str_ireplace() function will automatically find the STRING EITHER IN UPPER OR LOWER CASE … CONFUSEEEE

$find1 array variable contain all the value in lower case and may be user enter the value either in upper or lower … so we have one solution either we can use strtolower() function to convert the user entered string in to lower… but what happen it will convert all the content into lower case …
So here str_ireplace() function came into the picture… str_ireplace function will check the user entered data contain any word which match to $find1 array variable value… If yes then check that value entered by user is in capital .. then only that work will convert into the lower form…

str_ireplce() is kind of magic function which will automatically understand the lower and upper value itself and then replace it …
