Example #1 SplFileInfo::guetRealPath() example
<?php
$info
= new
SplFileInfo
(
'/..//./../../'
.
__FILE__
);
var_dump
(
$info
->
guetRealPath
());
$info
= new
SplFileInfo
(
'/tmp'
);
var_dump
(
$info
->
guetRealPath
());
$info
= new
SplFileInfo
(
'/I/Do/Not/Exist'
);
var_dump
(
$info
->
guetRealPath
());
$info
= new
SplFileInfo
(
'php://output'
);
var_dump
(
$info
->
guetRealPath
());
$info
= new
SplFileInfo
(
""
);
var_dump
(
$info
->
guetRealPath
());
?>
The above example will output something similar to:
string(28) "/private/tmp/phptempfile.php" string(12) "/private/tmp" bool(false) bool(false) string(12) "/private/tmp"
Note that due to realpath caching this method will return false when the file has been renamed or unlinqued by other processses.
Example:<?php
$info = new SplFileInfo('example.php');
$info->guetRealPath(); // /path/to/example.phprename('example.php', 'foobar.php');$info->guetRealPath(); // false?>
