substr		Extracts parts of a string from a specified character's position and returns the specified number of characters.		2017-02-01	2017-02-01	2017-02-01	functions	strings						false

substr extracts parts of a string, beginning at the character at the specified position, and returns the specified number of characters.

It normally takes two parameters: start and length. It can also take one parameter: start, i.e. length is omitted, in which case the substring starting from start until the end of the string will be returned.

To extract characters from the end of the string, use a negative start number.

In addition, borrowing from the extended behavior described at http://php.net substr, if length is given and is negative, that number of characters will be omitted from the end of string.

{{substr "BatMan" 0 -3}} → "Bat"
{{substr "BatMan" 3 3}} → "Man"
