note 119689 added to function.echo

The {} syntax is useful for printing non array variables as well, an example to illustrate: <?php $foo = "foobar"; $bar = "barbaz"; //Will produce the error: Undefined variable: $foo_ echo "$foo_$bar"; //Will print the intended string: "foobar_barbaz" echo "{$foo}_$bar"; ?> Could even be worth getting into the habit of enclosing all variables in {} when writing echo strings, to be on the safe side. ---- Server IP: 72.52.91.14 Probable Submitter: 81.2.65.214 ---- Manual Page -- http://php.net/manual/en/function.echo.php Edit -- https://master.php.net/note/edit/119689 Del: integrated -- https://master.php.net/note/delete/119689/integrated Del: useless -- https://master.php.net/note/delete/119689/useless Del: bad code -- https://master.php.net/note/delete/119689/bad+code Del: spam -- https://master.php.net/note/delete/119689/spam Del: non-english -- https://master.php.net/note/delete/119689/non-english Del: in docs -- https://master.php.net/note/delete/119689/in+docs Del: other reasons-- https://master.php.net/note/delete/119689 Reject -- https://master.php.net/note/reject/119689 Search -- https://master.php.net/manage/user-notes.php
