Zend Debugger - Configuration Directives

This topic lists all the configuration directives for Zend Debugger.

Configuration Directives Summary

The table below is a summary of all the Zend Debugger configuration directives, and displays the directive name, its default value, and a description:

Directive	Default Value	Description
zend_debugger.allow_hosts	127.0.0.0/8,10.0.0.0/8,192.168.0.0/16,172.16.0.0/12	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		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		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	2097152	The maximum message size accepted by the Zend Debugger for protocol network messages
zend_debugger.httpd_uid	-1	The user ID of the httpd process that runs the Zend Debugger (only for tunneling)
zend_debugger.tunnel_min_port	1024	A range of ports that the communication tunnel can use. This defines the minimum value for the range
zend_debugger.tunnel_max_port	65535	A range of ports that the communication tunnel can use. This defines the maximum value for the range
zend_debugger.expose_remotely	2	Define whether to expose the presence of the Zend Debugger to remote clients
zend_debugger.passive_mode_timeout	20	The Debugger's timeout period (in seconds) to wait for a response from the client (Zend Studio)
zend_debugger.xdebug_compatible_coverage	0	Directive in order to mock up xdebug coverage
zend_debugger.use_fast_timestamp	1	Enables fast time sampling which is dependent on CPU cycles and frequency, otherwise, the directive uses operating system timing (which may be less accurate)
zend_debugger.enable_coverage	0	Enable code-coverage feature, should only be true on local debugger
