Leopard (10.5) was the first release of MacOS that included PHP 5 support. However by default it is disabled.
To enable it you need to uncomment (remove the #) from the following line in /private/etc/apache2/httpd.conf.

#LoadModule php5_module libexec/apache2/

Then restart apache

sudo /usr/sbin/apachectl restart

When processing a large file (for example using ‘LOAD DATA LOCAL INFILE’) the connection to mysql can get lost. Reason for this is the mysql server has a limit on the size of a ‘packet’ it receives and when this limit is exceeded it drops the connection.

This limit can be changed using the system variable max_allowed_packet. This specifies the maximum size of a packet in bytes.

A packet is a single SQL statement sent to the MySQL server, a single row that is sent to the client, or a binary log event sent from a master replication server to a slave.
