word count script help

[aron]

hi all i have this script and it works, i want to change it slightly so that it counts how many words and if its more that 50 then it writes "...more" if its not then dont write anything.

<?
while ($line = mysql_fetch_array($sql_result, MYSQL_ASSOC)) {

$content = $line["news"];
$content=substr($content,0,50);
$content=substr($content,0,strrpos($content," "));
?>
<span class="bodybluebold"><? print $line["date"]; ?></span><br>
<span class="body"><? echo "$content"; ?>"write ..more here"<br>
<br>
<?
}
/ Free resultset /
mysql_free_result($sql_result);
?>

cheers aron.

<? echo "$content"; if str_word_count($content , =>50)
{
echo "...more";
}?>

[LordShryku]

echo (str_word_count($content) => 50) ? $content.'...more' : $content;

You never closed the function before the check.

Parse error: parse error, unexpected T_DOUBLE_ARROW in C:\Inetpub\vhosts\conetix.com.au\httpdocs\index.php on line 552

Yeah, that should be >=

[aron]

no erros but no ..more eather

<? echo (str_word_count($content) >= 50) ? $content."...more" : $content; ?>

i want it to write ...more if there are more than 50 words

cheers aron.

Worked fine for me....
Try echoing the str_word_count to see how many words it's says there are.

[aron]

ok it works and i know whats wrong.

i think this is counting characters insztead of words

$content = $line["news"];
$content=substr($content,0,50);
$content=substr($content,0,strrpos($content," "));

how do i change it..

cheers aron.

[LordShryku]

Remove the second two lines. It's not counting, it's cutting it down to 50 characters.

[aron]

yes but i stil only want to show 50 words..

[LordShryku]

Read the manual page on str_word_count. It can pull the 50 words out for you...
As it stands you were cutting it after 50 characters, not words.

   $offset=4;
$content = "tyrtet dhdgdf dhgdiufu fdifufy dhd";
//for words
$wordarray  = str_word_count($content, 2);
$content=(count($wordarray)>$offset)?implode(' ',array_slice($wordarray,0,$offset)).'...more':$content;
echo $content; 
// output : tyrtet dhdgdf dhgdiufu fdifufy...more

//for chars
$content=(strlen($content)>$offset)?substr($content,0,strpos($content,' ',$offset)).'....more':$content; 
echo '<br>'.$content;
//output : tyrtet....more
