我试图用单一陶器的ach子来补充两个阵列的所有变量。 一些编码实例将获得荣誉。
我有:
<?php
foreach($menu_names as $menu_name){
echo "<li><a href= ?subj= " .urlencode($subjects["id"]). " >".$menu_name."</a></li>";
}
?>
我想在这个大厅内再增加一个阵列。

假设这两个阵列中的项目数目相同。
if you want to use foreach()
, then the arrays need to have the same index:
foreach ($a as $index => $value)
{
echo $a[$index] . . $b[$index];
}
如果阵列有数字指数,你只能使用<代码>(>):
for ($i = 0; $i < sizeof($a); $i++)
{
echo $a[$i] . . $b[$i];
}
array_combine()
will merge your 2 arrays into one with key=>value
pairs and then access them through foreach statement
e.g
foreach(array_combine($a,$b) as $key=>$value) {
echo $key."<br/>".$value;
}
答案取决于实际。 你们需要与阵列和你们需要怎样做。
如果贵国的阵列有类似的指数,而且你需要使用每一阵列中的相同成分,那么你可以这样做。
foreach ($array1 as $index => $value1) {
$value2 = $array2[$index];
// do stuff with $value1 and $value2 here
}
(尽管在此情况下,特别是如果你发现自己做了很多工作,你可能想使用单一系列的物体或阵列,以便数据始终齐头并易于连接。)
或者,如果这些阵列有相同类型的内容,而且你希望对这两者进行重复,你就可以在<条码>上重复(第1款,第1款,第2款)代码>。 (如果阵列在数字上加以指数化,但特别是如果它们具有同样的强力,则阵列要素之一可以取代。) See the docs on array_joint
for details.
还有其他一些可能性,取决于你们如何需要这些要素。 (问题确实没有为此提供任何信息)。

<?php
$First = array( a , b , c , d );
$Second = array( 1 , 2 , 3 , 4 );
foreach($First as $indx => $value) {
echo $First[$indx].$Second[$indx];
echo "<br />";
}
?>
或
<?php
$First = array( a , b , c , d );
$Second = array( 1 , 2 , 3 , 4 );
for ($indx = 0 ; $indx < count($First); $indx ++) {
echo $First[$indx] . $Second[$indx];
echo "<br />";
}
?>
