there's a page i've been tinkering with, off and on, to teach myself
php. it's a cryptogram page:
http://www.dirac.org/p/crypto/index.php
i have some data that i pass using hidden form fields, like this:
print "<FORM action=\"index.php\" method=\"post\">\n";
print "<INPUT type=\"hidden\" name=\"PlainText\" value=\"$PlainText\">\n";
print "<INPUT type=\"hidden\" name=\"CipherText\" value=\"$CipherText\">\n";
when the user presses the submit button, any apostrophes or backslashes
within $PlainText or $CipherText get backslashed. Like this:
before pressing submit:
TO TEST A MAN'S CHARACTER,
1st time submit is pressed:
TO TEST A MAN\'S CHARACTER,
2st time submit is pressed:
TO TEST A MAN\\'S CHARACTER,
and so on. i'm not sure why or how the backslashes are entering the
string. without really knowing why this is happening, i tried to remove
the symptom by brute force:
$PlainText = ereg_replace('\\([[:punct:]])', \\1, $PlainText);
$CipherText = ereg_replace('\\([[:punct:]])', \\1, $CipherText);
but php didn't like the backslashes.
i'm kind of lost. any ideas?
