Why is the sentence in the middle "Therefore, we can change the code for question 1 just now to:" displayed?
<?php
$shixi = 'Study hard for four years in college<br />';
$buran = 'Otherwise there will be no chance of internship<br />';
$mimang = 'Use others’ time to be confused Get PHP Chinese website<br />';
##$xuexi = 'Learn PHP<br />';
//We can splice all the strings together.
echo $shixi . $buran . $mimang . $xuexi;
?>
So, the question just now is We can change the code to:
<?php
$php = 'PHP Chinese website';
//A space is added in the middle
$str = $php . 'aaaa';
echo $str;
?>
