Instead of doing these last three, just walk through each line of
the file. These tasks are just adding extra overhead.

We can kill these four conditions in two lines of code. (see below)

Dont need this if we are reading directly from the file.

Pehraps something like this:
<?php
$fp = fopen('test.ini', 'r');
while (! feof($fp) ) {
$line = fgets($fp, 1024);
/* dont need this trim, only used for the print line */
$line = trim($line);
print "[$line]\n";
if (preg_match('/^
(?<!\#) (?#>No # in the beginning, not
needed but makes pcre skip it,
much faster if line is a comment)
(\w+) (?# The key must be a word )
\s*=\s* (?# Allow space on both sides of =)
(?(?=") (?# If quoted )
"([^"]*)" (?# Grab all but quoted)
| (?# else )
(\w+) (?# grab the word )
)
/x', $line, $matches) ) {
//print_r($matches);
$content[$matches[1]] = ($matches[2]? $matches[2]: $matches[3]);
}
}
print_r($content);
?>
Ok, i lied it was more than two lines, but I made the regular
expression readable (if you can call it that :) A demo of this can
be seen here:
