PHP Deobfuscation

**Executive Summary:** The report is a short technical walkthrough for deobfuscating heavily obfuscated PHP code: it outlines common obfuscation methods (base64, hex/octal strings, variable function assignments, eval), explains how to compile and use the evalhook extension on CentOS5, and mentions a Perl helper script to convert encoded strings to ASCII. The content is a how-to for analysts, not a description of a specific security incident.
