goto


php128 apg

Can be used to jump to another section in the program.

Available since PHP 5.3.0.


The goto operator is used, at run-time, to jump to an specified point of the program.

This point is specified by a label followed by a semicolon, just after to the operator goto.

The targeted label has the same name, however, followed by a colon.

       statement


where,

target = the target point specified by a label

statement = code to be executed
