Oi gente, pensando em criar algumas funções do zero, resolvi recriar funções nativas utilizando meus próprios métodos. Primeiramente vamos começar com uma cópia fiel de ord

Para quem não sabe, em PHP a função ord é responsável por retornar o valor decimal de um caractere

Segue o trecho de código:

function ord($c) {
$ords = array('\0' =>0,' ' =>1,' ' =>2,' ' =>3,' ' =>4,' ' =>5,' ' =>6,' ' =>7,' ' =>8,' ' =>9,' ' =>10,' ' =>11,' ' =>12,' ' =>13,' ' =>14,' ' =>15,' ' =>16,' ' =>17,' ' =>18,' ' =>19,' ' =>20,' ' =>21,' ' =>22,' ' =>23,' ' =>24,' ' =>25,' ' =>26,' ' =>27,' ' =>32,'!' =>33,'\"' =>34,'#' =>35,'$' =>36,'%' =>37,'&' =>38,"'" =>39,'(' =>40,')' =>41,'*' =>42,'+' =>43,',' =>44,'-' =>45,'.' =>46,'/' =>47,'0' =>48,'1' =>49,'2' =>50,'3' =>51,'4' =>52,'5' =>53,'6' =>54,'7' =>55,'8' =>56,'9' =>57,':' =>58,';' =>59,'<' =>60,'=' =>61,'>' =>62,'?' =>63,'@' =>64,'A' =>65,'B' =>66,'C' =>67,'D' =>68,'E' =>69,'F' =>70,'G' =>71,'H' =>72,'I' =>73,'J' =>74,'K' =>75,'L' =>76,'M' =>77,'N' =>78,'O' =>79,'P' =>80,'Q' =>81,'R' =>82,'S' =>83,'T' =>84,'U' =>85,'V' =>86,'W' =>87,'X' =>88,'Y' =>89,'Z' =>90,'[' =>91,'\\' =>92,']' =>93,'^' =>94,'_' =>95,'`' =>96,'a' =>97,'b' =>98,'c' =>99,'d' =>100,'e' =>101,'f' =>102,'g' =>103,'h' =>104,'i' =>105,'j' =>106,'k' =>107,'l' =>108,'m' =>109,'n' =>110,'o' =>111,'p' =>112,'q' =>113,'r' =>114,'s' =>115,'t' =>116,'u' =>117,'v' =>118,'w' =>119,'x' =>120,'y' =>121,'z' =>122,'{' =>123,'|' =>124,'}' =>125,'~' =>126,'' =>127,'€' =>128,'' =>129,'‚' =>130,'ƒ' =>131,'„' =>132,'…' =>133,'†' =>134,'‡' =>135,'ˆ' =>136,'‰' =>137,'Š' =>138,'‹' =>139,'Œ' =>140,'' =>141,'Ž' =>142,'' =>143,'' =>144,'‘' =>145,'’' =>146,'“' =>147,'”' =>148,'•' =>149,'–' =>150,'—' =>151,'˜' =>152,'™' =>153,'š' =>154,'›' =>155,'œ' =>156,'' =>157,'ž' =>158,'Ÿ' =>159,' ' =>160,'¡' =>161,'¢' =>162,'£' =>163,'¤' =>164,'¥' =>165,'¦' =>166,'§' =>167,'¨' =>168,'©' =>169,'ª' =>170,'«' =>171,'¬' =>172,'-' =>173,'®' =>174,'¯' =>175,'°' =>176,'±' =>177,'²' =>178,'³' =>179,'´' =>180,'µ' =>181,'¶' =>182,'·' =>183,'¸' =>184,'¹' =>185,'º' =>186,'»' =>187,'¼' =>188,'½' =>189,'¾' =>190,'¿' =>191,'À' =>192,'Á' =>193,'Â' =>194,'Ã' =>195,'Ä' =>196,'Å' =>197,'Æ' =>198,'Ç' =>199,'È' =>200,'É' =>201,'Ê' =>202,'Ë' =>203,'Ì' =>204,'Í' =>205,'Î' =>206,'Ï' =>207,'Ð' =>208,'Ñ' =>209,'Ò' =>210,'Ó' =>211,'Ô' =>212,'Õ' =>213,'Ö' =>214,'×' =>215,'Ø' =>216,'Ù' =>217,'Ú' =>218,'Û' =>219,'Ü' =>220,'Ý' =>221,'Þ' =>222,'ß' =>223,'à' =>224,'á' =>225,'â' =>226,'ã' =>227,'ä' =>228,'å' =>229,'æ' =>230,'ç' =>231,'è' =>232,'é' =>233,'ê' =>234,'ë' =>235,'ì' =>236,'í' =>237,'î' =>238,'ï' =>239,'ð' =>240,'ñ' =>241,'ò' =>242,'ó' =>243,'ô' =>244,'õ' =>245,'ö' =>246,'÷' =>247,'ø' =>248,'ù' =>249,'ú' =>250,'û' =>251,'ü' =>252,'ý' =>253,'þ' =>254);
return $ords[$c];
}

Espero que tenham gostado, é bom para estudos. Vou postar outras funções que recriei da mesma forma.

Abraço
