Related introduction:
strip_tags() function strips HTML, XML and PHP tags in strings.
str_replace() function replaces some characters in a string (case sensitive).
This function must follow the following rules:
If the searched string is an array, then it will return an array. If the string being searched is an array, then it will find and replace each element in the array. If an array needs to be searched and replaced at the same time, and the elements to be replaced are less than the number of elements found, the excess elements will be replaced with empty strings. If you search an array and replace only one string, the replacement string will apply to all found values.
Note: This function is case-sensitive. Please use the str_ireplace() function to perform a case-insensitive search.
Note: This function is binary safe.
