PHP echo array of array within ""

Question

for($i=0;$i<count($some_array);$i++){
   echo "<h3 name=$some_array[2][$i]>$some_array[1][$i]</h3>";      
}

Why doesn't this work? Is it possible to echo a value of an array of an array within "" without using this annoying combining-strings-method?

echo "<h3 name=" . $some_array[2][$i] . ">" . $some_array[1][$i]. "</h3>";

Try this:

echo "<h3 name={$some_array[2][$i]}>{$some_array[1][$i]}</h3>";

It should be count($some_array[1]), because now you only count $some_array[x] and not how many keys $some_array[x][y] where y is.

Try

 echo '<h3 name="'.$some_array[2][$i].'">'.$some_array[1][$i].'</h3>';

Also consider the execution cost & potential error of using count within the loop. Instead consider

$cnt = count($some_array);
for($=0;$i<$count;$i++){

Check out the manual on Strings

Essentially, for expressions you need to use the "{}" or "Complex (curly) syntax" with double quotes.

$some_array[0]

Would work without the complex curly syntax, but you accessing another level deep of an array, hence it not working.
