The default value (if this function is not called) is "SNMP_VALUE_LIBRARY", which seems to be SNMP's built-in way of printing things.

From "snmp.c":
<code>
static PHP_GINIT_FUNCTION(snmp)
{
    snmp_globals->valueretrieval = SNMP_VALUE_LIBRARY;
}
</code>

A mild description of these is:
SNMP_VALUE_LIBRARY: This is a string similar to:
"INTEGER: 42"

SNMP_VALUE_PLAIN: This is a string similar to:
"42"

SNMP_VALUE_OBJECT: This is a PHP object like:
object(
"type" => SNMP_INTEGER,
"value" => 42,
)
Here, "type" is one of the SNMP_* types that are listed under the "Predefined Constants" page.  In addition, types 128, 129, and 130 are error conditions.

Sample is swow Interface status.
(.iso.org.dod.internet.mgmt.mib-2.
interfaces.ifTable.ifEntry.ifAdminStatus)
Possible values for this request from MIB:
Enum(integer): up (1), down (2), testing (3)

<?php
//snmp_set_quick_print(0);  // is default
$strIP = "10.1.1.1"; $strComm = "public";
$strOID ".1.3.6.1.2.1.2.2.1.7.1";
echo
"\n Default valueretrieval with snmp_set_quick_print(0)";
echo
" snmp_get_valueretrieval = SNMP_VALUE_LIBRARY";
echo
", retrieved value " snmpget($strIP, $strComm, $strOID); 
snmp_set_valueretrieval(SNMP_VALUE_LIBRARY);   
echo
"\n SNMP_VALUE_LIBRARY " . snmp_get_valueretrieval();
echo
", retrieved value " .   snmpget($strIP, $strComm, $strOID); 
snmp_set_valueretrieval(SNMP_VALUE_PLAIN);   
echo
"\n SNMP_VALUE_PLAIN " . snmp_get_valueretrieval();
echo
", retrieved value " snmpget($strIP, $strComm, $strOID); 

snmp_set_quick_print(1);
echo
"\n Default valueretrieval snmp_set_quick_print(0) " ;
snmp_set_valueretrieval(SNMP_VALUE_LIBRARY);   
echo
"\n SNMP_VALUE_LIBRARY " . snmp_get_valueretrieval();
echo
", retrieved value " .   snmpget($strIP, $strComm, $strOID); 
snmp_set_valueretrieval(SNMP_VALUE_PLAIN);   
echo
"\n SNMP_VALUE_PLAIN " . snmp_get_valueretrieval();
echo
", retrieved value " snmpget($strIP, $strComm, $strOID); 
?>

Results:
Default valueretrieval with snmp_set_quick_print(0)
     snmp_get_valueretrieval = SNMP_VALUE_LIBRARY,
retrieved value up(1)
SNMP_VALUE_LIBRARY 0, retrieved value up(1)
SNMP_VALUE_PLAIN 1, retrieved value 1
Default valueretrieval snmp_set_quick_print(0)
SNMP_VALUE_LIBRARY 0, retrieved value up
SNMP_VALUE_PLAIN 1, retrieved value 1

It appears that the possible method constants for this function are:

SNMP_VALUE_LIBRARY
SNMP_VALUE_PLAIN
SNMP_VALUE_OBJECT

If you are harvesting data you probably want SNMP_VALUE_PLAIN.
