limit echo in php to certain word in string

esteeven · 11-30-2009, 10:18 AM

Hello

I am a bit stuck with a php problem. I have a string of text that can be of a variable length eg

" Large and luxurious 5th floor 2 bed furnished apartment in a fantastic historic building close to the City Centre and Waterfront.

More details and 8 photos
Save property
Contact agent "

The text in the first 2 lines can be variable in length. The "More details... etc" is standard text. I want to display my string up to, but not including, the word "More."

I am looking (I think) for something like :

echo $mystring (up to the word "More") << this is the bit I can't work out.

Thanks

explode on newline, then get element 1 of the exploded array

I should have been clearer. I am taking the text string from another page using :

$content = file_get_contents('http://www.......);

I have then (somehow http://ubuntuforums.org/images/smilies/icon_smile.gif ) managed to get the text string I want using :

$start_pointer = strpos($content, '<ol id="summaries"');
$end_pointer = strpos($content, '</ol>', $start_pointer);
$properties_content_length = $end_pointer - $start_pointer;
$properties = substr($content, $start_pointer, $properties_content_length);

$property_list = explode('<li class="regular',$properties);

$property_nbr = count($property_list);
echo '<li class="';

echo strip_tags($property_list[ rand(1, $property_nbr)-1], '<p><img><li><span><div><h2>');

This works fine, except that I want to limit the "echo $property_list" to a certain word eg the "More" in my string below.

" Large and luxurious 5th floor 2 bed furnished apartment in a fantastic historic building close to the City Centre and Waterfront.

More details and 8 photos

How and where do I explode again?

Thanks

you will need to use a combination of substr() and strripos()

something like this

PHP Code:



$string = some stuff there and then your thing... More Details, etc; 
 
 
//find the more details position 
 
$position = strripos($string,"More Details");  
 
//then get the string up to the location of the above position 
 
$remaining = substr($string,0,$position);

that should get it close, you may need to tweak it a little to get the Char position just right.

you can also condense it, but kept it open to show you what was happening exactly.

The solution (for me) was :

$home_properties=strip_tags($property_list[ rand(1, $property_nbr)-1], '<p><img><li><span><div><h2>');
$lines=explode("More details",$home_properties);
echo $lines[0];
