PHP large file upload fails error code 7 (Apache)

admin — Tue, 08 Nov 2011 09:29:06 +0000

Don’t forget kids to check the size of the tmp partition if you are having issues uploading large files with PHP.

After setting all the usual configuration directives (upload_max_filesize, post_max_size etc) uploads were still failing for me returning error code 7.

After poking around on the Debian VPS for a while I realised the /tmp partition was 128mb!!

Luckily you can set the path for file uploads using the following directive:

1	upload_tmp_dir = /path/to/somewhere/with/some/disk/space

Using CakePHP log() in a vendor class

The proper way to do this is with a static call to Debugger:

1	Debugger::log($output);

$things = array('a','b','c','d');

unset($things[0]);

print_r($things); 

#outputs

#Array

#(

#    [1] => b

#    [2] => c

#    [3] => d

#)

# Actually do the reset.

$things = array_values($things);

print_r($things);

#outputs 

#Array

#(

#    [0] => b

#    [1] => c

#    [2] => d

Mount remote file system on your local file system over SSH – SSHFS

Lots of love going about today! This time, the recipient is SSHFS which allows you to mount a remote filing system onto your local tree over SSH. In a virtual hosting environment (/vhosts/ etc) it’s pure joy to work with.

You’ll need to install SSHFS on the client (the machine you want to mount the remote system on). All you need on the remote system is SSH. This is already installed on most systems.

You can install SSHFS on OSX with Mac Ports:

1	port install sshfs

On the local client system add the user you’re going to connect with to the fuse group. That group was created when you installed SSHFS:

1	gpasswd -a localuser fuse

Create a directory on the local filing system to use as a mount point:

1	mkdir /vhosts_servername/

Now connect to the remote system using a command line like this on the client:

1	sshfs localuser@yourdomain.com:/remote_directory/ /vhosts_servername

MySQL GROUP_CONCAT concatenated grouping

admin — Sun, 18 Jan 2009 10:40:29 +0000

Group and concatenate MySQL results and in this case make them distinct (unique):

1	GROUP_CONCAT(DISTINCT landing_id ORDER BY landing_id SEPARATOR ',') as landing_ids

This produces a series of values separated by comas: 1,2,3,4,5.

Useful component of sub/nested queries.

MySQL export SQL query as file

This will dump an SQL statement into a file:

1	mysql -u username -p database_name -e "SQL_STATEMENT" > file.data
