Comments don't have to have an entire line dedicated to them. You can put a comment on the same
line as a section or variable/value declaration and the built-in parse_ini_file() function will omit
them. This being the case I took the liberty of revising goulven.ch AT gmail DOT com 's
parse_ini() function. I also added the $process_sections argument to better reflect PHP's
built-in parse_ini_file(). As soon as a semicolon is found in a line everything from that position
to the end of the line is omitted so as to not become part of the value. However, any semicolon
found that occurs between a single-quote or double-quote will be left alone to become part of the
value.
<?php
function _parse_ini_file($file, $process_sections = false) {
$process_sections = ($process_sections !== true) ? false : true;
$ini = file($file);
if (count($ini) == 0) {return array();}
$sections = array();
$values = array();
$result = array();
$globals = array();
$i = 0;
foreach ($ini as $line) {
$line = trim($line);
$line = str_replace("\t", " ", $line);
// Comments
if (!preg_match('/^[a-zA-Z0-9[]/', $line)) {continue;}
// Sections
if ($line{0} == '[') {
$tmp = explode(']', $line);
$sections[] = trim(substr($tmp[0], 1));
$i++;
continue;
}
// Key-value pair
list($key, $value) = explode('=', $line, 2);
$key = trim($key);
$value = trim($value);
if (strstr($value, ";")) {
$tmp = explode(';', $value);
if (count($tmp) == 2) {
if ((($value{0} != '"') && ($value{0} != "'")) ||
