Witam,
Mam taki oto kod:

Jak zrobić, żeby generując $photo->filename skrypt kasował mi cztery ostatnie znaki.
Teraz pokazuje mi się cała nazwa pliku, razem z rozszerzeniem. Kasując 4 ostatnie znaki zniknie akurat rozszerzenie.
Proszę o pomoc.

[PHP] pobierz, plaintext 
<img class="sigFreeImg" src="<?php echo $transparent; ?>" alt="<?php echo JText::_('JW_PLG_SIG_CLICK_TO_ENLARGE_IMAGE').' '.[color="#FF0000"]$photo->filename[/color]; ?>" title="<?php echo JText::_('JW_PLG_SIG_CLICK_TO_ENLARGE_IMAGE').' '.$photo->filename; ?>" style="width:<?php echo $photo->width; ?>px;height:<?php echo $photo->height; ?>px;background-image:url(<?php echo $photo->thumbImageFilePath; ?>);" />
[PHP] pobierz, plaintext 

Całość pliku:

[PHP] pobierz, plaintext 
<?php
 
// no direct access
defined('_JEXEC') or die('Restricted access');
 
 
?>
 
<ul id="sigFreeId<?php echo $gal_id; ?>" class="sigFreeContainer sigFreeClassic<?php echo $extraWrapperClass; ?>">
	<?php foreach($gallery as $count=>$photo): ?>
	<li class="sigFreeThumb">
		<a href="<?php echo $photo->sourceImageFilePath; ?>" class="sigFreeLink<?php echo $extraClass; ?>" style="width:<?php echo $photo->width; ?>px;height:<?php echo $photo->height; ?>px;" rel="<?php echo $relName; ?>[gallery<?php echo $gal_id; ?>]" title="<?php echo JText::_('JW_PLG_SIG_YOU_ARE_VIEWING').'

		</a>
	</li>
	<?php endforeach; ?>
	<li class="sigFreeClear">&nbsp;</li>
</ul>
 
<?php if($itemPrintURL): ?>
<div class="sigFreePrintMessage">

A w jaki sposób to umieścić w moim kodzie:

Oryginał:
<img class="sigFreeImg" src="<?php echo $transparent; ?>" alt="<?php echo JText::_('JW_PLG_SIG_CLICK_TO_ENLARGE_IMAGE').' '.$photo->filename[/color]; ?>" title="<?php echo JText::_('JW_PLG_SIG_CLICK_TO_ENLARGE_IMAGE').' '.$photo->filename; ?>" style="width:<?php echo $photo->width; ?>px;height:<?php echo $photo->height; ?>px;background-image:url(<?php echo $photo->thumbImageFilePath; ?>);" />

Ani nie działa tak:
<img class="sigFreeImg" src="<?php echo $transparent; ?>" alt="<?php echo JText::_('JW_PLG_SIG_CLICK_TO_ENLARGE_IMAGE').' '.$photo->filename[/color]; ?>" title="<?php echo JText::_('JW_PLG_SIG_CLICK_TO_ENLARGE_IMAGE').' ' ?> <?php echo substr($photo->filename, 0, strlen($photo->filename)-4); ?>" style="width:<?php echo $photo->width; ?>px;height:<?php echo $photo->height; ?>px;background-image:url(<?php echo $photo->thumbImageFilePath; ?>);" />

Ani tak:
<img class="sigFreeImg" src="<?php echo $transparent; ?>" alt="<?php echo JText::_('JW_PLG_SIG_CLICK_TO_ENLARGE_IMAGE').' '.$photo->filename[/color]; ?>" title="<?php echo JText::_('JW_PLG_SIG_CLICK_TO_ENLARGE_IMAGE').' ' ?> <?php echo substr($filename, 0, strlen($filename)-4); ?>" style="width:<?php echo $photo->width; ?>px;height:<?php echo $photo->height; ?>px;background-image:url(<?php echo $photo->thumbImageFilePath; ?>);" />

Co robię źle?

po prostu zamień to co masz na
'.$photo->filename; ?>"
'.substr($photo->filename, 0, strlen($photo->filename)-4); ?>"

Dziękuję.
