regex - PHP - Extract characters before and after first space

Solution:

What have you tried?

suggestion: explode() your string on the space character, get the first and last values in the array by index, then use substr() to fetch the characters you require.

Solution:

This should work correctly.

   $string = 'Bobby Ryan';

   $words = explode(" ", $string);
   $output = substr($words[0], 0, 2) . substr($words[1], 0, 3);

   echo $output;
Copy code

Solution:

Fromexplode()'s manual entry: (http://www.php.net/explode) -array explode ( string $delimiter , string $string [, int $limit ] ).

the optional$limit parameter indicates into how many pieces the string should be exploded to, and considering what you want to achieve, along withsubstr()(http://www.php.net/substr):

list($beforeSpace, $afterSpace) = explode(" ", $string, 2);
$output = substr($beforeSpace, 0, 2) . substr($afterSpace, 0, 3);
Copy code

will break the string into two strings right at the first space character, and then form the output from the first two characters of whatever was before the space, and the first three characters of whatever was after the space.

Solution:

$string = "Bobby Ryan";
$var=explode(" ",$string);
// Totally didnt debug this part, may have to change 2 and 3 to -1 to 1 and 2
$output = substr($var[0],0,2) +  substr($var[1],0,3);
Copy code

Solution:

If you want to use regex only:

$string = "Bobby Ryan";
$output = preg_replace("/(\w{2})\w* (\w{3})\w*/", "$1$2", $string);
Copy code

Solution:

You must first split the string into parts. Look at explode or some kind of String tokinizer. You must then use a substring function to get parts of the strings.

$string = "Bobby Ryan";
$output = getPartsOfString($string, 2, 3);
echo $output;

function getPartsOfString($string, $firstNumOfChars, $secondNumOfChars) {
{
    $part = explode(" ", $string);

    // Get substrings from parts
    return substr($part[0], 0, $firstNumOfChars).substr($part[1], 0, $secondNumOfChars);
}
Copy code

The function could have several more parameter. The start of first and second string. (The 0s in substring function) and a spesified delimiter. (Change to explode($delimiter, $string);

Hope this helps.
