ThinkPHP is an open source PHP framework. It provides very rich functions and powerful extension mechanisms, and is widely loved by PHP programmers. Among them, ThinkPHP's template engine is one of its core functions and supports a variety of template syntaxes, of which square bracket writing is a very commonly used one.

The square bracket writing method refers to using {$variable} in the template file to output the value of the variable. In this writing method, a mechanism called "ordinary variable parsing" is used, which will replace all variables that conform to the square bracket writing format with the corresponding PHP code.

For example, in the template file, we can write like this:

<h1>Hello, {$name}!</h1>
Copy after login

Here {$name} is a variable, which represents dynamic content. At runtime, the template engine will replace it with a PHP variable:

<h1>Hello, <?php echo ($name); ?>!</h1>
Copy after login

In this way, the value of the variable name can be dynamically output.

In addition to ordinary variable parsing, square brackets can also be used in nested formats to represent complex data types such as arrays and objects. For example:

<ul>
    {foreach $users as $user}
    <li>
        {$user['name']},{$user['age']}岁,来自{$user['address']['city']}。
    </li>
    {/foreach}
</ul>
Copy after login

In this code, we use the {foreach} tag and the $users array, here the variable .name , .age, .address.city, all use square brackets to get the value of the corresponding attribute.

In general, square bracket writing is a very practical feature in ThinkPHP, which allows us to easily output variable values ​​and also helps us deal with more complex data types. If you haven't used this method of writing yet, you might as well try it the next time you write a template file.
