Why objects (usually) use less memory than arrays in PHP

This is just a small post in response to [this tweet][tweet] by Julien Pauli (who by the way is the release manager for PHP 5.5). In the tweet he claims that objects use more memory than arrays in PHP. Even though it can be like that, it's not true in most cases. (Note: This only applies to PHP 5.4 or newer.)

The reason why it's easy to assume that objects are larger than arrays is because objects can be seen as an array of properties and a bit of additional information (like the class it belongs to). And as array + additional info > array it obviously follows that objects are larger. The thing is that in most cases PHP can optimize the array part of it away. So how does that work?

The key here is that objects usually have a predefined set of keys, whereas arrays don't:

# Uncomment if you want the script to always use the scripts
# directory as the folder to look through
#REPOSITORIES="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
REPOSITORIES=`pwd`

IFS=$'\n'

# Rename tags named foo-bar-#.#.# to v#.#.# and push the tag changes
git tag -l | while read t; do n="v${t##*-}"; git tag $n $t; git push --tags ; git tag -d $t; git push origin :refs/tags/$t ; done

Toolbox PhpStorm.app Mac integration with Tower.app for diff and merge

How to use this

1. Add CompareTools.plist and phpstorm-toolbox.sh files in the ~/Library/Application Support/com.fournova.Tower3/CompareTools/ directory. You may need to mkdir ~/Library/Application\ Support/com.fournova.Tower3/CompareTools if the folder does not already exist
2. Update the phpstorm-toolbox.sh to use your username for the /Users/yourusername/ path and the correct version number (PhpStorm > About > Build #PS-XXX.XXXXX.XX where XXX.XXXXX.XX is the version number to use).
3. Run chmod +x ~/Library/Application\ Support/com.fournova.Tower3/CompareTools/phpstorm-toolbox.sh
4. Go into Tower.app Preference > Git Config > Select "PhpStorm" for "Diff tool" and "Compare tool", you can optionally enable "Perform directory diff"
