[mapserver-users] PHP-Mapscript and PHP Apache DSO - any progress?

[William Kyngesburye]

Google to the rescue.  So it's a build option for Apache 2.2.  It looks like Apache in OS X (10.6+) uses prefork.  So I guess we're good to go on this.

"Mon Dieu! but they are all alike.  Cheating, murdering, lying, fighting, and all for things that the beasts of the jungle would not deign to possess - money to purchase the effeminate pleasures of weaklings.  And yet withal bound down by silly customs that make them slaves to their unhappy lot while firm in the belief that they be the lords of creation enjoying the only real pleasures of existence....
