Re: Modifying a String

http://www.php.net/strings
You can do either basic string searching with strpos(), or you can use
regular expressions.

// -------------
// Method 1
// -------------
$str = 'This is MyString and it will be altered';
$find = 'MyString';
if (strpos($str, $find) {
$newStr = substr($str, strpos($str, $find) + strlen($find));
echo $newStr;
// Output: ' and it will be altered'
} else {
echo 'String not found';
}

// -------------
// Method 2 - Regular Expressions
// -------------
$str = 'This is MyString and it will be altered';
$pattern = '/(mystring)/i';
if (preg_match($pattern, $str, $matches, PREG_OFFSET_CAPTURE)) {
$newStr = substr($str, $matches[0][1] + strlen($matches[0][0]));
echo $newStr;
// output: ' and it will be altered'
} else {
echo 'String not found';
}

I havent tested the above, but its just basic String manipulation, you
shouldnt have any issues modifying it.
Best of luck with it.
