除非最终结果，否则在foreach期间回显文本

Question

I currently have my code to output data from a database but I am unsure of how to append text during a foreach where the result is not the final entry.

//Print each result 
foreach($new_array as $array){

//print out a result with formatting  
Echo $Content1 = <<<CONTENT1
{"
CONTENT1;

Echo $array['f1'];

Echo $Content2 = <<<CONTENT2
"}{"
CONTENT2;

Echo $array['f2']; 

Echo ".";

Echo $array['f3'];

Echo $Content3 = <<<CONTENT3
"}
CONTENT3;

Echo ", " //If not final entry

};

?> 

So in short transforming the output from;

{"Entry"}{"Name.ID"}{"Entry"}{"Name.ID"}

to;

{"Entry"}{"Name.ID"}, {"Entry"}{"Name.ID"}

Try this

$endvar=end($new_array);

it will store the last value in the array and then you can check it using if condition

foreach($new_array as $array){
if($array==$endvar)
{
// do whatever you want to do here
}
else
{
// else code
}
}
