I have this PHP code that works:
for ($i=0; $i < 5; $i++) {
do stuff to $class
echo "<i class=\"glyphicon glyphicon-star $class\"></i>";
}
Instead of using echo in the loop, how would I append each iteration to a variable (say $stars) and then be able to display the result with
echo "$stars";
Create a variable to hold your HTML. Concatenate the HTML to this variable instead of echoing it.
After the loop you can echo that variable.
$stars = '';
for ($i=0; $i < 5; $i++) {
// do stuff to $class
$stars .= "<i class=\"glyphicon glyphicon-star $class\"></i>";
}
echo $stars;
You can use Concatenation assignment .= like this
$var='';
for ($i=0; $i < 5; $i++) {
do stuff to $class
$var.="<i class=\"glyphicon glyphicon-star $class\"></i>";
}
echo $var;
Alternatively, you can do this without modifying your existing code using output buffering.
// start a new output buffer
ob_start();
for ($i=0; $i < 5; $i++) {
//do stuff to $class
// results of these echo statements go to the buffer instead of immediately displaying
echo "<i class=\"glyphicon glyphicon-star $class\"></i>";
}
// get the buffer contents
$stars = ob_get_clean();
For a simple thing like this I would still use concatenation with .= as shown in the other answers, but just FYI.
echo=>$stars.=echo $stars;has the same effect asecho "$stars";. The double quotes aren't necessary.
