run_composer
run_composer (composer, arr)
The run_composer function runs the publishing process associated with composer, using the parameters in the associative array arr.
The composer parameter is a composer handle generated by the get_composer function. The arr parameter specifies an associative array of parameter values. Both parameters are defined in a composer’s CCF file.
The function returns 0 if an error occurs, or 1 if the operation was successful.

Calling this function requires parsing the CCF file, unless the file has been cached. Subsequent changes to the CCF file will not be seen unless you flush the composer using the flush_composer function.
