本文实例讲述了PHP parse_ini_file函数的应用与扩展操作。分享给大家供大家参考，具体如下：

parse_ini_file($filename, $process_sections = false, $scanner_mode = INI_SCANNER_NORMAL)解析一个配置文件。

filename要解析的文件名；

process_sections设置为true时，得到一个多维数组，包括配置文件中每一节的名称和设置，默认为false;

解析成功返回关联数组，失败返回false。列举一下官网的例子，也引用了官网的扩展实例parse_ini_file_multi()。

下面是配置文件内容：

[first_section] one = 1 two = 2 name = test [second_section] path = '/tmp/test' url = 'http://test.com/login.php' [third_section] php_version[] = '5.0' php_version[] = '5.1' php_version[] = '5.5' [dictionary] foo[debug] = true foo[path] = /some/path [fourth_section] fold1.fold2.fold3 = 'a' fold1.fold2.fold4 = 'b' fold1.fold2.fold5 = 'b'

下面是PHP文件内容：


function parse_ini_file_multi($file, $process_sections = false, $scanner_mode = INI_SCANNER_NORMAL){
 $explode_str = '.';
 $escape_char = "'";
 $data = parse_ini_file($file, $process_sections, $scanner_mode);
 if (!$process_sections) {
 $data = array($data);
 }
 foreach ($data as $section_key => $section) {
 foreach($section as $key => $value){
 if(strpos($key, $explode_str)){
 if(substr($key, 0, 1) !== $escape_char){
 $sub_keys = explode($explode_str, $key);
 $subs =& $data[$section_key];
 echo "\r\n".'========='."\r\n";
 print_r($subs);
 print_r($data);
 foreach($sub_keys as $sub_key){
 if (!isset($subs[$sub_key])) {
 $subs[$sub_key] = [];
 }
 $subs =& $subs[$sub_key];
 echo "\r\n".'++++++++'."\r\n";
 print_r($subs);
 print_r($data);
 }
 $subs = $value;
 echo "\r\n".'----------'."\r\n";
 print_r($subs);
 print_r($data);
 unset($data[$section_key][$key]);
 }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;
}
$arr = parse_ini_file('file.ini');
print_r($arr);
echo "\r\n".'================='."\r\n";
$arr = parse_ini_file_multi('file.ini',true);
echo "\r\n".'================='."\r\n";
print_r($arr);

运行结果：
