Need understanding of this bit of code

Posted on 16th Feb 2014 by admin

Code: <?php
// WHERE clause filters
$arrSQLFilters = array();

// whether or not zip codes table needs to be included
$boolIncludeZipCodes = false;

// Zipcode filter
if(!empty($strZipCode)) {
$boolIncludeZipCodes = true;

$arrSQLFilters[] = sprintf(
"z.zip LIKE '%s'"
,"%$strZipCode%"
);
}

// State filter
if(!empty($strState)) {
$boolIncludeZipCodes = true;

$arrSQLFilters[] = sprintf(
"z.state = '%s'"
,$strState
);
}

// Restaurants name filter
if(!empty($strName)) {
$arrSQLFilters[] = sprintf(
"r.restaurantname LIKE '%s'"
,"%$strName%"
);
}?>
