I want to take an action ONLY if ALL of the following conditions are ALL true simultaneously.
Condition 1 - The first 2 characters of field A are alphabetic. (AA to ZZ).
Condition 2 - The third and fourth character of field A are numeric (00 to 99).
Condition 3 - The fifth and sixth characters of field A are alphabetic. (AA to ZZ).
Condition 4 - The length of field B is at least 2 characters long.
Suggestions welcome please. Using an old version of PHP and really don’t want to upgrade.
