What are some common mistakes that PHP beginners make when using str_ireplace for text manipulation?

One common mistake beginners make when using str_ireplace for text manipulation in PHP is not providing the correct parameters. The function requires three parameters: the search string, the replacement string, and the input string. Another mistake is not assigning the result of str_ireplace back to a variable, as the function does not modify the input string in place. To solve these issues, make sure to provide all three parameters in the correct order and assign the result to a variable. 

// Incorrect usage
$str = "Hello World!";
str_ireplace("hello", "hi", $str); // Missing assignment of result

// Corrected code
$str = "Hello World!";
$new_str = str_ireplace("hello", "hi", $str);
echo $new_str; // Output: "hi World!"
