Convert state to state abbreviation

[rondog]

I have a database with like 3000 entries that all have the full state name like "California"...I need to change all these to the abbreviated version like "CA".

 

Can someone help me come up with a script to just run once and have it update all the entries?

 

I already have an array of state info with both full name and abbreviation:

$states_arr  = array('AL'=>"Alabama",'AK'=>"Alaska",'AZ'=>"Arizona",'AR'=>"Arkansas",'CA'=>"California",'CO'=>"Colorado",'CT'=>"Connecticut",'DE'=>"Delaware",'FL'=>"Florida",'GA'=>"Georgia",'HI'=>"Hawaii",'ID'=>"Idaho",'IL'=>"Illinois", 'IN'=>"Indiana", 'IA'=>"Iowa",  'KS'=>"Kansas",'KY'=>"Kentucky",'LA'=>"Louisiana",'ME'=>"Maine",'MD'=>"Maryland", 'MA'=>"Massachusetts",'MI'=>"Michigan",'MN'=>"Minnesota",'MS'=>"Mississippi",'MO'=>"Missouri",'MT'=>"Montana",'NE'=>"Nebraska",'NV'=>"Nevada",'NH'=>"New Hampshire",'NJ'=>"New Jersey",'NM'=>"New Mexico",'NY'=>"New York",'NC'=>"North Carolina",'ND'=>"North Dakota",'OH'=>"Ohio",'OK'=>"Oklahoma", 'OR'=>"Oregon",'PA'=>"Pennsylvania",'RI'=>"Rhode Island",'SC'=>"South Carolina",'SD'=>"South Dakota",'TN'=>"Tennessee",'TX'=>"Texas",'UT'=>"Utah",'VT'=>"Vermont",'VA'=>"Virginia",'WA'=>"Washington",'DC'=>"Washington D.C.",'WV'=>"West Virginia",'WI'=>"Wisconsin",'WY'=>"Wyoming");

Make another array with the state names as the keys and the abbreviations as the values:

<?php
$states_abbr = array();
foreach ($states_arr as $abbr => $state) {
    $states_abbr[$state] = $abbr
}
?>

The simply retrieve each record  and use the $states_abbr array to get the correct abbreviation and update the record.

Update the table:

 

$case = '';
foreach ($states_arr as $country_code => $country_name) {
  $case .= "WHEN '$country_name' THEN '$country_code' ";
}

$query = "UPDATE table SET country_code = (CASE country_name $case END)";
echo $query;//check if query was properly constructed

 

Or use ken's solution to map states to their abbreviations at run-time.

I definitely have to learn about the CASE in MySQL...

 

Thanks.

I would have suggested.

 

$search_term = 'California';
$abbr = array_keys($states_arr,$search_term);
echo $abbr[0];

 

This would run at runtime, I don't know if I would change all of those columns.  If I wanted to input them into the Base, I would add a column.
