#41922 [Opn->WFx]: ini_get() gives ambiguous result

ID: 41922 Updated by: iliaa@php.net Reported By: zoe at uk dot ibm dot com -Status: Open +Status: Wont fix Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 5CVS-2007-07-08 (CVS) New Comment: While this is a good idea, unfortunately it would introduce API break and likely break many apps that utilize this function. Previous Comments: ------------------------------------------------------------------------ [2007-07-08 11:44:10] zoe at uk dot ibm dot com Description: ------------ The manual states "Returns the value of the configuration option as a string on success, or an empty string on failure" Some options (eg docref_ext, disable_classes) have default values of an empty string, in these cases ini_get() will return an empty string when the function has failed AND when it has succeeded. The problem is in the following code: ZEND_API char *zend_ini_string(char *name, uint name_length, int orig) { zend_ini_entry *ini_entry; TSRMLS_FETCH(); if (zend_hash_find(EG(ini_directives), name, name_length, (void **) &ini_entry)==SUCCESS) { if (orig && ini_entry->modified) { return ini_entry->orig_value; } else { return ini_entry->value; } } return ""; } Reproduce code: --------------- Here is a test that will always pass even when ini_get fails. --TEST-- ini_get returns value of the configuration option as a string on success, empty string on failure --FILE-- <?php var_dump(ini_get("disable_classes")); ?> --EXPECT-- string(0) "" Expected result: ---------------- I would like to be able to see a failure - if ini_get() fails. For example ini_get() could return FALSE on failure (as ini_set() does), if there are no configuration options that have a default value of FALSE. Actual result: -------------- Always a null string. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41922&edit=1
