When starting the library PHP will be set to a silent and more sensitive mode.
The PHP environment will be set as follows:
- strict mode
- E_NOTICEs are turned to E_ERRORs and script will be halted
- E_WARNINGs will be turned to E_ERRORs and script will be halted
- mute mode
- display errors will be deactivated for CLI and SAPI environment
This settings can be easily changed to a less tight handling. See the docs for strict mode and mute mode.
