PHP and Perl in One Script?
gbulmash asks: "Recently, I began working on a graphics project and wanted to use ImageMagick. As a PHP coder, I figured I'd use MagickWand for PHP. But after some investigation, I decided that an alpha at 0.1.8 with sparse documentation just wasn't going to be good enough for production use. I decided that PerlMagick would be a much better API, but I didn't want to code the whole project in Perl. In the end, I found a cool package for embedding Perl code in PHP scripts (with an article on its use) and it went to a 1.0.0 release, earlier this year. I think I've found my answer, but before I make a final decision and go ahead with it, I thought I'd ask the knowledgeable Slashdot crowd: Is there a better way of interfacing Perl with PHP so you can get the best of both worlds?"
So you've got Perl in your PHP, is there a way to do PHP in your Perl?
Why didn't you use the ImageMagick extension in PECL? There's plenty of image processing options with PHP, just because MagickWand didn't work out for you, that doesn't mean you have to concoct a monstrous hybrid of PHPerl.

Instead of going with some bizarre rube-goldberg hack like this (does it even work with dynamically loadable Perl modules?), just write a separate Perl script that does what you need and receives data on standard input and gives responses on standard output. Use PHP's proc_open() function. You can even set up the Perl script as a daemon, if you like, and get higher performance.
I used this same trick to interface a binary-only executable to my PHP script. You can even use XML to pass the data back and forth, if you swing that way. I don't know how this might work on Windows, if that's what you're running on.
By the way, version numbers mean absolutely nothing except the author's opinion of his own software. In fact, the article you posted says: "the extension is still marked EXPERIMENTAL". Sounds like alpha to me.
Not to mention, this is the same guy that wrote Turck MMCache and in my testing, mmcache couldn't stay stable for more than a day or two, and would randomly return junk characters instead of output from our PHP scripts. Not exactly an author I'd trust for this kind of lower-level stuff. (Yeah, I know, there are 10 billion geeks who used MMCache on their 5-hit-per-day blog and it worked perfectly, and will not hesitate to point this out. It just didn't work for me, and other products did, sorry!)
For what it's worth, I've used "pecl-imagick-0.9.11" on my Gentoo servers to manipulate images (basically, to generate thumbnails by resizing and sharpening) and it works perfectly. I think this is different than what you're talking about. So unless you really just can't live without Perl (?), try that first.
Instead of looking at version numbers, test thoroughly.
All the security of PHP and all the readability of Perl? It's a surefire win. I wonder why the whole world hasn't caught on to this one yet?

I'm probably going to get flamed for this but have you considered using rails? Seriously, you just spend a couple of hours installing it on your development box before you discover the speed and power of rails. Then when you've used the programming equivilent of a lumphammer to sculpt your fine detailed script, you get to spend the next week looking for hosting. I do all my development on a gentoo box, it only took me a weekend to set up from stage 1. I have some great USE flags that make my RAILS development go super fast and gentoo only takes about 1.5 hours a week to maintain. Well, sometimes it takes a little longer because the QA is non-existent of late.
That's what I'd do anyway, RoR running on gentoo with some kicking USE flags. I'm developing a complete Ajax OS in my spare time using this system. It's going to revolutionize the OS market and yes, it will have use flags.
Erm... how about
Yes, it uses references, but if you're scared of them, pretend it's a 'real' multidimensional hash.
Bit off-topic, but if you need those kinds of features (compilers, custom Perl modules, etc.) maybe check out one of the user-mode Linux Web hosts like Linode.com – they've been running my site for a few months, and I'd say it's probably the best thing since Al Gore invented the Interwebs :-) You get your own distribution, your own choice of server configurations... it's like a dedicated server without the dedicated server. [Not trying to sound like an advertisement or anything like that, just a very happy user recommending a useful service.]
Creative misinterpretation is your friend.

Why do you need them to work in the same script? Have your PHP generate an img tag that references the perl script in the src attribute. Then the web browser will fetch the image data directly from the perl script and you don't need a Frankensteinian monster.
