Edit report at https://bugs.php.net/bug.php?id=55324&edit=1 ID: 55324 User updated by: kieran at menor dot dk Reported by: kieran at menor dot dk Summary: No documentation for accessing array elements with curly braces Status: Open Type: Documentation Problem Package: Documentation problem Operating System: Windows 7 PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: Made a tiny mistake. Obviously, the expected result for line 9 in the script is "a" and not "123".

Apparently, it is completely interchangeable with $var[n] for arrays as well. Is this intended? Seeing as it is only noted that strings may be accessed using curly braces, I would expect the variable to be typecast to string. Test script: --------------- <?php $foo = array('123'); $bar = 'abc'; echo $foo . "\r\n"; // Outputs "Array", as expected echo $bar . "\r\n"; // Outputs "abc", as expected echo $foo[0] . "\r\n"; // Outputs "123", as expected echo $bar[0] . "\r\n"; // Outputs "123", as expected echo $foo{0} . "\r\n"; // Outputs "123", undocumented (?), expected implicit cast to string, thus expected the output to be "A" echo $bar{0} . "\r\n"; // Outputs "a", as expected ?> Expected result: ---------------- Array abc 123 a A a Actual result: -------------- Array abc 123 a 123 a ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55324&edit=1
