This filter modifies a given string such that certain characters are removed from the beginning and end.
The following options are supported for Zend_Filter_StringTrim:
A basic example of usage is below:
1 2 3 | $filter = new Zend_Filter_StringTrim();
print $filter->filter(' This is (my) content: ');
|
The above example returns ‘This is (my) content:’. Notice that the whitespace characters have been removed.
1 2 3 4 | $filter = new Zend_Filter_StringTrim(':');
// or new Zend_Filter_StringTrim(array('charlist' => ':'));
print $filter->filter(' This is (my) content:');
|
The above example returns ‘This is (my) content’. Notice that the whitespace characters and colon are removed. You can also provide an instance of Zend_Config or an array with a ‘charlist’ key. To set the desired character list after instantiation, use the setCharList() method. The getCharList() return the values set for charlist.
