Question

I need a str_replace or anything that act after first element like this:

"Hello-World-I-am-Pr-Pro"

and That's Result I want:

"Hello-World I am Pr Pro"

So you are looking for built-in functions to suit your custom functionality? — Anurag Srivastava

The PHP regex engine will do that for you using preg_replace:

function replaceViaRegex($needle, $to, $haystack)
{
    $regexStr = '/'.preg_quote($needle, '/').'/';
    $result = preg_replace($regexStr, $to, $haystack, 1);
    return $result;
}

$foo = "Hello-World-I-am-Pr-Pro";
$foo2 = replaceViaRegex('-', ' ', $foo); 

echo $foo2;

Alternately, you could do

$foo = "Hello-World-I-am-Pr-Pro";
$regex = '/-/';
$foo2 = preg_replace($regex, ' ', $foo, 1);

... but that is far less flexible. Or even

$foo2 = preg_replace('/-/', ' ', "Hello-World-I-am-Pr-Pro", 1);

... but I've had trouble making preg_replace work in the past w/out a variable so I just avoid making it that dense.

I made the function above extremely clear and simple so that you could follow the logic and modify as you choose. You are far better off working with the first version than the other two if you want good, maintainable code.

there is no shorter Answer?! Need Shorter! I think must be!

That is basically a 1 line fix... I'm not sure how much shorter you need. Once you add the function then replaceViaRegex('-', ' ', $foo); will do whatever you want from then on and you can vary as needed. No need to repeat code other than that single line. Does that make sense? This is an extremely common pattern in coding when you want a specific function for some result.
