note 121951 added to function.ltrim

I noticed one thing. Suppose you have to ltrim zeroes from strings like "015", "002", etc. and convert them back to numbers, eg. using intval. Suppose you must convert to number "000" too. In this case: $trimmedString = ltrim('000', '0'); the value of $trimmedString would be NULL (and I think the docs should mention this). Anyway, I initially thought I had to conditional check for this '000', but I found that intval(NULL) returns 0 (this thing is not in the docs of intval but is in a comment) ---- Server IP: 208.43.231.9 Probable Submitter: 93.33.173.166 ---- Manual Page -- http://php.net/manual/en/function.ltrim.php Edit -- https://master.php.net/note/edit/121951 Del: integrated -- https://master.php.net/note/delete/121951/integrated Del: useless -- https://master.php.net/note/delete/121951/useless Del: bad code -- https://master.php.net/note/delete/121951/bad+code Del: spam -- https://master.php.net/note/delete/121951/spam Del: non-english -- https://master.php.net/note/delete/121951/non-english Del: in docs -- https://master.php.net/note/delete/121951/in+docs Del: other reasons-- https://master.php.net/note/delete/121951 Reject -- https://master.php.net/note/reject/121951 Search -- https://master.php.net/manage/user-notes.php
