Hi folks,
A strange one - unless I am having a brainstorm...
I am reading in tab delimited files created in Excel on Windows and
uploaded to Linux.
Cell A1 contains a numeric id - I extract this into a variable, $id,
by exploding on \n and \t.
But for some files, the values of $id do not behave as expected. Say
the value should be "23".
If I echo, it prints as "23". But comparisons fail to match:
if( $id == 23 ) ...
It also fails if I try to find the value as a key in an
array:
if( isset( $my_array[$id] ) ) ...
On the other hand, values from some of the files work as expected.
One clue: if I try and cast the values that are failing to int, the
cast produces the value 0 (zero). On the other hand, the values that
are working as expected cast from, say, the string 22 to the int 22 as
expected.
Never seen anything like this before - can anyone give me a pointer??
