Question

A piece of code would explain my problem

$string = '53 69 cm; 988 2460 g; wing 106 116 cm';
$patterns = array();
$patterns[0] = '/[0-9]+\s[0-9]+/';
$replacements = array();
$replacements[0] = '$0';
echo preg_replace($patterns, $replacements, $string,1);

I need to put a – between numbers, like:

$string = '53-69 cm; 988-2460 g; wing 106-116 cm';

How can I put the – on the replacement?

Thanks

Hope this gives you some help:

$string = '53 69 cm; 988 2460 g; wing 106 116 cm';
$pattern = '/(\d+)\s(\d+)/';
$replacement = '$1-$2';
echo preg_replace($pattern, $replacement, $string);

Output:

53-69 cm; 988-2460 g; wing 106-116 cm
