Print only first sentence

[dc_jt]

Hi

 

I have the following:

 

<?=strip_tags(substr($oTeam->description,0,140))?><?=(strlen($oTeam->description) > 140) ? '...' : ''?>

 

However, this displays the first 140 characters. I want to be able to display only the first sentence, basically everything upto the first full stop or question mark etc.

 

Any idea how?

 

Thanks

use an offset of 140 on a few strpos() calls that are looking for fullstops and question marks. After that just check which one is shorter and use that value with substr().

Got this function:

 

$aPara = 'this is my para? this is the second sent';

   

$aSent = split('[?!.]',$aPara);

   

print $aSent[0];

 

 

But it takes off the [?!.] at the end so its not perfect but might have to do

I dont your code for two reasons the first is it returns an array and the second is it will be slower on larger documents. You are only selecting the first sentence in your example but if you are selecting from a document the array will have all the other sentences in them too.

 

This is the implementation of what i described in my previous post.

<?php
function firstSentence($text)
{
if ($f = strpos($text, '.'))
	$a[] = $f;

if ($q = strpos($text, '?'))
	$a[] = $q;

if ($x = strpos($text, '!'))
	$a[] = $x;

        if ($a)
        	return substr($text, 0, min($a) + 1);	
}

echo firstSentence('some text. here?');

//output 'some text.'
?>
