  2. Hi!
    I want to replace first character of string with last character whatever it is.
    Let say, I have a string:

    $string="0123456";

    I want it to be like this;
    $string="612345";
    and then
    "51234"
    and then
    "4123" and so on.
    How I can do that in php. I am new to php.Thanks

  3. I needed this to construct a complicated MySQL query where the data input had to be really flexible, and the first character of the search term may or may not be available. This trick worked like a charm by letting me try the search with or without the first character. Thanks!

  4. To give an answer to the comment of Anonymous:

    You can replace the first letter of a string by treating the string like an array with each letter being a key of the array. Counting in strings starts at 0. So in order to replace the first letter, you simply do this:

    $string = "abcdef";
    $string[0] = "g";
    echo $string; // will output "gbcdef"

  5. Also you can try the following:
    echo "z".substr($my_text,1,strlen($my_text)-1);
