realpath_cache_get — Get realpath cache entries
Diese Funktion besitzt keine Parameter.
Returns an array of realpath cache entries. The keys are original path entries, and the values are arrays of data items, containing the resolved path, expiration date, and other options kept in the cache.
Beispiel #1 realpath_cache_get() example
<?php
var_dump(realpath_cache_get());
?>Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
array(2) {
["/test"]=>
array(4) {
["key"]=>
int(123456789)
["is_dir"]=>
bool(true)
["realpath"]=>
string(5) "/test"
["expires"]=>
int(1260318939)
}
["/test/test.php"]=>
array(4) {
["key"]=>
int(987654321)
["is_dir"]=>
bool(false)
["realpath"]=>
string(12) "/root/test.php"
["expires"]=>
int(1260318939)
}
}
Note that the realpath cache is not used if either safe_mode is on or an open_basedir restriction is in effect.
This is having a huge performance effect, causing lots of calls to lstat.
