stream_is_local()

(PHP 5 >= 5.2.4, PHP 7)

Checks if a stream is a local stream

说明

Checks if a stream, or a URL, is a local one or not.

参数

The streamresourceor URL to check.

返回值

成功时返回TRUE，或者在失败时返回FALSE。

范例

Example #1stream_is_local()example

Basic usage example.

以上例程的输出类似于：

bool(false)
bool(true)

but hhvm for `file://shouldbelocal.jpg` returns true
https://3v4l.org/ULCni

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)

this is not a bug
mounting a remote filesystem locally "imports" it so it is available to userland programs like a local directory.

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).
