If string contains month name then convert to number

Question

I have a string $str that contains various date formats (I don't really have control of that!), is it possible to change any month names to numbers?

These are some of the formats coming out:

• 2020-09-14
• 14-feb-2018
• 14-march-2018

Would it then be possible to change all the date formats to the first example?

Answer 1

Yah by this

$new_date = date('Y-m-d',strtotime($old_date));

Eg.

$new_date1 = date('Y-m-d',strtotime('14-feb-2018'));
$new_date2 = date('Y-m-d',strtotime('14-march-2018'));

Answer 2

Try this:

function convertMonthToInt( $date ) {

    $date_bits = explode( "-", $date );

    $months = array(

        "january" => 1,

        //etc etc

    );

    if( is_string( $date_bits[ 1 ] ) !== true ) {

        return $date_bits[ 1 ];

    }

    return $months[ strtolower( $date_bits[ 1 ] ) ];

};

convertMonthToInt( "14-march-2018" );
