Waarschuwing

Deze functie is EXPERIMENTEEL. Dat betekent, dat het gedrag van deze functie, deze functienaam, in concreto ALLES dat hier gedocumenteerd is in een toekomstige uitgave van PHP ZONDER WAARSCHUWING kan veranderen. Wees gewaarschuwd, en gebruik deze functie op eigen risico.

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

The startpos is the file position at which the Bytecodes start, and can be obtained using ftell($fh).

To obtain a suitable stub you can compile php_embed-based stub phpe.c located in the examples/embed directory on bcompiler's CVS.

Voorbeeld 1. bcompiler_write_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);
?>
