strpos & echo not working?

[jacko_162]

im trying to use strpos to find the location after 15 characters, then i need to echo the "$data["content"] limiting it to the first white space after 15 chars, and adding the trailing dots.

 

the echo only shows "..." not the content?

 

where am i going wrong???

 

 

// first find the first space after 15 characters, this should be the end of a word
$offset = strpos($data["content"], "", 15) ;
//then put into variable
$shorter_list = substr($data["content"],0,$offset);
//then echo the variable with trailing dots
  echo $shorter_list."...";

Got to include some whitespace in there:

$offset = strpos($data["content"], ' ', 15) ;

His should work.

 

More complete

 

$str = 'This is a long string we want broken after 15 characters';

echo substr($str,0,strpos($str,' ',15)).'...';

even as 1 string its still only echoing the "..." hmmmm is this an old php function?

What? Copy n Paste my example! It works

If i use the below i just get "..."

 

<?php  

$results = mysql_query("SELECT * FROM $table3 ORDER BY id ASC LIMIT $page, $limit");
while ($data = mysql_fetch_array($results))
  
  $str = $data["content"];
  echo substr($str,0,strpos($str,' ',15)).'...';
}
?>

 

but if i just echo $data["content"]; then i get the full content field??!

Hey man, try using the function I use for this..

 

<?php
$string = 'blah blah'
echo short_str($string, 'maxnumberofcharacters');

function short_str($str, $in) {
$strlen = strlen($str);
if($strlen > $in):
	$cutamount = $in-$strlen-3;
	$out = substr($str, 0, $cutamount);
	return $out.'...';
elseif($strlen <= $in):
	return $str;
endif;
}
?>

ok i decide to use;

 

echo substr($data["content"], 0, 25).'..';

 

it works fine for limiting the content, problem now is the content now may contain html stuff... how can i strip all html out of it before echo??

 

if you understand what i mean, its a simple news page with a wysywig input that stores it in db, i then need to echo the first 25 characters of it for example.

Try:

<?php  

$results = mysql_query("SELECT * FROM $table3 ORDER BY id ASC LIMIT $page, $limit");
while ($data = mysql_fetch_array($results))
  
  $str = $data["content"];
  echo (strlen($str) > 15) ? substr($str,0,strpos($str,' ',15)).'...' : $str;
}
?>

Try:

<?php  

$results = mysql_query("SELECT * FROM $table3 ORDER BY id ASC LIMIT $page, $limit");
while ($data = mysql_fetch_array($results))
  
  $str = $data["content"];
  echo (strlen($str) > 15) ? substr($str,0,strpos($str,' ',15)).'...' : $str;
}
?>

 

Cheers buddy, you're code with a little addition = happy man

 

<?php    
  $str = $data["content"];
  $str2 = strip_tags($str);
  echo (strlen($str2) > 35) ? substr($str2,0,strpos($str2,' ',35)).'........' : $str2;
?>
