PHP Escaping 数组内字符串中的特殊字符

Question

I'm trying to load all my preg_replace requirements into an array. They're a bit complicated, since they're all regular expressions and XML tags.

This is the way the plain preg_replace is:

$content = preg_replace('/\<MESSAGE(.*?)>/im','<MESSAGE>',$content);

I'm trying to do:

$stripData = array( '/\<MESSAGE(.*?)>/im','<MESSAGE>', )

But when I do print_r($stripData), I get Array ( [/\/im] => )

What's happening here? Certain parts are not included in the array string at all.

I was expecting to get print_r as Array ( [/\<MESSAGE(.*?)>/im] => <MESSAGE>)

Answer 1

The problem you're reporting is related with the browser parsing the <MESSAGE(.*?)> as an HTML tag. My comment is correct about specifying the problem, but the using of <pre> tag is wrong as it won't solve the problem. The solution is encoding the array string using htmlentities method like this:

echo htmlentities(print_r($stripData, 1));

This will produce the following result:

Array
(
    [0] => /\<MESSAGE(.*?)>/im
    [1] => <MESSAGE>
)

Which will be visible on the browser like this:

Array ( [0] => /\<MESSAGE(.*?)>/im [1] => <MESSAGE> )

Answer 2

Simply by using htmlentities function:

htmlentities(print_r($stripData, true));
