Hi, I want to compare two Strings and I don't know how. Following HTML-Output is the result of the below code. why? The Strings are the same but the if() is false, why? Thank you! HTML Code: net <br> net was passed <br> not yet! <br> PHP Code: echo  $buffer . "<br>\n" ; echo  $email . " was passed<br>\n" ; if ( $buffer == $email ) { echo  "string already exists!<br>\n" ; return  true ; } else { echo  "not yet!<br>\n" ; } ...

    Default compare strings?

    Hi,

    I want to compare two Strings and I don't know how. Following HTML-Output is
    the result of the below code. why?
    The Strings are the same but the if() is false, why? Thank you!
    HTML Code:
    net
    <br>
    net was passed<br>
    not yet!<br>
    PHP Code:
    echo $buffer."<br>\n";
    echo 
    $email." was passed<br>\n";
    if (
    $buffer==$email)
    {
    echo 
    "string already exists!<br>\n";
    return 
    true;
    }
    else
    {
    echo 
    "not yet!<br>\n";

    They're not the same - $buffer ends in a newline char.

    try

    if (trim($buffer)==$email){

    although that does not allow for capitalization.

    the eregi function should be what you're looking for.

    eregi($buffer, $email)

    if $email contains $buffer than it will return true. You can also use
    regular expressions. eregi is case insensitive (eg it will interpret 'A'
    and 'a' as the same thing). the ereg function does the same thing only
    it's case sensative.
