note 99289 added to function.strtolower

The code in example 1 did not work for me while the variable "$str" was self referencing. A simple fix is to add a 2nd variable to store the data from the "lower case" functions output. <?php $str = "Mary Had A Little Lamb and She LOVED It So"; $str_lwr = strtolower($str); echo $str_lwr; // Prints mary had a little lamb and she loved it so ?> ---- Server IP: 69.147.83.197 Probable Submitter: 69.243.202.204 ---- Manual Page -- http://www.php.net/manual/en/function.strtolower.php Edit -- https://master.php.net/note/edit/99289 Del: integrated -- https://master.php.net/note/delete/99289/integrated Del: useless -- https://master.php.net/note/delete/99289/useless Del: bad code -- https://master.php.net/note/delete/99289/bad+code Del: spam -- https://master.php.net/note/delete/99289/spam Del: non-english -- https://master.php.net/note/delete/99289/non-english Del: in docs -- https://master.php.net/note/delete/99289/in+docs Del: other reasons-- https://master.php.net/note/delete/99289 Reject -- https://master.php.net/note/reject/99289 Search -- https://master.php.net/manage/user-notes.php
