[SOLVED] Adding text

[redfox180]

Hi,

 

if I have some text like this:

 

PD32TR/PD54YT/PD43QW/512RE/51QW/PD43WQ/...

 

I would like to ad PD to all those ones who haven't. Any suggestion??? Keep in mind that the dispositions can change.

Thanks

James

Try something like this:

 

$parts = explode('/', $string);
foreach($parts as $key => $part)
{
if(substr($part), 0, 2 != 'PD') $parts[$key] = 'PD' . $parts[$key];
}
$string = join('/', $parts);

It doesn't seem to work...

Well, I just misplaced a ). Another time though, please state how "it isn't working".

 

<?php
$string = 'PD32TR/PD54YT/PD43QW/512RE/51QW/PD43WQ';

$parts = explode('/', $string);
foreach($parts as $key => $part)
{
if(substr($part, 0, 2) != 'PD') $parts[$key] = 'PD' . $parts[$key];
}
$string = join('/', $parts);

echo $string; // output: PD32TR/PD54YT/PD43QW/PD512RE/PD51QW/PD43WQ
?>

Sorry Daniel, I realized it only ofter I posted it...

Thanks!

$string=preg_replace('/\/(/d/d..)\//','/PD$1/',$string);

 

[Daniel0]

$string=preg_replace('/\/(/d/d..)\//','/PD$1/',$string);

 

That will result in an E_WARNING. I see what you're trying to do though, but it won't work if the item is the first or last.

TMTOWTDI:

<pre>
<?php
$data = 'PD32TR/PD54YT/PD43QW/512RE/51QW/PD43WQ';
echo preg_replace('%(?<=\A|/)(?!PD)%', 'PD', $data);
?>
</pre>

TMTOWTDI?

Hrmmm...

 

 

I hadn't ever seen that either....

 

First Google result:

 

TMTOWTDI: /tim�toh'�dee/, abbrev.

There's More Than One Way To Do It. This abbreviation of the official motto of Perl is frequently used on newsgroups and mailing lists related to that language.

$string=preg_replace('/\/(/d/d..)\//','/PD$1/',$string);

oh, yup you're right.
