| ===== Proposal ===== | ===== Proposal ===== |
| The ''fgetss()'' function and the ''string.strip_tags'' stream filters expose the functionality of ''strip_tags()'' in a streaming matter. The need to support these makes the implementation of ''strip_tags()'' more complicated, as a streaming state machine is necessary. On the other hand, these functions seem to be of very little utility. ''strip_tags()'' itself, due to its limitations and known bugs, already has very few legitimate applications. There is no need to provide native support for streaming application on top of that. | The ''fgetss()'' function and the ''string.strip_tags'' stream filters expose the functionality of ''strip_tags()'' in a streaming matter.

| Proposed action: Mark ''fgetss()'' and ''SplFileObject::fgetss()'' as deprecated, so that a deprecation notice is emitted on every call. Generate a deprecation notice if the ''string.strip_tags'' stream filter is created. In PHP 8 the functions and the stream filter are removed. | Proposed action: Mark ''fgetss()'', ''gzgetss()'' and ''SplFileObject::fgetss()'' as deprecated, so that a deprecation notice is emitted on every call.

| 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, promising removal in a future version of PHP. This ini directive modifies the DB2INSTANCE environment variable for non Windows 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 process wide and also affects the ODBC extension, which can create some hard to debug situations. Besides this, the PECL package, ibm_db2 seems to implement the exact same behavior which could also conflict. |
| | |
| | Proposed action: Add a deprecation notice if the ini directive has a value at module initialization. |
