The strip_tags function in PHP is used to filter out HTML and PHP tags from a string. It removes all HTML tags and PHP codes, leaving only plain text content. This helps to prevent users from inputting malicious code or HTML tags, and is used to sanitize data submitted by users to ensure safety.<\/p>\n

Here is the basic syntax of the strip_tags function:<\/p>\n

string strip_tags ( string $str [, string $allowable_tags ] )\r\n<\/code><\/pre>\n
    \n
  1. $str: a string that needs to have tag filtering.<\/li>\n
  2. $allowable_tags: Optional parameter specifies which tags are allowed to remain, while all other tags will be removed.<\/li>\n<\/ol>\n
    The strip_tags function converts a string that contains HTML or PHP tags into plain text, removing all tags. For example, if you are retrieving data from a user input form field and want to display this data without any HTML tags, you can use the strip_tags function to clean up the data from any tags.<\/p>\n
    It is important to note that the strip_tags function may not be suitable for all situations, as it simply removes tags without more advanced filtering or validation. When dealing with user input, carefully choose the appropriate method to ensure security based on specific needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
