Using assert_options() you may set the various assert() control options or just query their current settings.
Table 1. Assert Options
| option | ini-parameter | default | description |
|---|---|---|---|
| ASSERT_ACTIVE | assert.active | 1 | enable assert() evaluation |
| ASSERT_WARNING | assert.warning | 1 | issue a PHP warning for each failed assertion |
| ASSERT_BAIL | assert.bail | 0 | terminate execution on failed assertions |
| ASSERT_QUIET_EVAL | assert.quiet_eval | 0 | disable error_reporting during assertion expression evaluation |
| ASSERT_CALLBACK | assert.callback | (NULL) | user function to call on failed assertions |
assert_options() will return the original setting of any option or FALSE on errors.
