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.
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.
Did you try:
echo 'Question ' . $count . ':'.'<br/>'.'<input type="text" value="' . $line . '" class="tcs"/>'.'<br/>';
Variables don't get processed in single quoted strings. You need to use double quotes or another way of inserting them (such as concatenation).
