如何去除PHP日期中1-9数字的前导零？

嗨，这个问题很容易解决，核心是调整PHP date() 函数里的格式参数就行！你现在用的d和m会返回带前导零的日期和月份，换成对应的无零格式参数就搞定了：

• 把日期的date("d", time())改成date("j", time())：j 参数会返回1-31的日期数字，没有前导零
• 把月份的date("m", time())改成date("n", time())：n 参数会返回1-12的月份数字，没有前导零

修改后的完整代码如下：

//Note : I change to Indonesian Format date.
$hari = array ("Minggu","Senin","Selasa","Rabu","Kamis","Jumat","Sabtu");
$bulan = array ("Januari","Februari","Maret","April","Mei","Juni","Juli","Agustus","September","Oktober","November","Desember");
$waktu[0]=$hari[date("w",time())];
$waktu[1]=date("j",time()); // 替换d为j，去除日期前导零
$waktu[2]=date("n",time()); // 替换m为n，去除月份数字前导零
$waktu[3]=date("Y",time());
$waktu[4]=date("H",time());
$waktu[5]=date("i",time());
$waktu[6]=date("s",time());
$hariini="$waktu[0]";
$tanggalini="$waktu[1] ".$bulan[$waktu[2]-1]." $waktu[3]";
$jamini="$waktu[4]:$waktu[5]:$waktu[6]";
$today = $waktu[0].", ".$tanggalini;
echo $today;

运行这段代码后，结果就会变成Kamis, 1 Februari 2018，完美去掉了日期的前导零~ 而且因为n返回的是1-12的数字，减1后依然能正确匹配$bulan数组的索引，完全不影响印尼语月份的显示效果。
