How to transform an INI file into an Array? [duplicate]

If you use parse_ini_file it will interpret without the sessions, something like:

Array
(
    [host] => localhost
    [password] => sabe_de_nada_inocente
    [port] => 3306
)

But if you apply the second parameter parse_ini_file('arquivo.ini', true); then you have this:

Array (
   [database] => Array (
        [host] => localhost
        [password] => sabe_de_nada_inocente
        [port] => 3306
    )
)

If the content comes from a string then use parse_ini_string , like this:

<?php

$data = '[database]
host = localhost
password = sabe_de_nada_inocente
port = 3306';

print_r(parse_ini_string($data, true));

Some details that have changed:

• PHP 5.3.0

  Added the third parameter, scanner_mode , single quotes (apostrophes) are used to set the variable and are no longer part of their value.

  Hashes # should not be used for comments, use ; , using the hash will cause a warning, as it is deprecated, even though parse_ini_* still interprets the hash as comment.

• PHP 5.6.1

  Added mode INI_SCANNER_TYPED , in the third parameter.

• PHP 7.0.0

  Hashes are finally no longer used as comments and cause a parse error if you try to use them.

Using the scanner_mode mode

If you have a .ini like this:

[foo]
baz = true
bar = false
foobar = On
foobaz = Off

And do this:

<?php

var_dump(parse_ini_file('meu.ini', true));

Will return this, string with value 1 if true or On , or empty string if Off or false :

array(1) {
  ["foo"]=>
  array(4) {
    ["baz"]=>
    string(1) "1"
    ["bar"]=>
    string(0) ""
    ["foobar"]=>
    string(1) "1"
    ["foobaz"]=>
    string(0) ""
  }
}

Note that if you use quotation marks or apostrophes it will not parse to 1 or empty, similar to INI_SCANNER_RAW :

baz="true"
bar="false"
foobar= "On"
foobaz="Off"
testnumer="0"

If you use INI_SCANNER_RAW (PHP 5.3.0 +)

<?php

var_dump(parse_ini_file('meu.ini', true, INI_SCANNER_RAW));

It will not parse from On, Off, true and false, will all string "literals":

array(1) {
  ["foo"]=>
  array(4) {
    ["baz"]=>
    string(4) "true"
    ["bar"]=>
    string(5) "false"
    ["foobar"]=>
    string(2) "On"
    ["foobaz"]=>
    string(3) "Off"
  }
}

<?php

var_dump(parse_ini_file('meu.ini', true, INI_SCANNER_TYPED));

Return this:

array(1) {
  ["foo"]=>
  array(4) {
    ["baz"]=>
    bool(true)
    ["bar"]=>
    bool(false)
    ["foobar"]=>
    bool(true)
    ["foobaz"]=>
    bool(false)
  }
}

Use the parse_ini_file () function. If there are 'fields' with the same name, the last one will enter as key in the array. To avoid this situation, pass true as the second argument, so the array will be separated by sessions.

config.ini

[database]
host = localhost
password = sabe_de_nada_inocente
port = 3306
[ftp]
user = admin
password = admin1234

php:

$arr = parse_ini_file('config.ini', true);

echo "<pre>";
print_r($arr);

Output:

Array
(
    [database] => Array
        (
            [host] => localhost
            [password] => sabe_de_nada_inocente
            [port] => 3306
        )

    [ftp] => Array
        (
            [user] => admin
            [password] => admin1234
        )

)

Without informing the second argument, the return is:

Array
(
    [host] => localhost
    [password] => admin1234
    [port] => 3306
    [user] => admin
)
