TRACE LONG ON|OFF - Enables/disables method argument and detail debug trace.
TRACE PACKET ON|OFF|<size> - Enables/disables packet trace, limiting the size of the traced object to the specified number of bytes, or 1000 if no size is specified.
TRACE SQL ON|OFF - Enables/disables high level api trace.
TRACE TIMESTAMP ON|OFF - Enables/disables a timestamp prefix on each line that is traced.
TRACE SIZE <size> - Limits the size of the trace file to <size> bytes, at least 8192 bytes are required.

范例

Example#1 Procedural style


<?php

maxdb_debug("trace packet 200");

$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

/* check connection */
if (!$link) {
   printf("Connect failed: %s\n", maxdb_connect_error());
   exit();
}

/* close connection */
maxdb_close($link);
?>

The above example produces no output.
