特殊字符的str_replace

Question

$fetched_column['title'] = str_replace(' ', '<SP>', $fetched_column['title']);

echo $fetched_column['title'] . '<br>';

When it echos out it strips the white_space but doesn't replace it with <SP> . I'm guessing because of the < > . Don't know how to fix this so it echos out <SP> in replace of the white_space?

Answer 1

If you see view-source you can see your replaced code but because HTML tries to parse it as something (eg. directive), you dont see it in parsed web view.

You can use html entities for exactly that reason.

code would be:

$fetched_column['title'] = str_replace(' ', '<SP>', $fetched_column['title']);

echo $fetched_column['title'] . '<br>';

Answer 2

You need to use htmlspecialchars() or htmlentities() function to make it display into < and > . Technically it shouldn't be <SP> , but instead <SP> .

Change your code to:

echo htmlentities($fetched_column['title']) . '<br>';

Or you can do it in the first attempt, when you are trying to replace, as the correct format:

$fetched_column['title'] = str_replace(' ', '<SP>', $fetched_column['title']);
