Install parsekit Extension

Http://pecl.php.net/package/parsekit

Download the latest

# Wget http://pecl.php.net/get/parsekit-1.3.0.tgz

Installation Process omitted

Can refer to my write http://blog.csdn.net/21aspnet/article/details/7035392 installation apc extension is the same principle

Automatic Installation is very convenient.

Installation:

#/Usr/local/php/bin/pecl install parsekit

Configuration:

Php. ini plus extension = parsekit. so

Restart:

#/Usr/local/apache2/bin/apachectl restart

Test:

#/Usr/local/php/bin/php-r "var_dump (parsekit_compile_string ('print 1 + 1 ;'));"

Output:

Summary:Two methods 1. To view the opcode of a single php statement

#/Usr/local/php/bin/php-r "var_dump (parsekit_compile_string ('print 1 + 1 ;'));"

Reference http://www.php.net/manual/zh/function.parsekit-compile-string.php

2. If you want to view the opcode of a PHP file under the website

Reference http://www.php.net/manual/zh/function.parsekit-compile-file.php

#/Usr/local/php/bin/php-r "var_dump (parsekit_compile_file ('/var/www/tb. php '));"

3. To view the opcode of a function

Reference http://www.php.net/manual/zh/function.parsekit-func-arginfo.php

function foo($bar, stdClass $baz, &$bomb, $bling = false) {
}

var_dump(parsekit_func_arginfo('foo'));
?>
