我有以下if语句,这些语句收集了在显示之前选定的所有日期。
$daysUsed = "";
if($this->dayweeksunsession==1){
$daysUsed .= "Su ";
}
if($this->dayweekmonsession==1){
$daysUsed .= "M ";
}
if($this->dayweektuessession==1){
$daysUsed .= "T ";
}
if($this->dayweekwedsession==1){
$daysUsed .= "W ";
}
if($this->dayweekthurssession==1){
$daysUsed .= "Th ";
}
if($this->dayweekfrisession==1){
$daysUsed .= "F ";
}
if($this->dayweeksatsession==1){
$daysUsed .= "Sa ";
}
if($daysUsed !=="") {
echo "</span><br/>Days of the Week: <span class='BoxReviewOutput'>";
echo $daysUsed;
}
我的问题是,我怎样才能做到这一点,以便除最后一天外,每周的每一天都显示逗号。
例如:选择星期日和星期二。所以会显示“Su,T”
提前谢谢!
最佳答案
在ifs中添加一个逗号:
$daysUsed = "Whatever, ";
然后在输出最后一个字符串之前:
$daysUsed = substr($daysUsed, 0, -2);
编辑:-1必须是-2,以说明两天之间的间隔。
关于php - 除最后一个日期外,其他日期以逗号显示,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/10111579/
