我有一个变量,用于输出地址的坐标。我正在打印名称之前的坐标以进行测试。在奇数循环(它在foreach循环中)它工作正常,将变量放在data-latLng
属性中。在偶数循环上,它给出了不同的值 - 而不是坐标。值类似于:2
和.
。
这就是我的意思:
奇数编号的循环会打印出来:
同时在偶数循环数上,data-latLng
属性会输出不同的值:
以下是代码:
$area_lat_long = isset($area_lat_long[$mapCounter])?$area_lat_long[$mapCounter]:"-26.2041028, 28.047305100000017";
echo $area_lat_long;
echo '<strong>area: '. $streetAdd[$count] .' <a class="glyphicon glyphicon-new-window" type="button" data-toggle="modal" data-target="#mapModal" data-latLng="'. $area_lat_long .'" style="cursor:pointer;"></a><br>';
$mapCounter++;
PHP代码在表格代码上方运行,上面的代码给出了坐标线,然后是区域。
正如您所看到的,$area_lat_long
在每个区域之前给出坐标,但是当data-latLng
使用EXACT相同的变量时,它会在偶数循环上发生变化吗?
修改 对于那些想要评论中整个循环的人来说:
foreach ($streetAdd as $key){
print_r($area_lat_long);
//LAT LONG
$area_lat_long = isset($area_lat_long[$count])?$area_lat_long[$count]:"-26.2041028, 28.047305100000017";
echo $area_lat_long;
echo '<strong>area: '. $streetAdd[$count] .' <a class="glyphicon glyphicon-new-window" type="button" data-toggle="modal" data-target="#mapModal" data-latLng="'. $area_lat_long .'" style="cursor:pointer;"></a><br>';

答案 0 :(得分:1)
foreach($a as $b) {
$x = isset($x[$c]) ? $x[$c] : "foo7";
echo $x;
}
让我们“运行”那段代码,假设 $ x = array('c'=&gt;'lat,lng'); 在循环之前。
所以循环#1打印'lat,lng'。
循环#2检查isset('lat,lng'[$c])
是否评估为false
,因此$x
将为'foo'
。
'foo'将被打印。
循环#3与#2相同,但检查是否isset('foo'[$c])
,再次评估为false
。
再次打印'foo'。
这就是原因。
我不知道你在那个循环之外做了什么,大多数代码似乎什么也没做,或者意图。
