Question

I am using a db query that takes in a state and city then spits out 10 fields. Currently I can only see those fields by using print_r. I tried a suggestion on the php manual site a for loop to print the fields however I can’t get it to work properly. Here is the code:

    if (!$result) {
        echo 'Could not run query: ' . mysql_error();
        exit;
    }
    if (mysql_num_rows($result) > 0) {
        while ($row = mysql_fetch_assoc($result)) {
            print_r($row)."</p>";
            $arrayLength = count($row);
            for ($i = 0; $i < $arrayLength; $i++){
                echo "arrayName at[" . $i . "] is: [" .$row[$i] . "]<br>\n";
            }
                
                
        }

    }

And this is the result:

Array ( [id] => 1299 [zip_code] => 04011 [city] => Brunswick [county] => Cumberland [state_name] => Maine [state_prefix] => ME [area_code] => 207 [time_zone] => Eastern [lat] => 43.9056 [lon] => -69.9646 ) ....
arrayName at[0] is: []
arrayName at[1] is: []
arrayName at[2] is: []
arrayName at[3] is: []
arrayName at[4] is: []
arrayName at[5] is: []
arrayName at[6] is: []
arrayName at[7] is: []
arrayName at[8] is: []
arrayName at[9] is: []

Any ideas why I am not able to properly print the fields and their values? Also my code fails if the query returns more than one row as the current code doesn’t really accommodate it.

I put $i in the body of the for loop to see if it was working properly. Ideally I would have the field name where $i is and the value to the right of it after the colon.

Answer 1

you are fetching with mysql_fetch_assoc so
change loop into

foreach($row as $key => $value){
echo "Array key : $key = $value <br/>";
}
