re: post/request value in php

& has a special meaning in URLs, it denotes the next parameter. you need to use the %-escape (%26)

re: post/request value in php

what do you mean use the %-escape
is it like this:
<a href='home.php?a=hello%26&world'>hello</a>

re: post/request value in php

tnx i got it.,
<a href='home.php?a=hello%26world'>hello</a>

&amp; would also work, I believe.

Mark.

re: post/request value in php

it won’t in XHTML (and possibly in HTML too), since you must escape the non-entity ampersands.

Of course. Silly me :(

I just happened to read RFC 1738 recently.

re: post/request value in php

how about the apostrophe (') how to escape it.

Don't see where it is in your reference but it's: %27
Have a look here for all the characters.

Just keep in mind, people don't remember characters. Using these characters in URLs is not good for users, unnecessary for URLs, and probably get spiders doing funny things. But that URL encoding reference sheet should give you all the characters you need!
