strpos("abc","a") returns 0 because "a" is found at index 0.
strpos("abc","x") also returns 0 because "x" is not found.

It would be better if strpos returns -1 when search-string
not found.

Not true.  strpos("abc","x") returns an empty string ("") not 0 while
strpos("abc","a") returns 0.  You can distinguish between the two
cases with something like: if(strlen(strpos("abc",$char)) echo "Found";
Returning -1 would be inconsistent with the rest of PHP.
