To convert an object to associative array in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−Before conversion: object(department)#1 (2) { ["deptname"]=> string(9) "Marketing" ["deptzone"]=> string(5) "South" } After conversion: array(2) { ["deptname"]=> string(9) "Marketing" ["deptzone"]=> string(5) "South" }ExampleLet us now see another example − Live DemoOutputThis will produce the following output−Before conversion: object(department)#1 (2) { ["deptname"]=> string(9) "Marketing" ["deptzone"]=> string(5) "South" } After conversion: array(2) { ["deptname"]=> string(9) "Marketing" ["deptzone"]=> string(5) "South" }
To change date format in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−Displaying date... Date = 2019-11-11 05:25 PM Displaying updated date... 2019-12-01 17:25ExampleLet us now see another example− Live DemoOutputThis will produce the following output−Displaying date... 2019/11/11 00:00:00
To add an item at the beginning of the associative array, the code is as follows−Example Live DemoOutputThis will produce the following output−Initial Array... Array( [p] => 150 [q] => 100 [r] => 120 [s] => 110 [t] => 115 [u] => 103 [v] => 105 [w] => 125 ) Updated Array... Array ( [0] => 100 [p] => 150 [q] => 100 [r] => 120 [s] => 110 [t] => 115 [u] => 103 [v] => 105 [w] => 125 )ExampleLet us now see another example− Live DemoOutputThis will produce the following output−Initial Array... Array( [0] => Ryan [1] => Kevin [2] => Jack ) Updated Array... Array( [0] => Katie [1] => Ryan [2] => Kevin [3] => Jack )
In the Double not operator (!!), the first not i.e. ! is used to negate a value, whereas the second not i.e.! again negates. To implement Double not operator in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−Value = 0.1 Double Negated Value = 1ExampleLet us now see another example − Live DemoOutputThis will produce the following output−String = 100.56 Number (Converted from String) = 100.56 Double Negated Value = 1
To convert a string into a number, the code is as follows−Example Live DemoOutputThis will produce the following output−Number (Converted from String) = 150ExampleLet us now see another example− Live DemoOutputThis will produce the following output−String = 100.56 Number (Converted from String) = 100.56
To convert number to month name in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−Displaying date... Date = 2019-11-11 Month = November Displaying updated date... 2019-12-01ExampleLet us now see another example − Live DemoOutputThis will produce the following output −Displaying date... Date = 2019-11-11 Month = November Displaying updated date... 2019-12-01 Month = December
To create a comma-separated list from an array in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−Array with leading and trailing whitespaces... Value = John Value = Jacob Value = Tom Value = Tim Comma separated list... John , Jacob , Tom , Tim Updated Array... Value = John Value = Jacob Value = Tom Value = TimExampleLet us now see another example − Live DemoOutputThis will produce the following output−Comma separated list... 100, 200, 300, 400, 500
To get a variable name as a string in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−This is it!ExampleLet us now see another example − Live DemoOutputThis will produce the following output−Val
