Question

$string = "Some words here. More words, followed by 1.5 and 2.3 here.Here is no space after the dot."

I need to add the white space after the dot between sentences (if there is no one), but don’t change dots in floats.

$result = "Some words here. More words, followed by 1.5 and 2.3 here. Here is no space after the dot."

Was “here.Here”
Became “here. Here”

Tried a lot, but can’t find the solution.

Answer 1

This should do it…

preg_replace('/([a-z]+)\.([^\s])/i', '$1. $2', $string);
