如何为Fopen转义URL [英] How to escape url for fopen

问题描述

fopen似乎无法打开带空格的文件. 例如:

It looks like fopen can't open files with spaces. For example:

$url = 'http://gatewaypeople.com/images/articles/cntrbutnssttmnts12_main 616x200.jpg';
fopen($url, 'r'); 

返回false(注意url中的空格)，但是浏览器可以访问该文件. 我也尝试通过urlencode和rawurlencode转义URL，但是没有运气.如何正确避开空间?

returns false (mind the space in the url), but file is accessible by browsers. I've also tried to escape the url by urlencode and rawurlencode with no luck. How to properly escape the spaces?

推荐答案

您可以使用以下代码:

$arr = parse_url ( 'http://gatewaypeople.com/images/articles/cntrbutnssttmnts12_main 616x200.jpg' );
$parts = explode ( '/', $arr['path'] );
$fname = $parts[count($parts)-1];
unset($parts[count($parts)-1]);
$url = $arr['scheme'] . '://' . $arr['host'] . join('/', $parts) . '/' . urlencode ( $fname );
var_dump( $url );

Alternative & Shorter Answer (Thanks to @Dziamid)

$url = 'http://gatewaypeople.com/images/articles/cntrbutnssttmnts12_main 616x200.jpg';
$parts = pathinfo($url);
$url = $parts['dirname'] . '/' . urlencode($parts['basename']);
var_dump( $url );

输出:

string(76) "http://gatewaypeople.com/images/articles/cntrbutnssttmnts12_main+616x200.jpg"
