Workflow: ezcWorkflowNodeVariableSub

[ Tutorial ] [ Class tree ] [ Element index ] [ ChangeLog ] [ Credits ]

Class: ezcWorkflowNodeVariableSub

Subtracts a workflow variable from another variable or a constant value. [source]

An object of the ezcWorkflowNodeVariableSub class subtracts a given operand, either a constant or the value of another workflow variable, from a specifled workflow variable.

This example will subtract the contents of the workflow variable 'wfVar' by five and put the result back in 'wfVar'.

1.   $op = 5;
2.   $sub = new ezcWorkflowNodeVariableSub (
3.            array ( 'name' = > 'wfVar' , 'operand' = > $op )
4.             );

If operand is a string, the value of the workflow variable identified by that string is used.
