This simple example:

<?php
$str=" now, after all the spaces some text";
echo $str;
?>

prints:

now, after all the spaces some text


However, I want to preserve white space, so it prints the leading spaces.

now, after all the spaces some text

Can anyone suggest how to do it?

My actual program (rather than that simple example) prints stdout from
an executable program after the output is opened with popen, read with
fgets and printed with echo - see below. But I think the problem is the
same as in the above simpler code.

<?php

$cmd=$_POST['input_data']; // Read from a form.

$handle = popen("echo $cmd | /usr/local/bin/math" , "r");
$data=fgets($handle);
echo "$data<br>";
?>
