(PECL)
bcompiler_write_exe_footer -- Writes the start pos, and sig to the end of a exe type file
Beschreibung
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.
Parameter Liste
filehandle
A file handle as returned by fopen().
startpos
The file position at which the Bytecodes start, and can be obtained
using ftell().
Rückgabewerte
Gibt bei Erfolg TRUE zurück, im Fehlerfall FALSE.
