array
listLanguages()
Returns a list of languages in use by the system.
In the interests of brevity and sanity a full list is not provided. Add entries that you want to use to the array using ISO 639-1 two-letter language codes, which you can find at: https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes. Be aware that deleting entries that are in use by your content objects will cause errors.

string
encodeEscapeUrl(string $url)
URL-encode and escape a query string for use in a URL.
Trims, checks for UTF-8 compliance, rawurlencodes and then escapes with htmlspecialchars(). If you wish to use the data on a landing page you must decode it with htmlspecialchars_decode() followed by rawurldecode() in that order. But really, if you are using any characters that need to be encoded in the first place you should probably just stop.

bool
isAlnum(string $alnum)
Check that a string is comprised solely of alphanumeric characters.
Accented regional characters are rejected. This method is designed to be used to check database identifiers or object property names.
in ValidateString at line 77
bool
isAlnumUnderscore(string $alnumUnderscore)
Check that a string is comprised solely of alphanumeric characters and underscores.
Accented regional characters are rejected. This method is designed to be used to check database identifiers or object property names.
in ValidateString at line 95
bool
isAlpha(string $alpha)
Check that a string is comprised solely of alphabetical characters.
Tolerates vanilla ASCII only. Accented regional characters are rejected. This method is designed to be used to check database identifiers or object property names.
in ValidateString at line 113
bool
isUtf8(string $text)
Check if the character encoding of text is UTF-8.
All strings received from external sources must be passed through this function, particularly prior to storage in the database.
in ValidateString at line 131
string
trimString(mixed $text)
Cast to string, check UTF-8 encoding and strip trailing whitespace and control characters.
Removes trailing whitespace and control characters (ASCII <= 32 / UTF-8 points 0-32 inclusive), checks for UTF-8 character set and casts input to a string. Note that the data returned by this function still requires escaping at the point of use; it is not database or XSS safe.
As the input is cast to a string do NOT apply this function to non-string types (int, float, bool, object, resource, null, array, etc).
