The
strip_tags() function in PHP will strip tags from a string. You can use one or two parameters with this function. Using only one parameter it will strip all tags found in a string. Using the second parameter will allow you to specify tags that should not get stripped from the input string.
<?php
$myString = "<strong><em>Hello World</em></strong>";
$stripResult1 = strip_tags($myString);
echo $stripResult1;
// Returns "Hello World"
echo "<br />";
$stripResult2 = strip_tags($myString, "<strong>");
echo $stripResult2;
// Returns "<strong>Hello World</strong>"
?>
Hello World
Hello World
In the second result you can see that we stripped all tags except the <strong> tags in the string by specifying a second parameter. Using only one parameter in the first result stripped all tags.
