PHP - Parse ini file and access single values - php

Question

In Python you can parse an .ini file and access the single values like this:
myini.ini
[STRINGS]
mystring = fooooo
value = foo_bar
script.py
import configparser
config = configparser.ConfigParser()
# ----------------------------------------------------------------------
config.read("myini.ini")
test = config["STRINGS"]["mystring"]
print (test) #-> OUTPUT: fooooo
How can I do the same in PHP? Unfortunately, I was not able to find any examples.

Answer 1

Not to fear, parsing an .ini file is a standard method. (See parse_ini_file in the php docs).
Using your file as the base of this example:
myini.ini
[STRINGS]
mystring = fooooo
value = foo_bar
test.php
$ini_array = parse_ini_file("myini.ini");
print_r($ini_array); # prints the entire parsed .ini file
print($ini_array['mystring']); #prints "fooooo"
Note that by default parse_ini_file ignores sections and gloms all ini settings into the same object. If you'd like to have things scoped sectionally as in your python example, pass true for the process_sections parameter (second parameter).
test2.php
$ini_array = parse_ini_file("myini.ini", true /* will scope sectionally */);
print($ini_array['mystring']); #prints nothing
print($ini_array['STRINGS']['mystring']); #prints fooooo

Answer 2

From the intermediate approach, to get match section, it needs to read any INI file from line to line, in this case you can use fgets function or stream_get_line function to read for each line until the section founded or end of file (not founded).
Inside every line we can use preg_match (using regex pattern) that match with the actual section name been searched.
The essential of this approach is to reduce memory usage meanwhile many concurrent request occurs at the same time, so in this case we use string object with any sufficient length as a buffer.
Good luck Buddy.
