Replace content between two words

Question

I am trying to replace the content between two words using php. The content between the two words is different so I can't use tradition str_replace. I want to replace the content between two words for example:

I would like to replace **some string of text** between two words

change to:

I would like to replace between two words

You can see that I removed all the wording between "some" and "text". Again I cannot use regular str_replace because the text between the two words may differ. For example it may say:

I would like to replace **some words of text** between two words

change to:

I would like to replace between two words

`$txt = preg_quote('some string of text'); $new = preg_replace("/$txt/", 'new text', $old);` doesn't work? — Marc B, Sep 30 '12 at 19:32

The regex is simple: /some .*? text/

Just replace it with the empty string.

According to your question, only the inner part of your string changes. If that is the case it's rather trivial, because you already have the solution: You do not need to replace it, but you just need to not take it over:

$result = substr($string, 0, $startlen) . substr($string, -$endlen);

Probably this helps you to find some more "resolution angles" for such problems.
