Hi!
I am wondering what the opcode EXT_FCALL_BEGIN and EXT_FCALL_END is used for?
When php is in "extended opcode" mode (usually used by debuggers) these opcodes are generated by the compiler before entering and after exiting function calls (so that the debugger could do "step into" and "step over"). They are not used in non-debugging context. -- Stanislav Malyshev, Zend Software Architect stas@zend.com http://www.zend.com/ (408)253-8829 MSN: stas@zend.com
