note 59565 added to language.types.string

For heredocs, the manual is accurate. Many other descriptions on the web are not. PHP always tries to evaluate variables. So if you want a $ sign, it always needs to be escaped or in complex format, depending on the context. This is especially important if you are trying to do an eval(). <?php $foo = 1; $code = <<<CODE $bar = $foo; CODE; eval ($code); // doesn't work ?> <?php $foo = 1; $code = <<<CODE \$bar = \$foo; CODE; eval ($code); // $bar = $foo; ?> <?php $foo = 1; $code = <<<CODE \$bar = {$foo}; CODE; eval ($code); // $bar = 1; ?> <?php $foo = 1; $code = <<<CODE {$bar} = {$foo}; CODE; eval ($code); // doesn't work ?> ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59565 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59565&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59565&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59565&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59565&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59565&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59565&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59565&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59565&report=yes Search -- http://master.php.net/manage/user-notes.php
