使用字符串的案例/开关

Question

I have this weather script that and I'm trying to display a different image for every weather condition (case), the image will also be different if it's day or night.

Here is what I'm doing...

GETTING THE XML Info. into .PHP

    <?php
    $CapDCityANDState = "Atlanta, GA";
    $url="https://www.google.com/ig/api?weather=$CapDCityANDState&hl=en&referrer=googlecalendar";

    $xml = simplexml_load_file($url);

    //print_r($xml);

    //echo "Test: " . $xml->current_conditions->temp_f['data'];
    $DayNow = date(D);
    $DayTomorrow = date('D', strtotime('+1 day'));
    $DayAfterTomorrow = date('D', strtotime('+2 day'));
    $DayAfterAfterTomorrow = date('D', strtotime('+3 day'));


    $CurrentTxt = $xml->weather->current_conditions->condition->attributes()->data;
    $CurrentTemp = $xml->weather->current_conditions->temp_f->attributes()->data;
    //echo $CurrentTemp[0];

    echo("<BR><BR>");

    $DayOneLow = $xml->weather->forecast_conditions[0]->low->attributes()->data;
    $DayOneHi = $xml->weather->forecast_conditions[0]->high->attributes()->data;
    $DayOneTxt = $xml->weather->forecast_conditions[0]->condition->attributes()->data;
    //echo $DayOneLow[0];

    $DayTwoLow = $xml->weather->forecast_conditions[1]->low->attributes()->data;
    $DayTwoHi = $xml->weather->forecast_conditions[1]->high->attributes()->data;
    $DayTwoTxt = $xml->weather->forecast_conditions[1]->condition->attributes()->data;
    //echo $DayTwoLow[0];


    $DayTriLow = $xml->weather->forecast_conditions[2]->low->attributes()->data;
    $DayTriHi = $xml->weather->forecast_conditions[2]->high->attributes()->data;
    $DayTriTxt = $xml->weather->forecast_conditions[2]->condition->attributes()->data;
    //echo $DayTriLow[0];


    $DayFourLow = $xml->weather->forecast_conditions[3]->low->attributes()->data;
    $DayFourHi = $xml->weather->forecast_conditions[3]->high->attributes()->data;
    $DayFourTxt = $xml->weather->forecast_conditions[3]->condition->attributes()->data;
    //echo $DayFourLow[0];


    ?>

DISPLAY WEATHER FORCAST INFO.

<div>Currently: <?php echo $CurrentTemp[0]; ?>&deg; - <?php echo $CurrentTxt[0]; ?> - H: <?php echo $DayOneHi[0]; ?>&deg; L: <?php echo $DayOneLow[0]; ?>&deg; - Rest of the Day: <?php echo $DayOneTxt[0]; ?></div>
            <div><?php echo($DayTomorrow);?>: <?php echo $DayTwoHi[0]; ?>&deg;/<?php echo $DayTwoLow[0]; ?>&deg; - <?php echo $DayTwoTxt[0]; ?></div>
            <div><?php echo($DayAfterTomorrow);?>: <?php echo $DayTriHi[0]; ?>&deg;/<?php echo $DayTriLow[0]; ?>&deg; - <?php echo $DayTriTxt[0]; ?></div>
            <div><?php echo($DayAfterAfterTomorrow);?>: <?php echo $DayFourHi[0]; ?>&deg;/<?php echo $DayFourLow[0]; ?>&deg; - <?php echo $DayFourTxt[0]; ?></div>

<br>

FINDOUT IS IT DAY OR NITE CURRENTLY

<?php
$img = time() > $sunriseTime && time() < $sunsetTime ? 'day' : 'nite';
// $img <-- will say 'day' if it's day and 'nite' if its nite
?>

GET WHAT IMAGE TO SHOW DEPENDING IF IT'S DAY OR NITE AND ALSO GET THE WEATHER CONDITION TEXT AND BASE THE IMAGE ON THOSE TWO FACTORS.

<?php

if ($img == "day"){
// START OF DAY
switch ($DayOneTxt[0]) {

SHOW WHAT IMAGE NAME TO USE e.g. "32.png"

<?php echo($WeatherIMG); ?>

The image always shows "1.png" and that is wrong :(

Answer 1

<?php
$txtDay = Array( "clear"=>1, "sunny"=>2, "partly cloudy"=>3, "mostly cloudy"=>4, "haze"=>5, "fog"=>5, "dust"=>5, ............. "scatter snow showers"=>43);
$txtNight = Array( "clear"=>1, "sunny"=>2, "partly cloudy"=>3, "mostly cloudy"=>4, "haze"=>5, "fog"=>5, "dust"=>5, ............. "scatter snow showers"=>43);
if ($img == "day"){
    $imgWeather = $txtDay[{$DayOneTxt[0]}] . ".png";
} else {
    $imgWeather = $txtNight[{$DayOneTxt[0]}] . ".png";
}
?>
