hi all,

how to delete special characters and symbols in user given string .

actually I'm getting the data from user input type as text area has string in my php file and separating the string into separate words when space is there in the string and storing the words as array . if any word contains special characters then it has remove the special characters it hasstore only words without special characters.

You could use an aray of characters to replace:

$find = Array('$','£','.',';');    // use whatever characters you want to remove here
$replace = Array('', '', '', '');    // should contain the same amount of elements as $find

$newString = str_replace($find, $replace, $string);

You can use this before or after you split the string into an array of words, although it is best doing it before as you won't end up with empty array elements and it is a lot more efficient with regards to memory consumption.
