<p>This function will strip tags from a string, split it at a defined
|
|||
|
|
maximum length, and insert an ellipsis.</p>
|
|||
|
|
<p>The first parameter is the string to ellipsize, the second is the number
|
|||
|
|
of characters in the final string. The third parameter is where in the
|
|||
|
|
string the ellipsis should appear from 0 - 1, left to right. For
|
|||
|
|
example. a value of 1 will place the ellipsis at the right of the
|
|||
|
|
string, .5 in the middle, and 0 at the left.</p>
|
|||
|
|
<p>An optional forth parameter is the kind of ellipsis. By default,
