这篇文章主要介绍了PHP parse_ini_file函数的应用与扩展操作,结合实例形式分析了php扩展parse_ini_file函数解析配置文件相关操作技巧,需要的朋友可以参考下
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:
