英語の文字列を単純に圧縮するための PHP コード

//replacement 以前のバージョンからの暗号化された置換
function compress_func($match) {return strlen($match[0]).$match[0]{0 } ;}
function uncompress_func($match) {return str_repeat($match[2], $match[1]);}
function compress($str) {
 $i = 0;
 $pattern = array(); while(isset($replacement{$i})) array_push($pattern, "/".$replacement{$i++}."{2,}/");
 return preg_replace_callback($pattern, "compress_func", $ str );
 }
function uncompress($str) {
 return preg_replace_callback("/(d+)(w)/", "uncompress_func", $str);
?> ;

 str_out = ""
 str_len = length(str); ;
 l = 1;
 for(i =1; i  if(substr(str, i, 1) == s) l++;
 if(s != "" ) {
 if(l > 1) str_out=str_out""l
 str_out=str_out""s; }
 s = substr(str, i, 1)
 }
 }
 return str_out; ;
}
関数 uncompress(str, _ARGVEND_, str_out, str_len, i, c) {
 str_out = "";
 str_len = length(str);
 c = 0;
 while(substr(str, i, 1)~/[0-9]/) {
 c = c*10+substr(str, i, 1) }
 if( c  while(c--) str_out = str_out""substr(str, i, 1)
 str_out をコピーします
