Utility functions to help alleviate some common use cases.
safe_read( $item, $key )Useful for accessing something without having to wrap it with empty or isset checks constantly.
Returns false if it's unable to find the item. Works with both objects and arrays.
is_constant_true( $constant )Checks the following in order:
- Constant is defined
- Constant is
true
Helpful to avoid always having to check if the constant is defined before checking the value.
Returns either true or false.
get_file( $filename, $extension )Checks that the file exists and is readable.
Allowable file types are:
- xml
- sql
- txt
- json
Returns the data of the file or false if it failed.
rrmdir( $dir )Recursively delete a directory and all files and directories inside it.
This is useful because PHP's rmdir does not delete a directory if anything exists inside of it.
Formats the given value with two decimal places, prefixed with a dollar sign.
format_currency( 1.5 )
// $1.50
