Question

Consider the following code for printing questions from text file:

    foreach ($lines as $line_num => $line) {
        if($line_num%3 == 1){
            echo 'Question '.$count.':'.'<br/>'.'<input type="text" value="$line" class="tcs"/>'.'<br/>';

I’ve tried many string escaping combinations. The problem is that I get $line inside the text field instead of the variable value. Any help is greatly appreciated.

Answer 1

Remove the variable from the ' quoted string, or use " so the variable is interpreted.

echo 'Question ' . $count . ':<br/><input type="text" value="' . $line . '" class="tcs"/><br/>';

or

echo "Question " . $count . ":<br/><input type=\"text\" value=\"$line\" class=\"tcs\"/><br/>";

The first option is better, since you don’t have to escape anything else.
