stream_get_filters — 获取已注册的数据流过滤器列表
获取当前运行系统中已注册的数据流过滤器列表。
返回一个包含所有有效的数据流过滤器名字的索引数组。
Example #1 使用 stream_get_filters()
<?php
$streamlist = stream_get_filters ();
print_r ( $streamlist );
?>
以上例程的输出类似于:
Array ( [0] => string.rot13 [1] => string.toupper [2] => string.tolower [3] => string.base64 [4] => string.quoted-printable )
[#1] Jasper Bekkers [2005-10-05 11:53:20]
Filters to be used within the convert filter are base64-encode, base64-decode, quoted-printable-encode and quoted-printable-decode. Note: those are not in the string filter, as currently reported by the manual!
Example usage is:
<?php
$h = fopen('gecodeerd.txt', 'r');
stream_filter_append($h, 'convert.base64-decode');
fpassthru($h);
fclose($h);
?>
Or
<?php
$filter = 'convert.base64-decode';
$file = 'coded.txt';
$h = fopen('php://filter/read=' . $filter . '/resource=' . $file,'r');
fpassthru($h);
fclose($h);
?>
