How this change is written in the Foreach Loop

Output of the same, but the style is not the same,
First output
Topic 1
A second output
Topic 2 |(No Label and followed by a|）
And so on
I only wrote the first one, the second one will not write, I also know to use judgment, but do not know how to write

You didn't tell me what the rules of change were.

You didn't tell me what the rules of change were.

is to output one row at a separate line, such as
The first line, output itTopic 1
The second line, output it title 2|

And then the third line outputs the first time this styleTopic 1
Row four, then output the second row of Style topic 2|，
Line five again repeat the first style of the output, line sixth then output the second style, and so on, loop up. ...。 ......... Got it.

Can be easily referenced under the following:

$array = Array (1,2,3,4,5,6,7,8,9,10);        $num =1;        foreach ($array as $key = + $value) {            if ($num%2==0) {                echo ' title '. $value. ' |';            } else{                Echo ' title '. $value. '  ;            }            $num + +;        }
