Creates an array using one value for keys and other for its values

To empty an array in PHP you need to use the unset function like shown below: <?php $array = array('hello', 'hi', 'weee'); unset($array); // empty ?>
To find the size of an array in PHP you can either use the count() function or the sizeof() function as they will produce the same result. <?php $array = array(1, 2, 3, 4, 5, 6, 7); echo count($array); // outputs 7 echo sizeof($array); // outputs 7 ?>
The array_map function in PHP loops over each elements of the passed array(s), and runs the given function. It then returns a new array that contains the values returned by each call to the given function.
To shuffle an array in PHP is easy to do, all you need to use is the shuffle() function like shown below: <?php $array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); shuffle($array); // array results will be randomly shuffled ?>
To separate a sentence into an array of words, you can use PHP's explode() function. If $text is your sentence, then use the following: $result = explode(" ", $text);
To reverse the results in a PHP array is really simple, all you need to do is use the array_reverse() function like shown below: <?php $my_array = array(1, 2, 3); $reverse_me = array_reverse($my_array); // will be stored as 3, 2, 1 now ?>
Using the function "count". <?php $foo = array("John", "Jacob", "Jingleheimer", "Schmidt"); echo count($foo); // <-- outputs the number 4 ?>
In the declaration of the receiving function, you add an ampersand. <?php function myWayCoolFunction( &$params) {.....} $x = array('1','2','3'); myWayCoolFunction($x) ?>
To pick random results from an array in PHP you will need to use the array_rand() function, you can select the amount of results you wish it too select too. <?php $array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); $rand_results = array_rand($array, 3); // will select 3 random results from the array and store in a new array ?>
Use a for-loop starting at the length of the array and go backwards and build up a new array with the values.
To check if a value is already in an array you will need to use the in_array function like shown below! <?php $values = array("pizza","hello","cheese","fred"); $newvalue = "hello"; if (in_array($newvalue, $values)) { echo "$newvalue is already in the array!"; } ?>
plz as soon as possible give me the program for shorting an array in asscending order without using any sort function in c++
