阅读、编辑和保存配置文件（php）

我有两个配置文件。一种是ini，一种是php。它们看起来像下面这样。我需要更新数据库文件名，但其余文件必须不变。知道该怎么做吗？

config.ini

; Turning Debugging on
[test]
developer = true

; Production site configuration data
[production]
database.params.dbname   = /var/lib/firebird/data/radek_db.gdb

和setting.php

<?php
/**
The settings file
*/

#This will be done automatically if u want to override it uncomment the next line few lines
/*
    $Path   = 'mainline';

#Database to connect to:
    $Database        =       "radek_db";
?>

您可以使用 file_get_contents() 将文件读取为字符串，对其执行 str_replace() 或 preg_replace() 操作，然后使用 file_put_contents() 保存它吗？

我会将这些全部链接到文档，但我没有建立多个链接的声誉...

编辑：如果您只知道选项的名称，则可以使用preg_match 使用正则表达式查找选项名称（类似于'/^database\.params\.dbname = (.*)$/')，然后对找到的名称执行 str_replace 。

像这样的东西：

$file = file_get_contents('/path/to/config/file');
$matches = array();
preg_match('/^database\.params\.dbname = (.*)$/', $file, $matches);
$file = str_replace($matches[1], $new_value, $file);
file_put_contents('/path/to/config/file', $file);

Could you read the file to a string with file_get_contents(), do a str_replace() or preg_replace() on it, and then save over it with file_put_contents()?

I'd link those all to the documentation, but I don't have the reputation to make more than one link...

EDIT: If all you know is the name of the option, you can use preg_match to find the option name with a regexp (something like '/^database\.params\.dbname = (.*)$/') and then do a str_replace on the name you find.

Something like this:

$file = file_get_contents('/path/to/config/file');
$matches = array();
preg_match('/^database\.params\.dbname = (.*)$/', $file, $matches);
$file = str_replace($matches[1], $new_value, $file);
file_put_contents('/path/to/config/file', $file);
