我有一个包含此数组的数组:
$autos[] = array(
"auto" => "Audi A6",
"Max snelheid" => "240 km/h",
"Verbruik" => "1 op 12");
$autos[] = array(
"auto" => "Porsche 911",
"Max snelheid" => "290 km/h",
"Verbruik" => "1 op 8");
在我的下方,我使用了一个回应这个的foreach。
foreach ($autos as $cars => $arr){
echo '<tr>';
foreach($arr as $test => $data){
echo '<td>'.$data.'</td>';
}
echo '</tr>';
}
当此值为"Verbruik" => "1 op 11"
时,如何回显某些内容?
如果第二个数字高于11,我必须回应#34;那是正确的&#34;。
所以例子是:
$autos[] = array(
"auto" => "Fiat Panda",
"Max snelheid" => "140 km/h",
"Verbruik" => "1 op 11");
所以,当我在上面的代码时。我怎么能回应&#34;那是正确的&#34; ?

使用explode()函数来爆炸你的字符串&#34; 1 op 12&#34;到2个数字的数组,然后检查第二个数字是否大于11或任何你想要的。
foreach ($autos as $cars => $arr){
echo '<tr>';
foreach($arr as $test => $data){
echo '<td>'.$data." ";
if($test == "Verbruik"){
$temp = explode(" op ",$data);
if($temp[1] > 11 ){
echo "correct "; // do whatever you want
}
}
echo '</td>';
}
echo '</tr>';
}

试试这个:
foreach ($autos as $cars => $arr){
echo '<tr>';
foreach($arr as $test => $data){
$numbers = explode(" op ", $data);
if($test == 'Verbruik'){
if((int) $numbers[1] >= 11)
echo '<td>'.$data." , That's correct!</td>";
}
else
echo '<td>'.$data.'</td>';
}
echo '</tr>';
}
