Previous Comments: ------------------------------------------------------------------------ [2007-09-18 02:27:59] tjerk dot meesters at muvee dot com Description: ------------ array_reduce() accepts an initial value to be passed as the first argument in the callback function instead of NULL. However, this initial value - if passed - is converted to an int. This is probably because the more common use of this idiom is for mathematical reduction. It would be helpful to allow other types to be passed such as strings or objects. Note: this ticket is a duplicate for #42566, but the reporter never bothered to follow up. Reproduce code: --------------- <?php echo array_reduce( array(' ','world'), create_function( '$total,$new', 'return $total.$new;' ), 'hello' ); ?> Expected result: ---------------- hello world Actual result: -------------- 0 world ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=42691&edit=1
