Php内爆空数组[重复]

• How can I implode an array while skipping empty array items? 8 answers

I have a simple array with no values assigned:

Array
(
    [field1] => 
    [field2] => 
)

then doing something like:

$result = array();
foreach ($array as $val) {
   array_push($result, $val);
}

$data = implode("::", $result);

I end up with:

::

So how can I prevent implode generating separator if array values are empty? If I have at least one value assigned:

Array
(
    [field1] => "hello"
    [field2] => 
)

Then implode does it's job fine.

You can use array_filter() , for example in your case:

implode( ':', array_filter( $result ) );

That will filter your array before imploding it.
