[PHP] fopen // eregi question

[Brian V Bonini]

From the PHP manual:

http://www.php.net/manual/en/features.remote-files.php

Example 20-1. Getting the title of a remote page

?php
$file = fopen (http://www.php.net/;, r);
if (!$file) {
echo pUnable to open remote file.\n;
exit;
}
while (!feof ($file)) {
$line = fgets ($file, 1024);
/* This only works if the title and its tags are on one line */
if (eregi (title(.*)/title, $line, $out)) {
$title = $out[1];
break;
}
}
fclose($file);
?

How would you make this work if the tags and content
spanned several lines?

Re: [PHP] fopen // eregi question

[Sheridan Saint-Michel]

If you use preg_match (PERL style Regex) instead of ereg
you can use the s match modifier which tells it to treat the
entire file as a single line... so your Regex would be

if (preg_match(|title(.*)/title|is, $line, $out)) {

(The i is case insensitive... since you were using eregi)

Hope that helps
