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!
Full Version: compare strings?
| HTML |
| [Email Removed] <br> [Email Removed] was passed<br> not yet!<br> |
[PHP]
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";
}
[/PHP]

They're not the same - $buffer ends in a newline char.
try
if (trim($buffer)==$email){
although that does not allow for capitalization.

C.
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.
