php array ignoring values

Post by kewpe20 »

I have created the following array.
$a_random = array( '<random-all>', '<random>', '<random-all-or>', '<random-1>',
'<random-all-1>','<random-all-2>','<random-all-3>','<random-all-4>','<random-all-5>','<random-all-6>',
'<random-all-7>','<random-all-8>','<random-all-9>','<random-all-10>',
'<random-or-1>','<random-or-2>','<random-or-3>','<random-or-4>','<random-or-5>','<random-or-6>',
'<random-or-7>','<random-or-8>','<random-or-9>','<random-or-10>'
);

However, when I print_r the array none of the values have been inserted into the array.
It has to do with the '<' '>' characters.
I need those specific values with the '<' '>' to be in the array. How can I force the array to populate them?

It is creating the array with < and > but your browser interprets them as HTML tags just like <body> etc, so it doesn't display them. Do a view source on your browser and you will see them. You need to convert them to the HTML entities for the browser to display them. You could probably do this:

Code: Select all

print_r(array_map('htmlentities', $a_random));

That makes sense but it is making it very difficult to trouble shoot an issue I'm having.
The code that follows is behaving like the array is empty. That's why I assumed the array was really empty.

Make your own function to do this and also save typing. I would also wrap it in pre tags so that you get it nicely formatted in the browser(tabs, newlines, etc.):

Code: Select all

function pre($var) {
    echo '<pre>';
    print_r(array_map('htmlentities', $var));
    echo '</pre>';
}
