PHP开发笔记系列(五)- INI文件解释

??? 在JAVA开发中,我们经常会用到properties文件来保存整个工程需要用到的配置信息,例如数据库的连接串、用户名、密码、文件上传目录等等,那么PHP中这样的配置信息是怎样保存的呢?本文《PHP开发笔记系列(五)- INI文件解释》 将是《PHP开发笔记系列(XAMPP+PhpEclipse+XDebug)》 的第五篇,讲述如何解释INI配置文件。

??? 在PHP中,通常使用ini文件来保存配置信息,在一个.ini文件中建立变量,然后用parse_ini_file函数在代码中包含这个文件,该函数讷讷够解释与php.ini相同格式的文件。

??? 为了方便起见,直接从%XAMPP_HOME%/php目录下,copy一份php.ini文件到php工程下, 实验php脚本的解释.

?

????? INI文件是Initialization File的缩写,即初始化文件。是windows的系统配置文件所采用的存储格式。INI文件由节、键、值组成。 是[section],参数(键=值): name=value,注解使用分号表示(;)。在分号后面的文字,直到该行结尾都全部为注解。以下是Xdebug.ini文件样例:

?

[Xdebug]
xdebug.profiler_enable=on
xdebug.trace_output_dir=D:\xampp\php\tmp\xdebug
xdebug.profiler_output_dir=D:\xampp\php\tmp\xdebug
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost
xdebug.remote_port=9000 
xdebug.auto_trace = On
xdebug.show_exception_trace = On
xdebug.remote_autostart = On
xdebug.remote_enable = On
xdebug.collect_vars = On
xdebug.collect_return = On
xdebug.collect_params = On

?

? ??? parse_ini_file()函数可以设定是否解释section片段,下面将对上面的xdebug.ini文件进行解释,分别返回一维和二维数组:

?

file:ini1.php
url:http://localhost:88/ini/ini1.php
<?php $filename= 'xdebug.ini';
    
    // 指定ini文件路径,设定不解释section,结果为一维数组
    $vars = parse_ini_file($filename);
    
    echo '<h1>Ini File Content:<br>';
    echo '<pre class="brush:php;toolbar:false">';
    print_r($vars);
    echo '
'; echo '
'; echo '
';
    // 通过数组索引(一维)访问配置信息
    echo 'xdebug.remote_host='.$vars['xdebug.remote_host'].'<br>';
    echo 'xdebug.remote_port='.$vars['xdebug.remote_port'].'<br>';
    echo '
'; ?>

?

?

file:ini2.php
url:http://localhost:88/ini/ini2.php
<?php $filename= 'xdebug.ini';
    
    // 指定ini文件路径,设定解释section,结果为二维数组
    $vars = parse_ini_file($filename, TRUE);
    
    echo '<h1>Ini File Content:<br>';
    echo '<pre class="brush:php;toolbar:false">';
    print_r($vars);
    echo '
'; echo '
'; echo '
';
    // 通过数组索引(二维)访问配置信息
    echo 'xdebug.remote_host='.$vars['Xdebug']['xdebug.remote_host'].'<br>';
    echo 'xdebug.remote_port='.$vars['Xdebug']['xdebug.remote_port'].'<br>';
    echo '
'; ?>

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
