"InStr" or "Mid" Functions?

[Anon]

Is there a PHP function that does the same thing as the Visual Basic "InStr" function?

The "InStr" function allows you to search a string for a specific set of characters. If the set of characters exists in the string, the "InStr" function returns the starting position of the set of characters.

Is there a PHP function that does the same thing as the Visual Basic "mid" function?

The "mid" function allows you to assign a portion of a string to another variable. You can specify the start position and the number of characters to return.

Thanks.

InStr() = strstr()
Mid() = substr()

I think a better question would be "where can I find the 'strings' section of the PHP manual?
