note 109449 added to function.array-combine

I was looking for a function that could combine an array to multiple one, for my MySQL GROUP_CONCAT() query, so I made this function. <?php function array_combine_array(array $keys) { $arrays = func_get_args(); $keys = array_shift($arrays); /* Checking if arrays are on the same model (array('INDEX'=> array()) or array()) */ $check = count(array_unique(array_map('is_array',array_map('current',$arrays)))) === 1; if (!$check) { trigger_error('Function array_combine_array() expects all parameters to be same type array or array of array',E_USER_NOTICE); return array(); } /* Checking the model of arrays, array('INDEX' => array()) or Array() */ $assocArray = is_array(array_shift(array_map('current',$arrays))); /* If empty $Keys is given, we fill an empty array */ if (empty($keys)) $keys = array_keys(array_fill(0,max(($assocArray) ? array_map('count',array_map('current',$arrays)) : array_map('count',$arrays)),'foo')); /* Init */ $ret=array();$i=0; /* Cycling on each keys values, making an offset for each */ foreach($keys as $v) { /* Cycling on arrays */ foreach ($arrays as $k) { if ($assocArray) { /* Getting the index of the element */ $key = key($k); /* If the offset exists, we place it */ $ret[$v][$key] = isset($k[$key][$i]) ? $k[$key][$i]:false; } /* Making the array with auto-made index */ else $ret[$v][] = isset($k[$i]) ? $k[$i]: false; } /* Getting the next offset */ $i++; } return $ret; } /* Examples */ $r = array(1,2,4,10); $a1 = array('one','two','four','ten'); $a2 = array('un','deux','quatre','dix'); $a3 = array('uno','dos','quatro','diez'); print_r(array_combine_array($r,array('english' => $a1),array('french' => $a2),array('spanish' => $a3))); /* Associative index, associative subarray indexes */ print_r(array_combine_array($r,$a1,array('french' => $a2),array('spanish' => $a3))); /* Ouputs Error */ print_r(array_combine_array($r,$a1,$a2,$a3)); /* Associative index, auto-made subarray indexes */ print_r(array_combine_array(array(),array('english' => $a1),array('french' => $a2),array('spanish' => $a3))); /* Auto-made index, associative subarray indexes */ ?> ---- Server IP: 195.221.21.36 Probable Submitter: 80.14.183.9 ---- Manual Page -- http://www.php.net/manual/en/function.array-combine.php Edit -- https://master.php.net/note/edit/109449 Del: integrated -- https://master.php.net/note/delete/109449/integrated Del: useless -- https://master.php.net/note/delete/109449/useless Del: bad code -- https://master.php.net/note/delete/109449/bad+code Del: spam -- https://master.php.net/note/delete/109449/spam Del: non-english -- https://master.php.net/note/delete/109449/non-english Del: in docs -- https://master.php.net/note/delete/109449/in+docs Del: other reasons-- https://master.php.net/note/delete/109449 Reject -- https://master.php.net/note/reject/109449 Search -- https://master.php.net/manage/user-notes.php
