bcompiler_write_function
BCOMPILER_WRITE_FUNCTION(3) 1 BCOMPILER_WRITE_FUNCTION(3)
bcompiler_write_function - Writes a defined function as bytecodes
SYNOPSIS
bool bcompiler_write_function (resource $filehandle, string $functionName)
DESCRIPTION
Reads the bytecodes from PHP for an existing function, and writes them to the open file handle. Order is not important, (eg. if function b
uses function a, and you compile it like the example below, it will work perfectly OK).
PARAMETERS
o $filehandle
- A file handle as returned by fopen(3).
o $functionName
- The function name, as a string.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
bcompiler_write_function(3) example
<?php
$fh = fopen("/tmp/example","w");
bcompiler_write_header($fh);
bcompiler_write_function($fh,"my_function_a");
bcompiler_write_function($fh,"my_function_b");
bcompiler_write_footer($fh);
fclose($fh);
?>
