bcompiler_write_exe_footer

(PECL bcompiler >= 0.4)

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 wird FALSE zurückgegeben.

Beispiele

Beispiel #1 bcompiler_write_exe_footer() example

<?php

/* creating the output file (example.exe) */
$fh = fopen("example.exe", "w");

/* 1) writing a stub (phpe.exe) */
$size = filesize("phpe.exe");
$fr = fopen("phpe.exe", "r");
fwrite($fh, fread($fr, $size), $size);
$startpos = ftell($fh);

/* 2) writing bytecodes */
bcompiler_write_header($fh);
bcompiler_write_class($fh, "myclass");
bcompiler_write_function($fh, "main");
bcompiler_write_footer($fh);

/* 3) writing EXE footer */
bcompiler_write_exe_footer($fh, $startpos);

/* closing the output file */
fclose($fh);
?>
