-==== hebrevc() function ====+==== pdo_odbc.db2_instance_name php.ini directive ====
  
-The ''hebrevc($str)'' function is equivalent to ''nl2br(hebrev($str))''. This is a case where the explicit version is much clearer than the shortcut. Combined with the fact that ''hebrevc()'' is a rather niche function, a deprecation is suggested.+As of PHP 5.1.1 ''pdo_odbc.db2_instance_name'' was marked as deprecated in the manual, leaning towards the removal in a future version of PHP. This ini directive modifies the DB2INSTANCE environment variable for non Windows based operating systems, allowing pdo_odbc to make cataloged connections to a DB2 database.
  
-Proposed action: Mark ''hebrevc()'' as deprecated, so that a deprecation warning is thrown on each call. In PHP 8 the function will be removed.+The side effect here is that this setting is per process wide and also affects the ODBC extension, which can create some hard to debug siturations. Besides this, the PECL package, ibm_db2 seems to implement the exact same behavior which could also conflict. 
 + 
 +Proposed action: Given this feature has been marked as deprecated for so long in the manual, I think it is fair to have 2 options: 
 + 
 +  - Removal in 7.3 
 +  - Deprecation if the directive is found 
 + 
 +Implementations: 
 + 
 +  - Removal - https://gist.github.com/KalleZ/b7cc6c737801ed60c7fe793ae628b0b8 
 +  - Deprecation - https://gist.github.com/KalleZ/424ea78492cd5f4c2198cba6b25403d9
