Question

If I have a simple code like this:

$a = "hi";

for ($i = 0; $i < 3; $i++)
{
    echo $a;
}

so the output will be hihihi , is it possible to convert it into a string such as $b="hihihi" without through the loop anymore?
I’m using it for other function.

Answer 1

I’ll assume that your situation is a little more complicated than the example given…

One option would be to not echo your variables to the buffer. Instead, append them to your own variable:

$out = '';
for ($i = 0; $i < 3; ++$i) {
    $out .= 'hi';
}

echo $out; // "hihihi"

However, if, for whatever reason the echoing is not happening in code that you have control over, you could use output buffering.

ob_start();
for ($i = 0; $i < 3; ++$i) {
    doSomethingWhichPrintsHi();
}
$out = ob_get_clean();  // "hihihi"
