realpath_cache_get — Get realpath cache entries
Get the contents of the realpath cache.
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.
Example #1 realpath_cache_get() example
<?php
var_dump(realpath_cache_get());
?>
The above example will output something similar to:
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.
