"PHP" Print Log method

I am using the Medoo database framework, directly add log to the database, use the need to import the Medoo file.

log.php

<?PHPrequire(‘.. /dao/medoo.php ');functionLogi ($tag,$message) {input ("I",$tag,$message);}functionLogE ($tag,$message) {input ("E",$tag,$message);}functionLOGW ($tag,$message) {input ("W",$tag,$message);}functionLOGD ($tag,$message) {input ("D",$tag,$message);}functionInput$type,$tag,$message) {    $db=NewMedoo (NULL); $db->insert ("En_log",Array (    "L_ID" = uuid (), "l_type" =$type, "l_tag" =$tag, "l_msg" =$message));}/** * Generate UUID*/functionUuid$prefix= ' '){    $chars=MD5(uniqid(Mt_rand(),true)); $uuid=substr($chars, 0,8). ‘-‘; $uuid.=substr($chars, 8,4). ‘-‘; $uuid.=substr($chars, 12,4). ‘-‘; $uuid.=substr($chars, 16,4). ‘-‘; $uuid.=substr($chars, 20,12); return $prefix.$uuid;}?>

Here is the MySQL database structure, I use the UUID to make table primary key

CREATE TABLE ' en_log ' (  ' l_id ' char (null,  nullDEFAULT Current_ TIMESTAMP on UPDATE current_timestamp,  ' L_type ' enum (NULL,  ' L_tag ' char (  NULL,null,  KEY  (' l_id ') ENGINE     DEFAULT Charset=utf8;

I know the PHP print log certainly has a better way to put it.
