Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php SORT_ASC, SORT_DESC, etc. are constants, not strings, so just treat them as if they were numeric values: $sortFlag = SORT_ASC; $new_array = array_column_sort($someArray,'column',$sortFlag) Previous Comments: ------------------------------------------------------------------------ [2003-10-15 08:25:18] it at oh-barcelona dot com Description: ------------ Hello, I've found a perplexing bug with sorting flags. When you create a function to create (for example) an dynamic array_multisort() and one of the arguements which is passed is a SORT_ASC (or any other flag) which is used to create the array_multisort() it MUST be passed without quotes and not as a string. In the example below you will see that if you gettype() of the $arg the SORT_DESC returns an integer not a string when passed without quotes and a string with. If the SORT flag is passed as a string the array_multisort acts as if it were null. This stops me from setting the SORT flag via if statement. I have written a work around but this problem should be addressed because if you settype() a string it becomes "0". The function call is: $ new_array = array_column_sort($someArray,'column',SORT_DESC) The function does not work if you use: $sortFlag = "SORT_ASC"; $ new_array = array_column_sort($someArray,'column',$sortFlag ) Reproduce code: --------------- function array_column_sort(){ $args = func_get_args(); $array = array_shift($args); // make a temporary copy of array for which will fix the // keys to be strings, so that array_multisort() doesn't // destroy them $array_mod = array(); foreach ($array as $key => $value) $array_mod['_' . $key] = $value; $i = 0; $multi_sort_line = "return array_multisort( "; foreach ($args as $arg) { $i++; if ( is_string($arg) ){ foreach ($array_mod as $row_key => $row){ $sort_array[$i][] = $row[$arg]; } }else{ $sort_array[$i] = $arg; } $multi_sort_line .= "\$sort_array[" . $i . "], "; } $multi_sort_line .= "\$array_mod );"; eval($multi_sort_line); // now copy $array_mod back into $array, stripping off the "_" // that we added earlier. $array = array(); foreach ($array_mod as $key => $value) $array[ substr($key, 1) ] = $value; return $array; } Expected result: ---------------- The array should be sorted by column and SORT flag. Actual result: -------------- The array_multisort only excepts the SORT flag without quotes and not as a string. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25879&edit=1
