    $a="XXX"; $a_value=$运算值; $a_txt=$a.$a_vlue; if ($a_value=0){ $a_txt=""; }

    $b="XXX";
$b_value=$运算值;
$b_txt=$a.$a_vlue;
if ($b_value=0){
$b_txt="";
}
..........
$abc=$a_txt.$b_txt.$c_txt...
  • a_txt
  • b_txt
  • a_vlue
  • b_value

    $a_txt = ($a_value !== 0) ? "XXX{$a_value}" : '';

    PHP 比较建议用双引号和{}来做字符串拼接，主要是显而易见。

    $a = 'world';
    $b = "hello {$a}"

    $arr = array('Hello','World!','I','love','Shanghai!');
    echo implode(" ",$arr);
