I'm using PHP to create some basic HTML. The tags are always the same, but the actual links/titles correspond to PHP variable开发者_开发百科s:
$string = '<p style="..."><a href="'.$html[$i].'"><strong><i>'.$title[$i].'</i></strong></a>
<br>';
echo $string;
fwrite($outfile, $string);
The resultant html, both as echoed (when I view the page source) and in the simple txt file I'm writing to, reads as follows:
<p style="..."><a href="http://www.example.com
"><strong><i>Example Title
</i></strong></a></p>
<br>
While this works, it's not exactly what I want. It looks like PHP is adding a line break every time I interrupt the string to insert a variable. Is there a way to prevent this behavior?
Whilst it won't affect your HTML page at all with the line breaks (unless you are using pre
or text-wrap: pre
), you should be able to call trim()
on those variables to remove newlines.
To find out if your variable has a newline at front or back, try this regex
var_dump(preg_match('/^\n|\n$/', $variable));
(I think you have to use single quotes so PHP doesn't turn your \n
into a literal newline in the string).
My guess is your variables are to blame. You might try cleaning them up with trim
: http://us2.php.net/trim.
The line breaks show up because of multi-byte encoding, I believe. Try:
$newstring = mb_substr($string_w_line_break,[start],[length],'UTF-8');
That worked for me when strange line breaks showed up after parsing html.
