Christian Weiske:
PHP: Allowed memory size exhausted
Jul 12, 2016 @ 17:17:20

Christian Weiske has a post to his site with a reminder about a common misconception that can happen because of the wording in a standard PHP message about memory exhaustion.

The indieweb.org wiki has a page about Wordpress with a Criticism section. ?

One of those "issues" listed is Fatal Error memory exhausted [...but] I removed that section because it's nonsense to list a server configuration issue as Criticism.

While the admins reverted the change to put the message back, Christian clarified what meaning of the error message to help clarify the situation. In the case if the example message, the "32 bytes" it mentions is not the amount of total memory it's trying to allocate, it's the amount it last tried and failed at. Christian also points out the role that PHP's own memory_limit setting has on when this message might pop up.

PHP to get enum/set values from mysql field
Jan 21, 2010 @ 17:14:26

Giulio Pons has a quick post with a code snippet showing how to grab the possible values for an ENUM or SET field on a MySQL database.

This function returns an array with the elements allowed in a ENUM or SET mysql field. This can be usefull if you’re making some automation and need to retrieve those values without writing them in your code.

The function uses the database's metadata to get the column information for a table and filter out the "enum" information from that. The column information includes the set of values possible and a few simple string handling functions make it easy to grab them. They could also be replaced by a regular expression or two to grab the same information more concisely.
