I have values like this in mysql.

I need wholesaletl name based on wholesaletlcontact.

Example: when I have value ajin3 then i need the value 1234587452

Answer 1

Get the field values from db. Explode them to an array.

$myString = "ajin1,ajin3,ajin2";
$myArray = explode(',', $myString);
print_r($myArray);

Do the same for the other field values.

Output will be: Array ( [0] => ajin1 [1] => ajin3 [2] => ajin2 )

Then get the id for a specific value:

$key = array_search('ajin3', $myArray);

And that Id will correspond to the required value in the other array.

$wholesaletl=explode(",",$record->wholesaletl); $wholesaletlcontact=explode(",",$record->wholesaletlcontact); $wholesaletlcontact_arr=array(); if(count($wholesaletl) > 0){ foreach($wholesaletl as $key => $value){ $wholesaletlcontact_arr[$value]=$wholesaletlcontact[$key]; } echo $wholesaletlcontact_arr["ajin3"];

If you don't have a choice about using the csv files or if you don't feel that the drawbacks matter, the following code should help you with accessing the information:

function get_contact_from_name($name, &$name_array, &$contact_array) {
    $name_index = array_search($name, $name_array);

    // Name is not in csv list
    if ($name_index === false) {
        echo "Name does not exist: $name<br />";
        return null;
    }

    // There is no contact in the corresponding postion
    if (!isset($contact_array[$name_index])) {
        echo "Contact does not exist at position: $name_index<br />";
        return null;
    }

    return $contact_array[$name_index];
}

$names = 'bill,george,sophia,marge';

$wholesaleltnames = str_getcsv("bill,george,sophia", ",");
$wholesaleltcontacts = str_getcsv("123,456", ",");

foreach (explode(',', $names) as $name) {
    $c = get_contact_from_name($name, $wholesaleltnames, $wholesaleltcontacts);
    if ($c) {
        echo "Contact: $name, $c<br />";
    }
}

You will need to modify it to fit your needs. For example, it would need to be updated to use the row returned from mysql and to handle errors properly.
