Question

In my php script I want to check if a structure of database table has changed. The DESCRIBE TABLE wont provide enough informations, because it ignores the foreign keys. The SHOW CREATE TABLE is too much, because auto incremental value also appears here.

Answer 1

The SHOW CREATE TABLE is too much, because auto incremental value
also appears here.

Just filter out the auto incremental value with a regexp.

preg_replace('/ AUTO_INCREMENT=[0-9]+ /', ' ', $sql);
