PHP to echo a line in html source...

Here an unusual one...

Say i am writing a few lines of code in php script as so...

<?php
echo '<table>';
echo '<tr>';
echo '<td> blah blah </td>';
echo '</tr>';
echo '</table>';
?>

On my html source the code looks like this...

<table><tr><td>blah blah</td></tr></table>

Is there anyway I can get each html tag on a seperate line in the html
source so it is nice and neat (easy readable)?

Thanks

echo "<table>\n";

How about:

<?php
$tmp = array();
$tmp[] = '<table>';
$tmp[] = "\t".'<tr>';
$tmp[] = "\t\t".'<td> blah blah </td>';
$tmp[] = "\t".'<tr>';
$tmp[] = '</table>';
echo implode("\n",$tmp)."\n";
?>

I use similar constructs all the time. It make for nice readable code.

Let me also point out that Andy used double-quotes. Doing this:

echo '<table>\n';

will not produce the same output.

I recommend that you not echo, line by line, large blocks of HTML like you
have done. Makes it quite hard to read (and debug or alter or update).

Many ways.
First one (using double quotes and escape sequence \n):

<?php
echo "<table>\n";
echo "<tr>\n";
echo "<td> blah blah </td>\n";
echo "</tr>\n";
echo "</table>\n";
?>

or:

<?php
echo "<table>\n<tr>\n<td> blah blah </td>\n</tr>\n</table>\n";
?>

or:

<?php
echo '<table>'."\n";
echo '<tr>'."\n";
echo '<td> blah blah </td>'."\n";
echo '</tr>'."\n";
echo '</table>'."\n";
?>

or escaping to HTML:

<?php
// some PHP code
?>
<table>
<tr>
<td> blah blah </td>
</tr>
</table>
<?php
// other PHP code
?>

or using multiline strings (and double quotes):

<?php
echo "<table>
<tr>
<td> blah blah </td>
</tr>
</table>
";
?>

or (probably) many more.

That one thats worked for me is as follows... multiline string, with single
quotes. I needed to embed php variables into the string also... as
follows...
echo '<table border="0" cellspacing="0" cellpadding="0">
<tr>
<td><img src="gfx/interface/win_'.$wincol.'_tl.gif" width="10" height="10"
border="0"></td>
<td><img src="gfx/interface/win_'.$wincol.'_t.gif" width="'.$winwid.'"
height="10" border="0"></td>
<td><img src="gfx/interface/win_'.$wincol.'_tr.gif" width="10" height="10"
border="0"></td>
</tr>
<tr>
<td><img src="gfx/interface/win_'.$wincol.'_l.gif" width="10"
height="'.$winhgt.'" border="0"></td>
<td width="'.$winwid.'" height="'.$winhgt.'" bgcolor="#393939">';

My favorite for large blocks of HTML hasn't been mentioned yet. It is
the "here document" structure for defining a string:

<?php
$something = "blah blah"; # just to show off variable interpolation

echo <<<EOHEREDOC
<table>
<tr>
<td> $something </td>
</tr>
</table>
EOHEREDOC;

?>

Check out 'PHP "Here document" tutorial' with Google. Unfortunately
this form of defining a string is not covered very well in the PHP
manual.

The here document preserves whitespace and newlines, and interpolates
variables in the same way doublequote strings do.

Well, you CAN try to make it nice by yourself, but there's also the
possibility of letting software do that job. With "tidy" one can
prettyprint HTML code and there are possibilities do automagically use
it when sending HTML to the browser. There are extension to PHP that
allow for this. You should read a bit about using the output buffers or
the tidy extension.

As an appetizer, just have a look at this comment:
