Question

From this string:

$input = 'Some terms with spaces between'; 

how can I produce this array?

$output = ['Some', 'terms', 'with', 'spaces', 'between']; 

Answer 1

You could use explode, split or preg_split.

explode uses a fixed string:

$parts = explode(' ', $string); 

while split and preg_split use a regular expression:

$parts = split(' +', $string); $parts = preg_split('/ +/', $string); 

An example where the regular expression based splitting is useful:

$string = 'foo   bar';  // multiple spaces var_dump(explode(' ', $string)); var_dump(split(' +', $string)); var_dump(preg_split('/ +/', $string));
