note 78067 added to language.types.string

If you want to use a variable in an array index within a double quoted string you have to realize that when you put the curly braces around the array, everything inside the curly braces gets evaluated as if it were outside a string. Here are some examples: <?php $i = 0; $myArray[Person0] = Bob; $myArray[Person1] = George; // prints Bob (the ++ is used to emphasize that the expression inside the {} is really being evaluated.) echo "{$myArray['Person'.$i++]}<br>"; // these print George echo "{$myArray['Person'.$i]}<br>"; echo "{$myArray["Person{$i}"]}<br>"; // These don't work echo "{$myArray['Person$i']}<br>"; echo "{$myArray['Person'$i]}<br>"; // These both throw fatal errors // echo "$myArray[Person$i]<br>"; //echo "$myArray[Person{$i}]<br>"; ?> ---- Server IP: 208.69.120.35 Probable Submitter: 155.98.27.144 ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- https://master.php.net/note/edit/78067 Del: integrated -- https://master.php.net/note/delete/78067/integrated Del: useless -- https://master.php.net/note/delete/78067/useless Del: bad code -- https://master.php.net/note/delete/78067/bad+code Del: spam -- https://master.php.net/note/delete/78067/spam Del: non-english -- https://master.php.net/note/delete/78067/non-english Del: in docs -- https://master.php.net/note/delete/78067/in+docs Del: other reasons-- https://master.php.net/note/delete/78067 Reject -- https://master.php.net/note/reject/78067 Search -- https://master.php.net/manage/user-notes.php
