I tried this but only got a syntax error:
<?php
$a = true;
$str = <<< EOF
{$a ? 1 : 2}
EOF;
echo $str;
Is it possible to use such kind of conditional statement inside heredoc?
Hi,
I have a PHP script that runs database queries. Now, if a query fails, should I trigger an error or throw an exception? I noticed that if I do the latter, the script execution will stop after facing the exception.
My code is as follows:
if (!$this->connection[0]->query($this->query))
throw new Exception($this->connection[0]->error);
What are the pros and cons of using exceptions for this kind of cases (failed queries)?

I am currently building a site and all the books I have read on PHP so far are just on functionality and not much on security. Is there a book that deals specifically with making your code/site secure? I don't want to go public and the next day have all my code changed or my database erased by SQL injection.
thanks
I'm using WordPress as a CMS, and I want to extend one of its classes without having to inherit from another class; i.e. I simply want to "add" more methods to that class:
class A {
function do_a() {
echo 'a';
}
}
then:
function insert_this_function_into_class_A() {
echo 'b';
}
(some way of inserting the latter into A class)
and:
A::insert_this_function_into_class_A(); # b
Is this even possible in tenacious PHP?
Money, Staff, Skill and preference to open source or commercial is neutral. Lets take the best of the best programmers (for arguments sake) and think about this:

Hi,
I have 5 textfields for user input in a form namely:
username1, username2, username3, username4 and username5
I would like to know how should I write my php code such that I will be able to check if there is any duplicates between the 5 textfields during POST?
I can only think of comparing (username1 !== username2) and so on, but I think there should be simpler way to do it right? How should I be able to do it?
Thank you very much.

I sort of want to do:
$rs1 = do_query( "SELECT * FROM animals WHERE type = 'fish'" );
$rs2 = do_query( "SELECT * FROM rs1 WHERE name = 'trout'" );

I am using combination of php+jQuery for captcha validation and later sending mails and do other stuff. The pseudo code is something like this:
captcha_code = jQuery.post(.....execute captcha script and get status)
if(captcha_code == "correct"){
send_mail_using_php_script;
}
Now I have no idea whether spammers can directly execute the "send_mail_using_php_script". Do they? If yes, then shall I move captcha validation in send_mail_using_php_script to make it more safer? Is there any other safer method?
