php uses regular matching to remove html as follows:
First define a string containing HTML tags.
$html_string = "<div><h2>Hello World</h2><p>This is <strong>P HP</strong>.</p></div>";
The above code defines a string with standard HTML tags. Our goal is to remove all HTML markup and leave only plain text content.
Use the preg_replace() function to remove all HTML tags in the string.
The following code demonstrates how to use the preg_replace() function to remove HTML tags.
$plain_text = preg_replace('/<[^<]+>/', '', $html_string);echo $plain_text;
In the above code, we define a preg_replace() function with a regular expression pattern. The regular expression pattern `
/<[^<]+>/
` means to find any substring starting with "<" and ending with ">" and replacing it with an empty string. This will remove all HTML tags.
Finally, we can output a string that does not contain HTML tags on the screen.
