Looping Through Multi-Dimensional Arrays Using Foreach

In PHP, can you loop through a multi-dimensional array using the “foreach” function, but only make it output key/value pairs that match a specific value?

foreach will only loop though the elements of the selected array

if you want to display all the dimentions of an array use the function

print_r($array);

if you only want to print out certain parts of an array, you could use this function



that will do the same as print_r(); however you can then limit what is printed by placing some conditions where i have the line

echo "$key: $value<br>";

so you could change that to

if($key == $name)
{
echo "$key: $value<br>";
}

so now it will only print the array element when key == name

An oldie but goodie. Helpful stuff, thanks.

Just a couple typos tho. Missing closing parens and semi-colon. It should read:
...
if(is_array($value))
{

// the value of the current array is also a array, so call this function again to process that array

PrintArray($value);

}
...
