Escape character

I have this function :

<?php
function getmypost($number)
    {
        query_posts('p=1828');
        while (have_posts()) : the_post();
        the_title('<h1>', '</h1>开发者_StackOverflow中文版;');
        the_content();
        endwhile;
    }
?>

I need to make the 1828 as a variable I have tried this:

    query_posts('\'p='. $number .'\'');

But it does not work. What would be the right way to do this?

If I understand you correctly

query_posts('p='.$number);

should work.

If you need a single quote ' in the string you'd escape the '

query_posts('p=\''.$number.'\'');

or using double quotes (more elegant, and you can put the variable straight in. Dominik already suggested this in his answer)

query_posts("p='$number'");

You could use

query_posts("'p=$number'");
