An EXE (or self executable) file consists of 3 parts:
|
|
<simplelist>
|
|
<member>
|
|
The <literal>stub</literal> (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. <literal>main::main</literal>)
|
|
</member>
|
|
<member>The Bytecodes (uncompressed only for the moment)</member>
|
|
<member>The bcompiler EXE footer</member>
|
|
</simplelist>
|
|
</para>
|
|
<para>
|
|
To obtain a suitable stub you can compile php_embed-based stub <filename>phpe.c</filename>
|
|
located in the <filename>examples/embed</filename> directory on bcompiler's CVS.
