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);
Using the function "count". <?php $foo = array("John", "Jacob", "Jingleheimer", "Schmidt"); echo count($foo); // <-- outputs the number 4 ?>
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 ?>
build an array of vowels then do a foreach on the array and then explode the string on the array value and the answer is -1 of the result
Use a for-loop starting at the length of the array and go backwards and build up a new array with the values.
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 ?>
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 ?>
Creates an array using one value for keys and other for its values http://php.net/manual/en/function.array-combine.php
plz as soon as possible give me the program for shorting an array in asscending order without using any sort function in c++
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 ?>
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 ?>
$foo = array(1.41421356, 1.61803399, 2.71828183, 3.14159265);
To merge and sort an array in PHP you need to use the array_merge() and sort() functions like shown in the example below: <?php $array1 = array(1, 5, 3, 9, 7); $array2 = array(8, 2, 6, 4, 0); // merge the arrays $merge = array_merge($array1, $array2); // 1, 5, 3, 9, 7, 8, 2, 6, 4, 0 // sort the array sort($merge); // 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ?>
