Get first image in string (Function issue)

[Mutley]

There is probably a better way of doing this but the problem I'm having is it puts the images at the top of the page (before EVERYTHING else).

 

The PHP is in a loop, so it looks at 5 different strings then echos the image. here's my code ($r['content'] being the string it looks for the image).

 

Funtion:

<php>

ob_start();

function bm_extract_string($start, $end, $original) {

$original = stristr($original, $start);

$trimmed = stristr($original, $end);

return substr($original, strlen($start), -strlen($trimmed));

}

</php>

 

Echo bit (this is in a loop):

<php>

$content = $r['content'];

$pic_string = bm_extract_string("src='","' ",$content);

echo '<img src="'.$pic_string.'" />';

</php>

 

 

Any ideas? I don't think the page code will make much sense as it's IPB3 but here it is:

 

<php>
ob_start();
function bm_extract_string($start, $end, $original) {
$original = stristr($original, $start);
$trimmed = stristr($original, $end);
return substr($original, strlen($start), -strlen($trimmed));
}
</php>

<script type='text/javascript'>
                Event.observe( window, 'load', function(){
                        // Resize images
                        $$('.hentry').each( function(elem){
                                ipb.global.findImgs( $( elem ) );
                        });
                });
</script>



<ul class='hfeed'>
	<if test="is_array( $records ) && count( $records )">
	{parse striping="feed_striping"}



<foreach loop="$records as $r">
	<li style="padding:10px" class='hentry {parse striping="feed_striping"}'>

<php>
$content = $r['content'];
$pic_string = bm_extract_string("src='","' ",$content);
echo '<img src="'.$pic_string.'" />';
</php>

<a href='{$r['url']}' rel='bookmark' title='{$r['title']}'><h2 style="font-size:24px; font-weight:bold; margin-bottom:0px; border-bottom:1px #284B72 solid; width:100%">{$r['title']}</h2></a>

<div style="float:left; padding-top:2px">

</span>
<br /><br />

<div class='desctext' style="padding-left:25px">{$r['content']}
</div>
	</li>
<br />
</foreach>

	</if>
</ul>
<br /><br />

 

Thanks in advance.

try

<?php
function bm_extract_string($start, $end, $original) {
$original1 = stristr($original, $start);
$trimmed = stristr($original, $end);
return substr($original, $origil1+strlen($start), $trimmed-$original1-strlen($start));
}
$content = $r['content'];
$pic_string = bm_extract_string("src='","' ",$content);
echo '<img src="'.$pic_string.'" />';
?>

try

<?php
function bm_extract_string($start, $end, $original) {
$original1 = stristr($original, $start);
$trimmed = stristr($original, $end);
return substr($original, $origil1+strlen($start), $trimmed-$original1-strlen($start));
}
$content = $r['content'];
$pic_string = bm_extract_string("src='","' ",$content);
echo '<img src="'.$pic_string.'" />';
?>

 

No, that didn't work either.

ups

<?php
function bm_extract_string($start, $end, $original) {
$original1 = stripos($original, $start);
$trimmed = stripos($original, $end);
return substr($original, $original1+strlen($start), $trimmed-$original1-strlen($start));
}
$content = $r['content'];
$pic_string = bm_extract_string("src='","' ",$content);
echo '<img src="'.$pic_string.'" />';
?>

Is that just with the spelling corrections? I spotted those and fixed them before.  But sadly it didn't work either.

 

I don't know why, it just seems to be dumping PHP at the very top of the page. Even if I don't use a function to do the job.

i try this code

<?php
function bm_extract_string($start, $end, $original) {
$original1 = stripos($original, $start);
$trimmed = stripos($original, $end);
return substr($original, $original1+strlen($start), $trimmed-$original1-strlen($start));
}
//$content = $r['content'];
$content = "bla bla bla src='picture.bmp' bla bla";
$pic_string = bm_extract_string("src='","' ",$content);
echo '<img src="'.$pic_string.'" />';
?> 

and it outputs

<img src="picture.bmp" />
