注意：在micro主版本号1之前，下面用到的magic可能发生变化。
micro通过特殊的magic来标识INI文件头，通过INI文件头可以实现micro带INI启动。
一个带INI的micro自执行文件的结构：
|--------------------------|---------------------------------------------------------------------------|----------------------|
| micro.sfx ELF/PE header | ini part | php/phar code |
| | | | | |
| micro_get_sfx_filesize() | 4 byte magic | 4 byte sizeof(ini text) | n byte ini text | |
| returns sizeof this part | "\xfd\xf6\x69\xe6" | "\0\0\0\x10"(16 in big endian) | "ini_key=\"value\"" | "<?php things();..." |
|--------------------------|---------------------------------------------------------------------------|----------------------|
^ micro_open_self() will return stream start at here |
fopen functions will create stream start reading at here, code will run from here ^
ini文件头为
struct MICRO_INI_HEADER{
uint32_t magic; // "\xfd\xf6\x69\xe6"
uint32_t size; // in big-endian
}例如：使用以下php代码来生成ini头：
$myini = "
ffi.enable=1
micro.php_binary=cafebabe
"
$f=fopen("myiniheader.bin", "wb");
fwrite($f, "\xfd\xf6\x69\xe6");
fwrite($f, pack("N", strlen($myini)));
fwrite($f, $myini);
fclose($f);然后执行
Windows:
COPY /B micro.sfx + myiniheader.bin + myawesomeapp.phar myawesomeapp.exeUnix:
cat micro.sfx myiniheader.bin myawesomeapp.phar > myawesomeapp
chmod 0755 myawesomeapp来生成带INI设置的micro自执行文件
