Answer 1

Below is the code from which you can get all the four data that you want.
$sql_getnm = "SELECT * FROM util WHERE util_head IN ('wc_email', 'wc_contact_us', 'wc_mobile', 'wc_google_map');";
$result_getnm = $connect->query($sql_getnm);
while($row_getnm = $result_getnm->fetch_array()) {
if($row_getnm['util_head'] == 'wc_email'){
$util_value_email_data = $row_getnm['util_value'];
}
if($row_getnm['util_head'] == 'wc_contact_us'){
$util_value_contact_data = $row_getnm['util_value'];
}
if($row_getnm['util_head'] == 'wc_mobile'){
$util_value_mobile_data = $row_getnm['util_value'];
}
if($row_getnm['util_head'] == 'wc_google_map'){
$util_value_map_data = $row_getnm['util_value'];
}
}

Answer 2

You need to replace * with columns name with comma separation.
$sql_getnm = "SELECT Columname1,Columname2,Columname3,Columname4 FROM util WHERE util_head IN ('wc_email', 'wc_contact_us', 'wc_mobile', 'wc_google_map');";
$result_getnm = $connect->query($sql_getnm);
while($row = mysql_fetch_array($result_getnm, MYSQL_ASSOC)
$util_value_email_data= $row['Columname1'];
$util_value_mobile_data= $row['Columname2'];
$util_value_map_data= $row['Columname3'];
$util_value_data= $row['Columname4'];
