note 73400 added to language.types.string

It may be obvious to some, but it's convenient to note that variables _will_ be expanded inside of single quotes if these occur inside of a double-quoted string. This can be handy in constructing exec calls with complex data to be passed to other programs. e.g.: $foo = "green"; echo "the grass is $foo"; the grass is green echo 'the grass is $foo'; the grass is $foo echo "the grass is '$foo'"; the grass is 'green' ---- Server IP: 64.71.164.2 Probable Submitter: 70.112.241.55 ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- https://master.php.net/note/edit/73400 Del: integrated -- https://master.php.net/note/delete/73400/integrated Del: useless -- https://master.php.net/note/delete/73400/useless Del: bad code -- https://master.php.net/note/delete/73400/bad+code Del: spam -- https://master.php.net/note/delete/73400/spam Del: non-english -- https://master.php.net/note/delete/73400/non-english Del: in docs -- https://master.php.net/note/delete/73400/in+docs Del: other reasons-- https://master.php.net/note/delete/73400 Reject -- https://master.php.net/note/reject/73400 Search -- https://master.php.net/manage/user-notes.php
