Question
"Dialectizer" in PHP.. fun project :D
OK, so I am trying to make my own Dialectizer type thing (based on the concept behind http://rinkworks.com/diale
I am usually pretty PHP competent, but this time I have failed.
Basically what I need it to do, is get a URL, and replace any instance of abc with xyz. I got that far.
Heres are the things I can't figure out (not yet anyway),
It must convert all relative image and CSS links to absolute links pointing to where they should
It has to point all relative links through the dialectizer as well
So, I thought I would throw it out here and see if anyone could help me out with the code..
Heres my code so far:
<?php
if ($_GET['url']) {
// grab out put from page
ob_start();
include($_GET['url']);
$pagecontent = ob_get_contents();
ob_end_clean();
// modify output
$pagecontent = eregi_replace("http://" , 'index.php?url=http://', $pagecontent);
$pagecontent = eregi_replace("ing", "in'", $pagecontent);
$pagecontent = eregi_replace("and", "an'", $pagecontent);
$pagecontent = eregi_replace("for", "fo'", $pagecontent);
$pagecontent = eregi_replace("broken", "busted", $pagecontent);
$pagecontent = eregi_replace("what", "whut", $pagecontent);
$pagecontent = eregi_replace("ever", "evah", $pagecontent);
$pagecontent = eregi_replace("tion", "shun", $pagecontent);
$pagecontent = eregi_replace("potatoe", "tater", $pagecontent);
//etc..
// write output to page
echo $pagecontent;
} else {
?>

For a start I'd suggest that you build arrays of match patterns and replacements so you can do it all in one pass. It will be much faster:
$in=array('ing', 'and', 'for'); //etc
$out = array('in', 'an', 'fo');
$translation = preg_replace($in, $out, $pagecontent);
You only need to redirect <a> tag links through your script, so your search for "http" etc is too wide. Try:
$pagecontent = preg_replace('/(<\s*a\s+.*
This also copes with links where the href is not the first attribute in an a tag, varying spacing, case insentitive.
You still need to convert images and CSS style or link meta tags to absolute URLs, along with form submission actions - I'll leave that for someone else, but you might find parse_url() and realpath() useful.
