<div dir="ltr"><div>Facebook hasn't had any hacks that I am aware of. I know they release a lot of information via Graph and other areas, which leads many of us to feel uncomfortable with there security practices. But it seems all the information that is released, is released by design. And I don't see how just because they run PHP through HipHop (which they created) to run there code through C and C++ for <i>performance reasons</i> makes it anymore secure than standard PHP?</div>
<div><br></div><div>Also, just because PHP can be written poorly and that it attracts beginner developers, doesn't mean that it is by itself an insecure language - it just means those applications with poor coders are insecure. Also, your reason #3 would speak to the inefficiency of PHP but I don't see how it speaks to the insecurity of PHP.</div>
<div><br></div><div>To me the larger issue always seems to be with code that is available for public distribution (i.e. WordPress, phpBB, etc...). If people can peer into the code and find the vulnerabilities and exploit un-updated versions of it, it makes sense that <i>they</i> are insecure. But not that the platform itself is insecure. But if you're code is never released publicly, and you take good measure to secure the server (which is more of a Linux thing anyways assuming a LAMP stack), then how is it PHP's fault?</div>
<div><br></div><div>Also, isn't SQL injection pretty much fixed with Magic Quotes? I had a security guy from GA Tech test my site once and was unable to SQL inject attack the site. I thought this was largely due to the fact that any $_POST to the site is automatically escaped via Magic Quotes.</div>

Some points:<br>
<ol>
<li>Facebook does not run the official PHP, they run a subset of
it that is then compiled, if memory serves, to C++ and then
compiled to system code.</li>
<li>PHP itself is insecure for <b>many</b> reasons, the least of
which:</li>
<ol>
<li>PHP has never deprecated functionality that is known-unsafe,
given the average experience of the PHP-only programmer; for
example, SQL injection attacks are pandemic in PHP code not
because it's any less safe than C, but because it is just as
safe as C and PHP-only programmers don't have perspective from
which to draw from to secure their own code. This flaw could
be fixed in PHP by removing functions that permit it; in my
book, that makes it a PHP flaw (it's easier to fix PHP than it
would be to fix all PHP programmers).</li>
<li>PHP has a large number of pseudoprogrammers that work with
it. These people are mostly management types that found that
they can quickly piece together a PHP script and make it do
something useful. These people have no background in
security, information technology, information systems or any
similar such topic. They often C&P pathologically, and
the systems that they create are swiss cheese from a security
perspective. Again, this is something that can be fixed in
PHP, by ensuring that variables that come from the user are
always represented in a canonical format and that outputs are
properly escaped.</li>
<li>PHP has a large number of what I call "auto-fsck-you"
features built-in to it that most people do not understand.
One such example is PHP's associative arrays, which are really
integer arrays. The reason that integers and string keys can
both be used in PHP in the same array is that they share the
same namespace; a very large sequential array is quite likely
to clash with the hashed namespace used for string keys. Fun,
yes? And that's just one example.</li>
</ol>
</ol>
<p>I could go on for pages, but there are many others who have done
so at length; I won't reinvent the wheel here. I can say, though,
that a quick review of US-CERT data shows that PHP and
applications written in it are still among the most common of
security problems—even in systems written by professional
programmers.<span class="HOEnZb"><font color="#888888"><br>
