Routine Second Time#

It seems that there are indeed many things, but I don't know what they mean in daily life;

PHP Variable Variables (Dynamic Variables)#

// Zero - index.php
echo "<h3>Zero</h3>";
$animal = 'turtles';
$turtles = 103;
print $$animal;
// The output here is the same as:
// print $turtles

Using this syntax, the view layer (View) can be separated to achieve the "template mechanism";

Reference:
"PHP: Variable Variables - php.net"
"MVC Framework_Baidu Baike"
;

Main Text#

Note: The part in the comment - index.php indicates which file the code should be placed in;

// Data for display - index.php
$tags = array(
  "blog" => "https://www.wdssmq.com",
  "name" => "Sinking Ice and Floating Water",
  "afdian" => "https://afdian.net/@wdssmq"
);

Output each item of the above array as a paragraph;

// One - index.php
echo "<h3>One</h3>";
foreach ($tags as $key => $value) {
  echo "<p>{$key}: {$value}</p>";
}

// Two - index.php
echo "<h3>Two</h3>";
foreach ($tags as $key => $value) {
  $$key = $value;
}
echo "<p>name: {$name}</p>";
echo "<p>blog: {$blog}</p>";
echo "<p>afdian: {$afdian}</p>";

Method "One" is a basic loop usage, and the output order is consistent with the element order when assigning variables;

Method "Two" uses the "variable variable" syntax to create a separate variable for each element in the array, with the variable name being the key name (field name) of each array element;

Then adjust the order when outputting, so you don't need to care about the original definition;

// Three - index.php
echo "<h3>Three</h3>";
foreach ($tags as $key => $value) {
  $$key = $value;
}
include "user-info-3.php";

Continue to add the above code to "index.php", then create "user-info-3.php" in the same directory and add the following code;

<?php
// 3 - user-info-3.php
echo "<p>name: {$name}</p>";
echo "<p>blog: {$blog}</p>";
echo "<p>afdian: {$afdian}</p>";

Continue to improve:

// Four - index.php
echo "<h3>Four</h3>";
foreach ($tags as $key => $value) {
  $$key = $value;
}
include "user-info-4.php";

Note that all the code written in "index.php" or "user-info-3.php" above is within <?php;

Little knowledge: For PHP syntax, remember <?php ?>, when there is no need to close in the middle to insert HTML, the ending ?> used to end can be omitted;

The code for the "user-info-4.php" file below is mainly in HTML, and PHP syntax is only used in the variable output part;

<!-- 4 - user-info-4.php -->
<p>name: <?php echo $name; ?></p>
<p>blog: <?php echo $blog; ?></p>
<p>afdian: <?php echo $afdian; ?></p>

In a sense, the code and mechanism represented by the three comments // Data for display - index.php, // Four - index.php, and  constitute a simple template syntax implementation;

However, inserting PHP syntax into HTML is still not very convenient, and in fact, the code in the  part is converted from the following code:

 <!-- 4 - user-info-4.php -->
<p>name: {$name}</p>
<p>blog: {$blog}</p>
<p>afdian: {$afdian}</p>

↑ This is also the "template tag" syntax adopted by Z-BlogPHP;
