Question

I use a spanish dictionary api that returns definitions with small issues. This specific problem happens when the definition has more than 1 sentence. Sometimes the sentences are not properly separated by a space character, so I receive something like this:

This is a sentence.Some other sentence.Sometimes there are no spaces between dots. See?

Im looking for a regex that would replace “.” for “. ” when the dot is immediately followed by a char different than the space character. The preg_replace() should return:

This is a sentence. Some other sentence. Sometimes there are no spaces between dots. See?

So far I have this:

echo preg_replace('/(?<=[a-zA-Z])[.]/','. ',$string);

The problem is that it also adds a space when there is already a space after the dot. Any ideas? Thanks!

Try this regular expression:

echo preg_replace('/(?<!\.)\.(?!(\s|$|\,|\w\.))/', '. ', $string);
