在php字符串中查找相同的两个字符之间的文本

So I know how to extract text from a php string when it is cleanly separated by two different characters (ie. [abc])...

However, I am now facing a problematic situation where I need to extract text that is located between two instances of the same character ('/'). What makes it even trickier is that this can happen multiple times within the same string.

An example should help make this clearer:

"This is /a/ silly ex/amp/le of what I /me/an."

In this case, I would want to grab 'a', 'amp' and 'me'.

These examples show the variety of cases I might run into (different lengths and cases where I'm not grabbing a whole word but letters within a word).

What I've tried:

('/(\/.+?)+(\/)/i')

But this, as expected, captures everything between the first and last slashes. The ideal would be a way to match until the NEXT occurrence of a slash, rather than the last one...

I've been googling this for quite some time, but am only coming up with cases with two different delimiters.

    You can use preg_match_all to get multiple matches.

    $string = 'This is /a/ silly ex/ampl/e of what/ I me/an';
    $regex = '/\/.+?\//';
    preg_match_all($regex, $string, $matches);
    
    print_r($matches);
    
    
    Array
    (
        [0] => Array
        (
            [0] => /a/
            [1] => /ampl/
            [2] => / I me/
        )
    )
