You don’t. Your array doesn’t have a key [1]. You could: Make a new array, which contains the keys: $newArray = array_keys($array); echo $newArray[0]; But the value “one” is at $newArray[0], not [1]. A shortcut would be: echo current(array_keys($array)); Get the first key of the array: reset($array); echo key($array); Get the key corresponding to the … Read more
Your $userData must have exactly the same placeholders bound by your statement, no more and no fewer. See PDOStatement::execute documentation, the part that says “You cannot bind more values than specified”. You need to prepare your argument to execute() to match your binds exactly. This is easy with array_intersect_key() if you arrange your arrays correctly. … Read more
Glib’s hash table. implements a map interface or (associative array). And it’s most likely the most used hash table implementation for C. GHashTable *table=g_hash_table_new(g_str_hash, g_str_equal); /* put */ g_hash_table_insert(table,”SOME_KEY”,”SOME_VALUE”); /* get */ gchar *value = (gchar *) g_hash_table_lookup(table,”SOME_KEY”);
Keep 2 data structures: A dictionary of words -> count. Just use an ordinary HashMap<String, Long>. An “array” to keep track of order, such that list[count] holds a Set<String> of words with that count. I’m writing this as though it were an array as a notational convenience. In fact, you probably don’t know an upper … Read more
JavaScript has no associative arrays, just objects. Even JavaScript arrays are basically just objects, just with the special thing that the property names are numbers (0,1,…). So look at your code first: var myArray = []; // Creating a new array object myArray[‘a’] = 200; // Setting the attribute a to 200 myArray[‘b’] = 300; … Read more
Just use: $output = array_merge($array1, $array2); That should solve it. Because you use string keys if one key occurs more than one time (like ’44’ in your example) one key will overwrite preceding ones with the same name. Because in your case they both have the same value anyway it doesn’t matter and it will … Read more
Just use array_merge or array_replace. array_merge works by starting with the array you give it (in the proper order) and overwriting/adding the keys with data from your actual array: $customer[‘address’] = ‘123 fake st’; $customer[‘name’] = ‘Tim’; $customer[‘dob’] = ’12/08/1986′; $customer[‘dontSortMe’] = ‘this value doesnt need to be sorted’; $properOrderedArray = array_merge(array_flip(array(‘name’, ‘dob’, ‘address’)), $customer); … Read more
Can’t you just do: $resulting_array = $array2 + $array1; ?
$arr = array(); foreach ($old_arr as $key => $item) { $arr[$item[‘id’]][$key] = $item; } ksort($arr, SORT_NUMERIC);
Why not just use $dataarray[$row[‘id’]] = $row[‘data’]; ?
