Question

this is what I try to get:
My longest text to test When I search for e.g. My I should get My longest

I tried it with this function to get first the complete length of the input and then I search for the ‘ ‘ to cut it.

$length = strripos($text, $input) + strlen($input)+2;

$stringpos = strripos($text, ' ', $length);

$newstring = substr($text, 0, strpos($text, ' ', $length));

But this only works first time and then it cuts after the current input, means
My lon is My longest and not My longest text.

How I must change this to get the right result, always getting the next word. Maybe I need a break, but I cannot find the right solution.

UPDATE

Here is my workaround till I find a better solution. As I said working with array functions does not work, since part words should work. So I extended my previous idea a bit. Basic idea is to differ between first time and the next. I improved the code a bit.

function  get_title($input, $text) {
    $length       = strripos($text, $input) + strlen($input);   
$stringpos = stripos($text, ' ', $length);
// Find next ' '
$stringpos2 = stripos($text, ' ', $stringpos+1);

if (!$stringpos) {
    $newstring = $text;
} else if ($stringpos2) {
    $newstring = substr($text, 0, $stringpos2);
}  }    

Not pretty, but hey it seems to work ^^. Anyway maybe someone of you have a better solution.

You can try using explode

$string = explode(" ", "My longest text to test");
$key = array_search("My", $string);
echo $string[$key] , " " , $string[$key + 1] ;

You can take i to the next level using case insensitive with preg_match_all

$string = "My longest text to test in my school that is very close to mY village" ;
var_dump(__search("My",$string));

Output

array
  0 => string 'My longest' (length=10)
  1 => string 'my school' (length=9)
  2 => string 'mY village' (length=10)

Function used

 function __search($search,$string)
 {
    $result = array();
    preg_match_all('/' . preg_quote($search) . '\s+\w+/i', $string, $result);
    return $result[0]; 
 }
