How to get the first paragraph bold in the php?

Question

I am entering text in the database in two paragraphs

first paragraph
second paragraph

I am storing them in my database and when I am displaying them on the frontend using nl2br it is getting displayed perfectly.

I want the my first paragraph to be bold and the second paragraph should be normal.

I tried using strpos to find the location of the <br> tag after nl2br to chop off the first paragraph but I am not succeeding.

the failed code is

echo strpos(nl2br($row['article']), "<br>");

but i am not getting the position of the <br> tag

I got the correct answer from eddie, he deleted it but i am updating the answer here

$str='first paragraph
      second paragraph';
foreach(explode("\n",) as $key => $val) { 
if($key == 0){
echo'<b>'; 
}     
echo $val;
echo'<br>';
if($key == 0){ 
echo '</b>';
}
}

So? You can still use CSS selectors to target the first paragraph only. — j08691, Jun 18 '14 at 02:38
Do you want the bold tags to also be inserted into DB? If not and as already stated, you can use CSS selectors to target the first paragraph only. If it's to go into DB, have you tried Eddie's answer below? — Funk Forty Niner, Jun 18 '14 at 02:40
unfortunately he deleted it, but i will update that in my question — Rajeev, Jun 18 '14 at 02:47
@UglyEddie You should undelete your answer. OP says it worked perfectly. — Funk Forty Niner, Jun 18 '14 at 02:48

Don’t use nl2br for the type of results you are looking for. Just split the string into an array using a regex rule with preg_split and then act on the first item in the array. Here is test code:

// Set the test data.
$test_data = <<<EOT
first paragraph
second paragraph
EOT;

// Split the test data into an array of lines.
$line_array = preg_split('/(\r?\n){1,2}/', $test_data);

// Roll through the line array & act on the first line.
$final_text = '';
foreach ($line_array as $line_key => $line_value) {
  if ($line_key == 0) {
    $line_value = "<b>" . $line_value . "</b>";
  }
  $final_text .= $line_value . "<br />\n";
}

// Dump the line array for debugging.
echo '<pre>';
print_r($line_array);
echo '</pre>';

// Echo the final text.
echo '<pre>';
echo htmlentities($final_text);
echo '</pre>';

die();

The output from the dump of the line array would be this:

Array
(
    [0] => first paragraph
    [1] => second paragraph
)

And the test output using htmlentities to show what was done HTML-wise:

<b>first paragraph</b><br />
second paragraph<br />

Try:

$first_line = explode(PHP_EOL, $str)[0];
$new_str = str_replace($first_line,'<b>'.$first_line.'</b>',nl2br($str));
