search($ldapconnect, $dn, $filter, $justthese);
$info = ldap_get_entries($ldapconnect, $sr);
$entry =ldap_first_entry($ldapconnect, $sr);
$attributes = ldap_get_attributes($ldapconnect,$entry);
$certificate =$attributes["userCertificate;binary"][0];
//convert certificate into .PEM format for further processing.
//$cert2= der2pem($certificate);
$pem = chunk_split(base64_encode($certificate), 64, "\n");
$pem = "-BEGIN CERTIFICATE-\n".$pem."-END CERTIFICATE-\n";
$cert2 = $pem;
// It does not print the certificate as array here
$ssl2=openssl_x509_parse($cert2);
print_r ($ssl2);
echo "";
// here it prints the certificate but it doesn't print the whole
certificate between the BEGIN CERTIFICATE and END CERTIFICATE
// Does that mean it can't read the whole centent.
echo $cert2;
//openssl_x509_export($cert2,$certS);
echo " LDAP HASH:";
echo hash("md5",$cert2);
?>
thanks in advance.

Re: [PHP] fpassthru() error after update
I forgot to mention that you will need to restart your web server after after making that change. Like I mentioned earlier, the script streaming the video is trying to access more memory than the accessible 260MB, by any php script on that server On Sat, Dec 12, 2009 at 12:51 PM, Vincent Tumwijukye wrote: > This means that buffered video exceeded your memory limitof 260MB set in > your php.ini.

The only thing I can obviously see is that you've told it to ignore
transparency on $img2 by not asking it to preserve it (the default is to
ignore). PNG doesn't handle transparency in the same way a GIF does,
each pixel can have a varying degree of opacity, which allows whatever
is beneath it to show through. Add the imagesavealpha($img, true); line
for $img2 and see what that does for you.

Re: [PHP] Server-side encryption to prevent form hacking: new idea?
Suppose you have the following array:
*
*
which is used to generate the following "Select":
*
Tehran
Isfahan
Tabriz
*
You can check whether the submitted value is valid or not, using the
following code:
*if ($_SERVER['REQUEST_METHOD'] == "POST") {
if (!in_array($_POST['city'], $cities) die('Invalid');
}
*
Hope this helps.

Re: [PHP] move_uploaded_file
This is exactly what I mean.
Documentation should never leave room to interpretation.

I can't see where you would find fault with the documentation though, as
all the PHP file functions require either an absolute path from the root
(not web root) or a relative one from the script performing the action.

Re: [PHP] Transparent PNGs: Merging
Hi Ash,
Thanks for your suggestion. Unfortunately,that did not help but i've found a
post via Google which gave a simple (and slightly counter-intuitive)
solution - replace
imagecopymerge($img2, $img, $yoffset, 5, 0, 0, imagesx($img), imagesy($img),
100);
with
imagecopy($img2, $img, $yoffset, 5, 0, 0, imagesx($img), imagesy($img));
And it works :)
It seems imagecopymerge does not work well with PNGs and Alpha Channels.
Many thanks for your help,
Alex

Re: Re: [PHP] move_uploaded_file
It's also a security flaw... php should be chrooted to the webroot! Or
it should be chrooted to the users home directory. Especially on windows
systems where security is not so strict.
My 2 cents,
Carl.

Re: Re: [PHP] Backup to local drive
Two words: Java Applet.. That's the stuff that Facebook and other social sites do stuff like this, Although I've only seen it for upload. One thing perhaps you can do is have the applet command the browser to save the page as a complete web page onto the flash drive. it's cross platform and cross browser compatible... Also, maybe with some JQuery plugins you can have what you need. Hoping that inspires/helps, Carl.

Then hundreds of apps that use PHP to deliver files outside of web root
after a user has passed security validation would fail to work, and that
is just to name one specific example, as it's something I've used on
many sites. You'd lose access to a whole host of shell functionality,
because often the programs people call from the shell are not in the
PATH env variable for the user that Apache runs under (this is different
from the include path that Apache or PHP itself has). In my opinion,
chrooting PHP to the web root would cause major problems.

I can prevent form hacking by simply checking and scrubbing incoming data without resorting to encryption. Security techniques are very basic and it's probably best if you read a book on the subject. I recommend Essential PHP Security by Chris Shiflett. You can pick it up at Amazon for less than $20. It's a good read with lot's of useful information. The $20 bucks you spend on that will save you more in time than trying to reinvent the security wheel.

If you use Prototype and Scriptaculous (the GUI side of things for effects and such), then you've got a winner. Something that is missing though is the more GUI-like components that come with toolkits like BlueShoes (php CMS server and client side with separatable JS components - license required depending upon usage). For just the AJAX communication, then prototype is perfectly adequate. Though the 'X' is often easier to work with if it is J as in JSON. Prototype can return JS objects from an AJAX call. PHP support for JSON is fine in this regard (though I would make sure you set JSON_FORCE_OBJECT for json_encode() to make sure empty arrays are returned as objects rather than an empty array if you are building your objects dynamically).

Re: [PHP] move_uploaded_file
Depends on the configuration. If I have a bunch of web sites and they
are all using files created, written and executed by the apache user,
when the apache process sudo execs the php from a specific web root I
want it to stay in that root. I don't want it to be able to write files
to another web root.
Believe me, I know administrators who have issues with php precisely
because of this. It is especially true if you are using VirtualHosts.
And even more true if you are using VirtualHosts with different users
controlling those hosts. You a) have to be very careful about users,
groups and permissions or b) chroot your php process. a) is much much
simpler.. as long as the apache process can read the files you're
golden. However on Windows, this is, of course, impossible; or at least
very highly improbable.

Re: [PHP] file_get_contents ($file) works -- file_get_contents ($url) returns false
Hi Rene,
The only thing which is a hurdle is that your system/computer is not
allowing external connections. There seems to be nothing else wrong.
I strongly suggest check your system firewall, any central server settings
through which your system gets internet access, any antivirus s/w installed
etc.. this can be the only reason. Something is stopping you to access
external connection.
Let me know when your problem is fixed.
Also I tried the below code and it works fine-
http://www.google.com');
echo $str;
?>

O'Reilly is good for getting the facts. You could start with Programming PHP: http://oreilly.com/catalog/9781565926103/ Check the O'Reilly PHP page for more resources, some printed: http://oreilly.com/php/ If you're looking for books that specifically cover PHP's OO features, there are lots of older books on pre-5.3 features, like Zandstra's PHP 5 Objects, Patterns, and Practice (2004): http://www.amazon.com/PHP-5-Objects-Patterns-Practice/dp/1590593804/ref=sr_1_3?ie=UTF8&s=books&qid=1260652305&sr=8-3 Although if you're new to OOP you may want to read more general books on the subject and then work your way back to the features available in the version of PHP that you need to use. In general, the best publishers I've found are O'Reilly, The Pragmatic Programmers, Apress and Packt.

Re: [PHP] file_get_contents ($file) works -- file_get_contents ($url) returns false
The thing is, the file_get_contents() fails the same way on local URLs -- that
is, web sites hosted on the same machine. Or even using the machine's own IP
address.

Re: [PHP] Best ajax library
Well I would recommend jQuery for client-side ajax.
