<?

function HeighPHPcode(＄Heightstring){

do{

＄z=0;

if(preg_match('/<phpcode>(.*)</phpcode>/sU',＄Heightstring,＄reg)) {

＄z=1;

＄code='';

ob_start();

highlight_string(＄reg[1]);

＄code = ob_get_contents();

ob_end_clean();

＄reg[1] = addslashes(＄reg[1]);

＄Heightstring=preg_replace("/<phpcode>(.*)</phpcode>/sU","＄code",＄Heightstring,1);

}

}while(＄z);

return ＄Heightstring;

}
