Limit Process

This example shows the usage of Limit process

nameincome
John $50,000
Marry $60,000
Peter $100,000
Donald $80,000

->pipe(new Limit(
    array(2,0)
))
nameincome
John $50,000
Marry $60,000

The example demonstrates usage of Limit process. The filter process is used to limit data. In above example, the process will return 2 rows and starting at row 0. The format is

->pipe(new Limit(array($size,$offset)))

Short form

Most of the case we return the first number of rows so limit in above example is equivalent to:

->pipe(new Limit(
    array(2)
))
