Background/Need -================== - -Many internal function of PHP will reject parameters because of their -type (the array and variable function come to mind). For userland -this is not an easy task as there is no uniform way to do it. An -addition to the engine for requiring loose types would allow -delevopers to know that the data passed to their functions is of the -correct type and reduce the need for duplicating the same code in -every function to check for the type of data. - - -2. Overview -=========== - -Loose typing mostly means evaluating the contents of the variable and -not the type of the variable itself. The requirements for this would -and should work much like several of the is_* functions do now. - -The typing of parameters would be optional and those not typed would -simply continue to be treated as they are now. - -3. Functionality -================ - -3.1. Allowed Types -================== - -Only loose types should be needed to ensure the data is usable by the -function. Duplicating the functionallity of is_scalar, is_resource, -is_array and is_object should give developers all the information they -need to use a variable correctly. - -3.2. Syntax -=========== - -The current function syntax should be expanded to allow typing of -variables inline in a C style. - -function foo ($var){ -} - -could be changed to require an array such as: - -function foo (array $var){ -} - -3.3. Errors -=========== - -Mis-matches in type should be reported as fatal errors and should halt -the execution of a script as that function can not be run and code -following could not reliably run. - - -4. Compatibility Notes -====================== - -Old code that does not take advantage of this will run without -modifications. - - - - |
