You may want, in some very special cases, to parse multi-dimensional array with N levels in your ini
file. Something like setting[data][config][debug] = true will result in an error (expected
"=").
Here's a little function to match this, using dots (customizable).
<?php
function parse_ini_file_multi($file, $process_sections = false, $scanner_mode = INI_SCANNER_NORMAL)
{
$explode_str = '.';
$escape_char = "'";
// load ini file the normal way
$data = parse_ini_file($file, $process_sections, $scanner_mode);
if (!$process_sections) {
$data = array($data);
}
foreach ($data as $section_key => $section) {
// loop inside the section
foreach ($section as $key => $value) {
if (strpos($key, $explode_str)) {
if (substr($key, 0, 1) !== $escape_char) {
// key has a dot. Explode on it, then parse each subkeys
// and set value at the right place thanks to references
$sub_keys = explode($explode_str, $key);
$subs =& $data[$section_key];
foreach ($sub_keys as $sub_key) {
if (!isset($subs[$sub_key])) {
$subs[$sub_key] = [];
}
$subs =& $subs[$sub_key];
}
// set the value at the right place
$subs = $value;
// unset the dotted key, we don't need it anymore
unset($data[$section_key][$key]);
}
// we have escaped the key, so we keep dots as they are
else {
$new_key = trim($key, $escape_char);
$data[$section_key][$new_key] = $value;
unset($data[$section_key][$key]);
}
}
}
}
if (!$process_sections) {
$data = $data[0];
}
return $data;
}
?>
The following file:
<?php
/*
[normal]
foo = bar
; use quotes to keep your key as it is
'foo.with.dots' = true
[array]
foo[] = 1
foo[] = 2
[dictionary]
foo[debug] = false
foo[path] = /some/path
[multi]
foo.data.config.debug = true
foo.data.password = 123456
*/
?>
will result in:
<?php
parse_ini_file_multi('file.ini', true);
Array
(
[normal] => Array
(
[foo] => bar
[foo.with.dots] => 1
)
[array] => Array
(
[foo] => Array
(
[0] => 1
[1] => 2
)
)
[dictionary] => Array
(
[foo] => Array
(
[debug] =>
[path] => /some/path
)
)
[multi] => Array
(
[foo] => Array
(
[data] => Array
(
[config] => Array
(
[debug] => 1
)
[password] => 123456
)
)
)
)
?>
