I ran the example file, I tryed it with my own dbf/dbt-file and always got this Message: Fatal error: Call to undefined function array_column() in D:\laragon\www\dbasetosql\dbasetosql.class.php on line 181
What did I wrong? This is just the very Class I need. Thank you for your programming.

Hi.
You didn't do anything wrong.Simply your PHP version is too old and don't have the array_column function implemented yet.

But you can avoid this by creating a file with the following content and then include at the top of the package file:

if (!function_exists('array_column')) {
/**
* Returns the values from a single column of the input array, identified by
* the $columnKey.
*
* Optionally, you may provide an $indexKey to index the values in the returned
* array by the values from the $indexKey column in the input array.
*
* @param array $input A multi-dimensional array (record set) from which to pull
* a column of values.
* @param mixed $columnKey The column of values to return. This value may be the
* integer key of the column you wish to retrieve, or it
* may be the string key name for an associative array.
* @param mixed $indexKey (Optional.) The column to use as the index/keys for
* the returned array. This value may be the integer key
* of the column, or it may be the string key name.
* @return array

Yes, in PHP 7 (and also with your remedy) the example file works.

In my Dbase files I have lot of MEMO-fields (dbase IV) and, until now, the output.sql-file did not run.
MEMO and DATE do not convert correctly. Maybe I use the wrong codepage.

Hi

Could you please copy and paste a part of the dump file here.This way i can see the problem and make a diagnostic... thanks.
when you say it didn't run what are you really talking about? the conversion or the importation in mySql?
