Back in April, I posted about creating JWS.app and I knew at the time that there were issues with it. This new “Fixing JWS.app” series is all about addressing those issues. The first thing that we are fixing is the nav bar. Let’s look at what we are dealing with.

Back in 2011, I wrote few short posts about what I install right after reinstalling windows. I figured that 9 years is enough time between these kinds of posts. This time, I’m going to go over my prefered tools for writing code.
Continue reading "My prefered tools for coding"For day 21 of 21 in the “PHP Function of the day” series, I’m going to look at sha1(). This is similar to the md5() function that we looked at on day 12. I’ll start by saying that sha1 isn’t great and should not be used for storing password hashes. Let’s take a look. <?php $stringToHash = …
Continue reading "PHP function of the day: sha1()"For day 20 of 21 in the “PHP Function of the day” series, I’m going to look at array_rand(). The function takes a required array and an optional number of random keys to return. It returns a random key (not the value). Let’s take a look. <?php $names = array(“Joe”,”Jim”,”Sarah”,”Jill”); $numbers = array(1,2,3,4,5,6,7,8,9); $names_rand_keys = array_rand($names,3); $numbers_rand_keys …

Let’s take a look. <?php $shoppingDay=date_create(“2020-05-28”); $payDay=date_create(“2020-06-01”); $difference = date_diff($shoppingDay,$payDay); print_r($difference); echo “<br /><br />”.$difference->format(“%R%a days”); ?> See the output As you an see, this calculates the difference between two dates (something that could be pretty …
Continue reading "PHP function of the day: date_diff()"For day 18 of 21 in the “PHP Function of the day” series, I’m going to look at srand(). The function lets you specify the seed for rand(). In modern versions of PHP, rand() is seeded automatically and there is no real reason to do this. So, why the explanation? YOLO? 🙂 Let’s take a look. <?php …
Continue reading "PHP function of the day: srand()"For day 17 of 21 in the “PHP Function of the day” series, I’m going to look at print_r(). We have already used print_r() on days 4, 5, and 11. Let’s take a look. <?php $num = 123; $str = “Joe”; $arr = array(1, 2, 3); print_r($num); print_r($str); print_r($arr); ?> See the output As you …
Continue reading "PHP function of the day: print_r()"For day 16 of 21 in the “PHP Function of the day” series, I’m going to look at printf(). This one is pretty interesting. It allows you to define a format and a series of arguments. The “%[something]” in the format string is used to define both where the argument’s value is output and the expected format. …
Continue reading "PHP function of the day: printf()"For day 15 of 21 in the “PHP Function of the day” series, I’m going to look at array_flip(). As you might guess, this function “flips” the array so that the key is the value and the value is the key. Let’s take a look. <?php $joe = array(“fname”=>”Joe”,”lname”=>”Steinbring”,”website”=>”jws.dev”); print_r($joe); echo(“<br />”); print_r(array_flip($joe)); echo(“<br /><br />”); $foods …
Continue reading "PHP function of the day: array_flip()"For day 14 of 21 in the “PHP Function of the day” series, I’m going to look at date(). The function takes a required format and an optional timestamp and outputs a formatted date. Let’s take a look. <?php echo “This is the “.date(“d”).”th day of the month.”.”<br />”; echo “This is the “.date(“m”).”th month of the …
