How many lines of code get run when my script executes?

[pbmods]

Whew! Just got done writing the latest version of my template rendering engine, and it is a BEAST!

I'm very proud of it, and hopefully with my boss' permission, I will be able to open source it soon. But that's not what my question is about.

The class by itself is a little over 1500 lines of code, but I'm pretty sure that PHP actually ends up executing about 5 or 6 thousand lines of code before the first line of HTML gets output (and all in about a quarter of a second [1/8th after the first execution with Zend Optimizer!]... wow!).

Out of curiosity, though, I'd love to know exactly how many lines of code PHP is executing per execution.

Is there a tool out there that can do this? Preferably for Mac / *n?x platforms.

Thanks for your time.

I think I might have found something built into PHP that can do this:
http://php.net/declare

Not sure exactly how to make it do what I want it to, but we'll have some fun, I'm sure!

Nice work pbmods... I remember a big project I worked on when I first started programming PHP, I wrote like 600 lines without ever testing it. I was extatic when it worked the first time! I then realized how stupid that was and vowed never to do that again. Glad to hear about your successful project! Congrats!

sounds interesting :-)
but ...
What the zend optimizer is?

Heya, jx2.

Zend Optimizer is a PHP extension that caches opcode and performs runtime optimizations on PHP code. The end result is that after the first execution, each of your scripts executes much more quickly.

You can find out more about this free utility here:

Hehe I just wrote (and re-wrote three times) a template engine. It only handles conditional statements and looping, but that's all I need so far.

I had it output the entire process once and it chains together multiple templates, parsing and injecting and it does a lot more work than I thought it did in such a short time. Like, 3 seconds in all. Tokenization.. Parsing.. Output... 2 - 5 seconds. Yet, I have another script that takes forever just to print <div>s to the browser window. It's 1000 <div>s, but still. It's like, 3 seconds per 100 <div>s.

Looks like something like this should work, except, what it's counting is number of low-level instructions, not necessarily lines.

function countLine($dump = false)
{
    static $lineCount = 0;
 
    if($dump)
    {
        return $lineCount;
    }
 
    ++$lineCount;
}
 
register_tick_function('countLine');
declare(ticks = 1);
 
.
.
.
 
echo countLine(true), ' lines of code executed.';
