示例 #1 stream_is_local() example
Basic usage example.
<?php
var_dump(stream_is_local("http://example.com"));
var_dump(stream_is_local("/etc"));
?>以上示例的输出类似于：
bool(false) bool(true)
<?php
$file1 = '/somefile.jpg';
$file2 = 'file://shouldbelocal.jpg';
$file3 = 'http://someotherfile.jpg';
$file4 = 'file:///indeedlocal.jpg'; // Please note '///' instead of '//'
$local = stream_is_local($file1);
$shouldbelocal = stream_is_local($file2);
$remote = stream_is_local($file3);
$indeedlocal = stream_is_local($file4);
var_dump($local, $shouldbelocal, $remote, $indeedlocal);this is not a bug
mounting a remote filesystem locally "imports" it so it is available to userland programs like a local directory.It appears to return incorrectly for 'file://' wrapper which I would consider to be local.
CODE:
$file1 = '/somefile.jpg';
$file2 = 'file://shouldbelocal.jpg';
$file3 = 'http://someotherfile.jpg';
$local = stream_is_local($file1);
$shouldbelocal = stream_is_local($file2);
$remote = stream_is_local($file3);
var_dump($local, $shouldbelocal, $remote);
RESULT:
bool(true)
bool(false)
bool(false)The function stream_is_local() does not work with remote mounts points, like sshfs mount points (it will return true as if it was local).
