This is accomplished using such tools as strcmp() which is a built-in to PHP. <?php Function chk_passwds($input1, $input2) { if (strcomp($input1, $input2) = 0) { print "Passwords are equal, proceed<br>"; }else { print "Passwords are not equal<br>"; } } chk_passwds("doggy1", "Doggy1"); // strcmp is case-sensitive and thus these passwords are not equal ?> The strcomp() function has three possible results: 0 means the two strings are equal, -1 means that the first string is less than the second string and 1 means that the second string is less than the first string.
