Answer 1

Yes we can, copy & paste the following code on an empty PHP code.

<?php
/*
Example:
Use variables for array keys, the variable's value is used as the key.

Notice that we use print_r to dump raw array into the output.
*/
$nama = "name";
$almt = "address";

$arr = array($nama=>"Your name", $almt=>"Your address");

echo "<p>We have the following code:
<pre><code>
\$nama = \"name\";
\$almt = \"address\";

\$arr = array(\$nama=>\"Your name\", \$almt=>\"Your address\");
</code></pre>
</p>";

echo "<p>And so here's the array contents</p><strong>";
print_r($arr);
echo "</strong>";
unset($arr);

/*
Example:
Create and access array element by key using different type of quotes.

Note that during array creation we use single quotes to assign the array keys. But when we use/access them we use double quotes.
*/
echo "<hr /><p>And we have this code:
<pre><code>
\$arr = array('name'=>'SoloLearner', 'address'=>'planet Earth');
echo \"&lt;p&gt;Hello, I am a \" . \$arr[\"name\"] . \" from \" . \$arr[\"address\"] . \"&lt;/p&gt;\";
</code></pre></p>
<p>With the following output:<br />";

$arr = array('name'=>'SoloLearner', 'address'=>'planet Earth');

echo "<p><strong>Hello, I am a " . $arr["name"] . " from " . $arr["address"] . "</strong></p>";
?>
