Hi guys...
Yes I know that this is a small function and yes I know it can be
copy-paste with every new project you do but from the first day I've
been using PHP until today this function follows me everywhere and I now
that everyone is using it one way or the other for debugging......
the problem is when you want to debug a piece of code separately or use
it in one script then you have to find the function...copy paste to that
script or write it again just for that script...and so on...it would be
great if it could be in the php core....
I have a very basic knowledge of C so implementing this function would
be a nightmare for me but for someone who knows C and the inner
"mysteries" of the Zend Engine :) this is a piece of cake....
Ok...here it is...don't laugh :)
/**
- Prints the variable in HTML format...
- @param mixed $var
- @param bool $return return or print the var
- @return string
*/
function print_pre($var, $return = false) {
$retval = »<pre>«.print_r($var, true).</pre>«;
if($return) return $retval;
print($retval);
}
ok....let the shooting begin :)
Hmm, it's no GOTO, but oddly enough we have virtually exactly the same
function and use it everywhere too. The only differences are we call ours
pre_r() and we add the following check against php_sapi_name() so that the
function behaves sanely when called from the cli:
function pre_r($mixed, $return) {
if ( php_sapi_name() == "cli" ) {
if ( $return )
return print_r($mixed, true);
print_r($mixed);
} else {
if ( $return )
return "<pre>" . print_r($mixed, true) . "</pre>";
echo "<pre>";
print_r($mixed);
echo "</pre>";
}
}
While I don't know if it needs to be in the core, if it were I'd certainly
use it.

Click "report a bug" and choose "Feature/Change Request" as the "Type of

But don't bother - this was requested before and denied.

If you really-really want it on your own build, just apply this short patch.

the xdebug extension has very nice html-ized var_dump(). Use that on
your devel machine and you'll never need your print_pre again.
Otherwise I find it easier to simply do this:
<?php
echo '<pre>';
var_dump($blah);
echo '</pre>';
?>
than to write a function and make sure it is always there.
Alternately, view source from your browser works great for grabbing
var_dump()/print_r() output.
