php_ini_all 7 该项目可以在任何地方设定

ini_set ini_get 可操作配置参数列表

获取 magic_quotes_gpc 状态,来决定当表单提交时我们是否转义(addslashes)数据;

设定 max_execution_time 来延长 程序的执行时间;

设定 error_reporting 使自己的项目在开发与运营阶段切换;

设定 memory_limit 加大内存等等…

view sourceprint?1 ini_set (string varname, string newvalue ) :  //设定环境配置的参数    

2 ini_get (string varname) :  //获取环境配置的参数

 php ini_set函数是设置选项中的值,在执行函数后生效,脚本结束的时候,这个设置也失效。不是所有的选项都能被改函数设置的。具体那些值能够设置,可以查看手册中的列表。

就是能够设置php.ini中的选项值比如,display_error选项关闭 了,但是你要显示程序中的错误信息,方便你调试程序,那么就可以使用php ini_set函数:

view sourceprint?1 ini_set ( 'display_errors' ,  'on' );

 那么在你这个页面的程序都会显示错误信息了,而且你还可以使用error_reporting来设置显示的错误信息级别。

 如果你需要增加脚本执行时间,那么可以设置:

view sourceprint?1 ini_set('max_execution_time', '180');

 那么脚本执行时间就由默认的30秒变为180秒,当然,你也可以使用set_time_limit()来设置。

 其实你把php ini_set函数和ini_get结合使的话,非常好。比如你想在配置文件里添加自己的包含文件路径,但是你有没有权限更改php.ini,那么你可以 结合两个函数:

view sourceprint?1 ini_set ( 'include_path' , ini_get ( 'include_path' ). ':/your_include_dir:' );

php配置函数ini_get()相信很多人都使过,就是获取配置文件中某一个选项的值,如果是true值就返回1,如果是false值就返回0,字符串就返回字符串。

比如手册中的例子:

view sourceprint?1

2 /* our php.ini contains the following settings: display_errors = on register_globals = off post_max_size = 8m */    

3     

4 echo   'display_errors = '  .  ini_get ( 'display_errors' ) .  " " ;  //显示错误是否打开     

5 echo   'register_globals = '  .  ini_get ( 'register_globals' ) .  " " ;  //全局变量是否打开     

6 echo   'post_max_size = '  .  ini_get ( 'post_max_size' ) .  " " ;  //最多能提交的文件大小     

7 echo   'post_max_size+1 = '  . ( ini_get ( 'post_max_size' )+1) .  " " ;    

8     

9 ?>

输出:

  display_errors = 1

  register_globals = 0

  post_max_size = 8m

  post_max_size+1 = 9

  php配置函数ini_get()主要是为了获取配置文件,可以方便你很多操作。 比如你想操作字符串过滤,但是又不清楚 magic_quotes_gpc有没有打开,所以你就可以这样写一个函数:

view sourceprint?1

2  /* 字符串过滤函数 */    

3 function  stringfilter( $str ) {    

4     if  ( ini_get ( 'magic_quotes_gpc)' ) {  return   $str ; }  else  {  return   addslashes ( $str ); }    

5 }   

6 ?>

当然,如果你无法知道你的全局变量是否打开,也可以定制这样的函数:

view sourceprint?1

2 /* 变量检测函数 */    

3 function  getgetvar( $var ) {    

4     if  ( ini_set ( 'register_gobals' )){  return   $var ; }  else  {  return   $_get [ 'var' ]; }    

5 }   

6 ?>

 当然,你可以用php配置函数ini_get()做很多用途
