P4PHP Classes

The P4 module consists of several public classes:

P4
P4_Exception

The following tables provide more details about each public class.

P4

Helix Core Server client class. Handles connection and interaction with the Helix Core Server. There is one instance of each connection.

The following table lists properties of the class P4 in P4PHP. The properties are readable and writable unless indicated otherwise. The properties can be strings, arrays, or integers.

`cwd`	Current working directory.
`errors`	A read-only array containing the error messages received during execution of the last command.
`exception_level`	The exception level of the P4 instance. Values can be: `0` : no exceptions are raised `1` : only errors are raised as exceptions `2` : warnings are also raised as exceptions The default value is 2.
`expand_sequences`	Control whether keys with trailing numbers are expanded into arrays; by default, true, for backward-compatibility.

`server_level`	Returns the current Helix Core Server level. This property is read only.
`streams`	Enable or disable support for streams.
`tagged`	To disable tagged output for the following commands, set the value to 0 or False. By default, tagged output is enabled.
`ticket_file`	`P4TICKETS`, the ticket file location used.
`user`	`P4USER`, the user under which the connection is run.
`version`	The version of the script.
`warnings`	A read-only array containing the warning messages received during execution of the last command.

The following table lists all public methods of the class P4.

Method	Description
`connect()`	Connects to the Helix Core Server.
`connected()`	Returns `True` if connected and the connection is alive, otherwise `False`.
`delete_<spectype>()`	Deletes the spec <spectype>. Equivalent to the command: P4::run( "<spectype>", "-d" );
`disconnect()`	Disconnects from the Helix Core Server.
`env()`	Get the value of a Helix Core Server environment variable, taking into account `P4CONFIG` files and (on Windows or macOS) the registry or user preferences.
`identify()`	Returns a string identifying the P4PHP module. (This method is static.)
`fetch_<spectype>()`	Fetches the spec <spectype>. Equivalent to the command: P4::run( "<spectype>", "-o" );
`format_<spectype>()`	Converts the spec <spectype> into a string.
`parse_<spectype>()`	Parses a string representation of the spec <spectype> and returns an array.
`run()`	Runs a command on the server. Needs to be connected, or an exception is raised.
`run_cmd()`	Runs the command cmd. Equivalent to: P4::run( "cmd" );
`run_filelog()`	This command returns an array of `P4_DepotFile` objects. Specialization for the `run()` command.
`run_login()`	Logs in using the specified password or ticket.
`run_password()`	Convenience method: updates the password. Takes two arguments: oldpassword, newpassword.
`run_resolve()`	Interface to `p4 resolve`.
`run_submit()`	Convenience method for submitting changelists. When invoked with a change spec, it submits the spec. Equivalent to: p4::input = myspec; p4::run( "submit", "-i" );
`save_<spectype>()`	Saves the spec <spectype>. Equivalent to the command: P4::run( "<spectype>", "-i" );

P4_Exception

Property	Description
`depotFile`	Name of the depot file
`revisions`	Array of Revision objects.

P4_Revision

Container class containing one revision of a P4_DepotFile object.

Property	Description
`action`	Action that created the revision.
`change`	Changelist number.
`client`	Client workspace used to create this revision.
`desc`	Short changelist description.
`depotFile`	The name of the file in the depot.
`digest`	MD5 digest of the revision.
`fileSize`	File size of this revision.
`integrations`	Array of `P4_Integration` objects.
`rev`	Revision.
`time`	Timestamp.
`type`	File type.
`user`	User that created this revision.

P4_Integration

Container class containing one integration for a P4_Revision object.

Property	Description
`how`	Integration method (merge/branch/copy/ignored).
`file`	Integrated file.
