How to set text center alignment effect for PHP array

In Web development, arrays are a very commonly used data structure. Because PHP is a very popular Web programming language, familiarity with PHP arrays is particularly important. When using PHP arrays, we sometimes need to center-align the text in them. This article will introduce how to use PHP arrays to set text center alignment.

1. Using PHP arrays

In PHP, an array is a set of ordered values. We can use simple arrays to store multiple values. Here is a simple PHP array:

$students = array('Tom', 'Jerry', 'Spike', 'Tyke');

In the above example, we have created an array named $students which contains the names of four students. We can access the elements in the array using numeric keys, the first element of the array has the key 0.

2. Center-aligned text in PHP arrays:

By default, text in PHP arrays is left-aligned. If we want to center align the text, we can use the following code:

<?php
$students = array(&#39;Tom&#39;, &#39;Jerry&#39;, &#39;Spike&#39;, &#39;Tyke&#39;);

echo "<table>";
foreach($students as $student) {
    echo "<tr><td align=&#39;center&#39;>" . $student . "</td></tr>";
}
echo "</table>";
?>

In the above code, we have used the HTML <table> element to display the student names. In the foreach loop, we use the <tr> and <td> elements to create a table row and column, <td> The align='center' attribute in the element is used to center align text.

Using the above code, you can easily center align text in a PHP array.

3. Other center alignment methods:

Similar to center alignment, use the following code to achieve right alignment and alignment at both ends:

Right alignment:

echo "<tr><td align=&#39;right&#39;>" . $student . "</td></tr>";

Align both ends:

echo "<tr><td align=&#39;justify&#39;>" . $student . "</td></tr>";

4. Summary
