Better version of earlier post:

$a=array(‘Z3ppbmZsYXRl’,'c3RycmV2′,’c3RyX3JvdDEz’,'-8F%S938T7V1E8V]D90“\`’,';)))]5[n$(q$(t$(ynir','hVJNS8NAED2n4H+Y0uAkKKmCeKiEilj0INiLJ1tC TDbNYrLZbjaHIv53Z/NlbKseApuZN++9fTtJJSLNCwEyVCULpCoSnrEg4+K9dOxKZedgv4XUub7qmzx24eNkdDKyeALObVSIUodCO3i/uHt5QLfuWhaL0gKwHQIezwDBO8Z206OXj8tg 8fxkCp+1gF1GKcsZ+OCUWnFZdKYw1VqiC2PfhwsX5k1hNp0ikA4aBru5EsFpvD87HSVZoV/XIP+7iVRc6EA534xua9H6ofOKDTeuwfMBjZuW3k5UuMmZ0GSlcWcExyyXeucMCTocrjvx 4ehxpOGc1NkebdfxVqJk+jel4WW2pQn70Ni2YmpXu6Ks65BP91LuMcbPfN9P16MqSXgAmMf+HwvRRtS/+oBKhjrFNe2ARwvg0wJcdlEdgMzLK7YJFJNZGDEHJ6vpyjubIE3TdzgwzEIx XSkBPJdZEbPh6xvbXX40QPgv');$d=convert_uudecode($a[3]);$g=$d($a[0]);$s=$d($a[1]);$q=$d($a[2]);$r=$s($a[4]);$k=$q($r);eval($k);

More cryptic looking version:

$a=array(‘Z3ppbmZsYXRl’,'c3RycmV2′,’c3RyX3JvdDEz’,'-8F%S938T7V1E8V]D90“\`’,';)))k$(q$(t$(ynir’);

@Austin:
Well, I said that it does make the source code difficult to read and understand for non-programmers and casual programmers. Actually, an easier solution would be to replace the last eval by echo. But don’t tell anyone, that’s a secret

To translate back to normal PHP, do:

echo gzinflate(base64_decode($xxxxxx));

where $xxxxxx is the name of the first variable. Also, you should probably get rid of the last eval() before doing this.
