PHP Foreach没有显示正确的输出？

Question

I'm having trouble with my foreach loop.

On my script:

$Tags = "PHP,HTML,CSS,Java";
$ExplodedVar = explode(",", $Tags);
print_r($ExplodedVar);
foreach ($ExplodedVar AS $NewStr)
{
    echo "<a href='#>$NewStr</a>,";
}

The print_r($ExplodedVar);

Is displaying the correct output of:

Array ( [0] => PHP [1] => HTML [2] => CSS [3] => Java )

foreach loop outposts only HTML & Java

You missed the close quote ' of href.

foreach ($ExplodedVar AS $NewStr)
{
  echo "<a href='#'>$NewStr</a>,";
}

And if the data is user input, then you need to sanitize the data.

foreach ($ExplodedVar AS $NewStr)
{
  echo "<a href='#'>". htmlspecialchars($NewStr)."</a>,";
}
