顯示結(jié)果的第一個(gè) IF 語(yǔ)句的結(jié)果。我想使用兩個(gè)輸出值來(lái)操作第二個(gè)IF語(yǔ)句，以獲取的值，或者在任何給定時(shí)間只有一個(gè)返回值。我嘗試過(guò)在每個(gè) if 或 ifelse 語(yǔ)句中使用，但無(wú)濟(jì)于事。有人可以提供幫助嗎？$loadedWeightUSTons$emptyWeight$loadWeightUSTons or $emptyWeight第一中頻統(tǒng)計(jì)if ($loadWeightUSTons == 0) { echo "E"; }else { echo "L"; } echo "</td>"; echo "<td>"; if ($loadWeightUSTons == 0){ $emptyWeight = "Not Found!"; foreach($railunit->railUnit as $ru) { if((string)$ru->rvXMLfilename == $rvXMLfilename){ $emptyWeight = (string)$ru->unitWeight; } } echo $emptyWeight; }else{ echo $loadWeightUSTons; }第二中頻統(tǒng)計(jì)if ($loadWeightUSTons <= 10) { echo "X"; } elseif ($loadWeightUSTons <= 20){ echo "XX"; } elseif ($loadWeightUSTons <= 30){ echo "XXX"; } elseif ($loadWeightUSTons <= 40){ echo "XXXX"; } elseif ($loadWeightUSTons <= 50){ echo "XXXXX"; } elseif ($loadWeightUSTons <= 60){ echo "XXXXXX"; } elseif ($loadWeightUSTons <= 70){ echo "XXXXXXX"; } elseif ($loadWeightUSTons <= 80){ echo "XXXXXXX"; } elseif ($loadWeightUSTons <= 90){ echo "XXXXXXXX"; } elseif ($loadWeightUSTons <= 100){ echo "XXXXXXXXX"; } elseif ($loadWeightUSTons <= 110){ echo "XXXXXXXXXX"; } elseif ($loadWeightUSTons <= 120){ echo "XXXXXXXXXXX"; } elseif ($loadWeightUSTons <= 130){ echo "XXXXXXXXXXXX"; } elseif ($loadWeightUSTons <= 140){ echo "XXXXXXXXXXXXX"; } elseif ($loadWeightUSTons <= 150){ echo "XXXXXXXXXXXXXX"; } else{ echo "Error!"; }

我最終接受了上面的建議，并將其應(yīng)用于下面看到的IF語(yǔ)句。它取代了笨重的聲明。ifelseif
if ($loadWeightUSTons == 0){
echo str_repeat('X', ceil($emptyWeight/10));
}else{
echo str_repeat('X', ceil($loadWeightUSTons/10));
}

if ($loadWeightUSTons > 150) {
echo "Error!";
} else {
echo str_repeat("X",ceil($loadWeightUSTons/10));
}
但我可能會(huì)建議只按原樣輸出數(shù)字。擁有這些并不比數(shù)字更能提供信息。這將帶來(lái)更好的用戶體驗(yàn)。特別是如果你將這個(gè)數(shù)字限制在150，并且你有像那里這樣的長(zhǎng)數(shù)字值。XXX1 234 567 890
