I want to hook before execution / or replace standart core functions, for example i im going to prevent both include and require accesa to any scripts. Is any way to make it without any extra .dll's? Or another case is_array($myarr); i would be to hook at array($myarr) === $myarr; (looks like it is faster) to avoid creating extra classes and functions.
Ps and one more question : how to prevent all php execution after some moment? I have html templates with php parts <?=$myvar?> i want to prevent short sintax and execution at all when my script ends work, what i have to try?
About hooks to standart functions: there is no way to do that without external modules. APD PECL module
will do the job.
rename_function('require', 'internal_require'); // saving reference to original function
override_function('require', '$filename',
'print "require called"; internal_require($filename);');
Second question is not very clear. Do you want to hook on standart is_array function, to array() lexical construct or (array) type casting?
About stopping php interpretation: have a look at __halt_compiler function. But keep in mind that succeeding blocks of php will be just embedded in HTML (thus visible to everybody).
If you want to disable functions, you can use safe mode, but it is deprecated and not recommended. And as madfriend says, __halt_compiler just sends everything below it as text. Bear in mind that it can only be called from the outermost scope - I.e. not inside curly braces (if, loops, functions etc.)
