Zend Debugger - Configuration Directives

Configuration Directives Summary

Directive	Type	Modification Scope	Description
zend_debugger.allow_hosts	string	PHP_INI_SYSTEM	Specifies the hosts that are allowed to connect (hostmask list) with Zend Debugger when running a remote debug session with Zend Studio
zend_debugger.deny_hosts	string	PHP_INI_SYSTEM	Specifies the hosts that are not allowed to connect (hostmask list) with the Zend Debugger when running a remote debug session with Zend Studio
zend_debugger.allow_tunnel	string	PHP_INI_SYSTEM	A list of hosts (hostmask list) that can use the machine on which Zend Server is installed to create a communication tunnel for remote debgging with Zend Studio. This is done to solve firewall connectivity limitations
zend_debugger.max_msg_size	integer	PHP_INI_SYSTEM	The maximum message size accepted by the Zend Debugger for protocol network messages
zend_debugger.httpd_uid	integer	PHP_INI_SYSTEM	The user ID of the httpd process that runs the Zend Debugger (only for tunneling)
zend_debugger.tunnel_min_port	integer	PHP_INI_SYSTEM	A range of ports that the communication tunnel can use. This defines the minimum value for the range
zend_debugger.tunnel_max_port	integer	PHP_INI_SYSTEM	A range of ports that the communication tunnel can use. This defines the maximum value for the range
zend_debugger.expose_remotely	integer	PHP_INI_SYSTEM	Define which clients know that the Zend Debugger is installed:<br> 0 - Never. The presence of the Zend Debugger is not detected by other clients <br> 1 - Always. All clients can detect the Zend Debugger <br> 2 - Allowed Hosts. Only clients listed in zend_debugger.allow_hosts can detect the Zend Debugger<br> Any other value makes the Zend Debugger undetectable (same as "Never")
zend_debugger.passive_mode_timeout	integer	PHP_INI_ALL	The Debugger's timeout period (in seconds) to wait for a response from the client (Zend Studio)
zend_debugger.xdebug_compatible_coverage	boolean	PHP_INI_ALL	Directive in order to mock up xdebug coverage
zend_debugger.use_fast_timestamp	boolean	PHP_INI_ALL	Enables fast time sampling which is dependent on CPU cycles and frequency, otherwise, the directive uses operating system timing (which may be less accurate)
