bcompiler_write_exe_footer
(PECL bcompiler:0.4-0.8)
bcompiler_write_exe_footer — Writes the start pos, and sig to the end of a exe type file
说明
bool bcompiler_write_exe_footer
( resource $filehandle
, int $startpos
)
An EXE (or self executable) file consists of 3 parts:
- The stub (executable code, e.g. a compiled C program) that loads PHP interpreter, bcompiler extension, stored Bytecodes and initiates a call for the specified function (e.g. main) or class method (e.g. main::main)
- The Bytecodes (uncompressed only for the moment)
- The bcompiler EXE footer
To obtain a suitable stub you can compile php_embed-based stub phpe.c located in the examples/embed directory on bcompiler's CVS.
参数
