Description:
------------
The manual states that ini_set() "returns the old value on success,
FALSE on failure".
When the initial value of a configuration option is an empty string
ini_set() will give a misleading result as shown on the test case below.
This bug is related to 41922.
The ini_set() code which causes the problem is:
old_value = zend_ini_string(Z_STRVAL_PP(varname),
Z_STRLEN_PP(varname)+1, 0);
/* copy to return here, because alter might free it! */
if (old_value) {
RETVAL_STRING(old_value, 1);
} else {
RETVAL_FALSE;
}
So if response is NULL we set a return code of FALSE.
Reproduce code:
---------------
--TEST--
Test to make sure that ini_set returns old value on success, false on
failure
--FILE--
<?php
var_dump(ini_get("error_log"));
var_dump(ini_set("error_log","/tmp/log"));
var_dump(ini_get("error_log"));
?>
--EXPECT--
string(0) ""
string(0) ""
string(8) "/tmp/log"
Expected result:
----------------
See above
Actual result:
--------------
bool(false) <-- see bug 41922
bool(false) <-- implies ini_set() failure, it actually succeeds.
string(8) "/tmp/log"
