note 129085 added to function.printf

When using the <?= ?> syntax to print out the result, be aware that printf() returns the length of string after echoing out the result, so the following will happen: Source code: ``` <p>Total: <?= printf('%.2f', 1+2) ?></p> ``` will result in: Total: 3.004 when it should be: Total: 3.00 Use sprintf() for using <?= ?> syntax, which returns the formatted string itself. ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.157.134 (proxied: 2001:e68:541a:68ab:70d1:a4f8:2b90:194e) ---- Manual Page -- https://php.net/manual/en/function.printf.php Edit -- https://main.php.net/note/edit/129085 Del: integrated -- https://main.php.net/note/delete/129085/integrated Del: useless -- https://main.php.net/note/delete/129085/useless Del: bad code -- https://main.php.net/note/delete/129085/bad+code Del: spam -- https://main.php.net/note/delete/129085/spam Del: non-english -- https://main.php.net/note/delete/129085/non-english Del: in docs -- https://main.php.net/note/delete/129085/in+docs Del: other reasons-- https://main.php.net/note/delete/129085 Reject -- https://main.php.net/note/reject/129085 Search -- https://main.php.net/manage/user-notes.php
