How do you encode a string to HTML entities in PHP With Example?

Hello Friends Today, through this tutorial, I will tell you How do you encode HTML entities in a string using the in PHP With Example? In PHP, you can encode a string to HTML entities using the `htmlspecialchars()` function. This function converts special characters to their respective HTML entity equivalents. Here’s an example:

<?php
// Example string to encode
$string = '<b>Hello</b>, "world" & special characters: < > &';
// Encode the string to HTML entities
$encoded_string = htmlspecialchars($string, ENT_QUOTES);
// Output encoded string
echo "Original string: $string <br>";
echo "Encoded string: $encoded_string";
?>

In this example:

1. We have a string `$string` that contains special characters like `<`, `>`, `&`, and quotes (`”`).
2. We use the `htmlspecialchars()` function to encode these special characters.
3. The second parameter `ENT_QUOTES` tells the function to convert both double and single quotes.
4. The encoded string is stored in the variable `$encoded_string`.
5. We then output both the original and encoded strings using `echo`.

Output:

Original string: <b>Hello</b>, "world" & special characters: < > &
Encoded string: &lt;b&gt;Hello&lt;/b&gt;, &quot;world&quot; &amp; special characters: &lt; &gt; &amp;

As you can see, the special characters in the original string have been encoded to their respective HTML entities in the encoded string.
