For day 10 of 21 in the “PHP Function of the day” series, I’m going to look at time(). It simply gets the number of seconds elapsed since the Unix Epoch. Let’s take a look. <?php echo ‘It has been ‘.time().’ seconds since January 1 1970 00:00:00 GMT’; ?> See the output This has pretty …

This function takes values and returns the smallest value from what you provided. Let’s take a look. <?php echo(min(-1,0,1,2,3).'<br />’); echo(min(array(-1,0,1,2,3)).'<br />’); echo(min(array(‘a’,’b’,’c’,’d’))); ?> See the output As you can see, this is a lot like …

Let’s take a look. <?php $html = ‘<h1>Hello!</h1><p>Joe\’s website is at: <a href=”https://jws.dev”>jws.dev</a></p>’; $encoded = htmlentities($html); echo $encoded.'<br />’; echo html_entity_decode($encoded); ?> See the output As you …

It takes HTML as an input and converts it to HTML entities. Let’s take a look. <?php $html = ‘<h1>Hello!</h1><p>Joe\’s website is at: <a href=”https://jws.dev”>jws.dev</a></p>’; echo ‘<br />’; echo $html; echo ‘<br />’; echo htmlentities($html); ?> See …

Where json_encode() encodes data as JSON, json_decode() decodes JSON data. Let’s take a look. <?php $data = ‘{“First_Name”:”Joe”,”Last_Name”:”Steinbring”,”Website”:”jws.dev”}’; var_dump($data); echo(‘<br />’); var_dump(json_decode($data)); echo(‘<br />’); var_dump(json_decode($data, true)); ?> See the output …

Let’s take a look. <?php $array = array(1, 2, 3, 4); print_r($array); echo(“<br />”); $array = array(“Joe”, “Paul”, “Lisa”); print_r($array); echo(“<br />”); $array = array(“Name”=>”Joe”,”Address”=>”123 N Main …
Continue reading "PHP function of the day: array()"For day 4 of 21 in the “PHP Function of the day” series, I’m going to look at gettimeofday(). The function gets the current time of the day. Let’s take a look. <?php print_r(gettimeofday()); ?> See the output Since gettimeofday() outputs an array, we are using print_r() instead of echo() but don’t focus …

This function takes values and returns the highest value from what you provided. Let’s take a look. <?php echo(max(-1,0,1,2,3).'<br />’); echo(max(array(-1,0,1,2,3)).'<br />’); echo(max(array(‘a’,’b’,’c’,’d’))); ?> See the output You can provide a comma-delimited list or …
Continue reading "PHP function of the day: max()"For day 2 of 21 in the “PHP Function of the day” series, I’m going to look at echo(). It is basic enough that I kind of already used it in yesterday’s post. Echo just prints a value to the page. <?php $numberVar = 123; $textVar = ‘Joe is here!’; $arrayVar = array(1, 2, 3); …
Continue reading "PHP function of the day: echo()"This is the first of 21 posts in my “PHP Function of the day” series. These are going to be quicker posts, for the most part. Maybe I should do it with other languages after this? 🙂 For today, let’s look at json_encode(). <?php $joe = array(“First_Name”=>”Joe”, “Last_Name”=>”Steinbring”, “Website”=>”jws.dev”); echo ‘The Array: <br />’; echo …
