You could use preg_match()
. I'm not so good with regular expressions but I hope this'll solve your problem.
$str = "i want to buy a new car";
preg_match("/\S*\s\S*\s\S*/", $str, $result);
echo $result[0]; //prints: I want to
hello v1shwa thanks for reply
yes it's work
but how about i change show five or seven words ?
i dont understand this code "/\S\s\S\s\S*/"
please help
You can use substr
$string = 'I want to buy a new car';
echo substr($string, 0, 9);
The first param is the string, the second param is where to start and the third param is the length.
This would be a more dynamic approache. You can set all params to variables.
<?php
$sentence = 'I want to buy a new car';
function num_words_from_sentence($num, $sentence)
{
$pattern = str_repeat("\S*\s*",$num);
preg_match("/$pattern/", $sentence, $result);
return trim($result[0]);
}
for($num=1;$num<8;$num++)
echo $num . ': ' . num_words_from_sentence($num, $sentence) . '<br />';
Result:
1: I
2: I want
3: I want to
4: I want to buy
5: I want to buy a
6: I want to buy a new
7: I want to buy a new car
