If the keys to both arrays are always in parity, you could do something like

<pre><code>foreach ($a as $key =&gt; $value) {
 $newArray[] = "$value','{$b[$key]}";
}

var_dump($newArray);
// would output the below
array(3) {
[0]=&gt;
 string(5) "a','1"
 [1]=&gt;
 string(5) "b','2"
 [2]=&gt;
 string(5) "c','3"
</code></pre>

However, the result looks a little weird, are you sure this is what you are trying to achieve?

$b=array("1","2","3");

if(count($a)+>+count($b)){

}

Use above code it will for your array.

<pre><code>$c = array_map(function ($a, $b) { return "$a','$b"; }, $a, $b);
</code></pre>

For whatever that's good for...

blocks|key|3328325|text|使用SPL的MultipleIterator：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3328326|$a+=+array("a","b","c");
$b+=+array("1","2","3");

$mi+=+new+MultipleIterator();
$mi->attachIterator(new+ArrayIterator($a));
$mi->attachIterator(new+ArrayIterator($b));

$c+=+array();
foreach($mi+as+$row)+{
++++$c[]+=+$row[0]+.+"','"+.+$row[1];
}

var_dump($c);|code-block|syntax|javascript|3328327|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Using SPL's MultipleIterator:

<pre><code>$a = array("a","b","c");
$b = array("1","2","3");

$mi = new MultipleIterator();
$mi-&gt;attachIterator(new ArrayIterator($a));
$mi-&gt;attachIterator(new ArrayIterator($b));

$c = array();
foreach($mi as $row) {
 $c[] = $row[0] . "','" . $row[1];
}

var_dump($c);
</code></pre>

Here is an example...

I have the following code:

<pre><code>$a=array("a","b","c");
$b=array("1","2","3");

$c = array_merge($a,$b);

echo "&lt;pre&gt;";
var_dump($c); 
echo "&lt;/pre&gt;";
</code></pre>

Gives me an output:

<pre><code>array(6) {
 [0]=&gt;
 string(1) "a"
 [1]=&gt;
 string(1) "b"
 [2]=&gt;
 string(1) "c"
 [3]=&gt;
 string(1) "1"
 [4]=&gt;
 string(1) "2"
 [5]=&gt;
 string(1) "3"
}
</code></pre>

How could I change the code so that it gives me this output instead:

<pre><code>array(3) {
 [0]=&gt;
 string(5) "a','1"
 [1]=&gt;
 string(5) "b','2"
 [2]=&gt;
 string(5) "c','3"
</code></pre>

Any ideas?

Merge arrays. Second array as a "column"
