Remove Text in a String with PHP

You can remove any text, like asterisks (*), for example, from a string using the str_replace() function. Here’s an example:

<?php
$string = 'Hello, *world*!';
$clean_string = str_replace('*', '', $string);
echo $clean_string;
?>

Here, we use the $string variable to store the original string that contains asterisks. We then use the str_replace() function to replace all occurrences of the asterisk character with an empty string, effectively removing them from the string. The first argument to the function is the string to search for (* in this case), the second argument is the string to replace it with (an empty string ''), and the third argument is the original string to modify.

Now, we use the echo statement to output the cleaned string. In this example, the output would be “Hello, world!” with the asterisks removed.

You can also use regular expressions with the preg_replace() function to remove asterisks from a string. Like this:

<?php
$string = 'Hello, *world*!';
$clean_string = preg_replace('/\*/', '', $string);
echo $clean_string;
?>

In this example, we use a regular expression (/\*/) to match any asterisks in the string and replace them with an empty string using preg_replace(). The result is the same as with str_replace().
