Hi,
I have two lines here as follows:
1 -0.123701962557954E+03 0.460967618024691E+02
-0.12354765900E+03 0.46259109000E+02
What I am trying to do here is to only have
1 -0.123701962557954E+03 0.460967618024691E+02 be the output so I can do further processing with it, however, with the code I have in the following, I have both lines in the output. Here is the code:
$file = "test.txt";
$fp = fopen($file, "r");
$lines = file($file);
foreach($lines as $line_num = $line)
{
if (preg_match("/([^0-9]+\s+)(\-?\d+\.?\d+(\+?E?\d+)?){2}/", $line))
echo $line;
}
Could anyone please tell me that even when I specify that the line has to start with [^0-9]+\s with one occurrence, why I still get -0.12354765900E+03 0.46259109000E+02?
Thanks a lot for your help.
Alice

^[0-9] is the right way..

Re: [PHP] How can an elephant count for nothing?

While PHP has a lot of nice features, it also has some traps which I am forever falling
into. One which I find particularly hard to understand is how mixed mode comparisons work.
For instance
$string = 'elephant';
If($string == 0) returns true;
If($string != 0) returns false;
If($string === 0) returns false;
I know that in this case I should use 'If($string == '')', but I still manage to forget.
Can anyone explain clearly why comparing a string with zero gives this apparently
anomalous result?
it's called auto-casting (or auto-typecasting) and it's 'by design'
... welcome to the world of dynamic typing.
try this to see it working:
php -r '
var_dump((integer)"elephant");
var_dump((float)"elephant");
var_dump((bool)"elephant");
var_dump((array)"elephant");
var_dump((object)"elephant");
var_dump((bool)(integer)"elephant");
'
you can avoid auto-casting if needed, in a variety of ways:
php -r '
$foo = "elephant";
if (!empty($foo))
echo "$foo found!\n";
if (strlen($foo))
echo "$foo found!\n";
if (is_string($foo) strlen($foo))
echo "$foo found!\n";
if ($foo !== "")
echo "$foo found!\n";
if ($foo === "elephant")
echo "$foo found!\n";
'
those last 2 show how to use 'type-checked' equality
testing.
because intval("elephant") == 0;
intval will convert the string into integer , Strings
will most likely return 0 although this depends on the leftmost
characters of the string.

So I have a tokenmap.php that I include include in different configuration

So in my tokenmap.php I have declared an array as global.
SO $GLOBAL['tokenmap'] = array()
As a good programming practice what I did was:
require_once('tokenmap.php');
$tokenmap = array();
$tokenmap = $GLOBAL['tokenmap'];
print_r($tokenmap);
The above displays empty array
But when I do this , it works
require_once('tokenmap.php');
$tokenmap = $GLOBAL['tokenmap'];
print_r($tokenmap);
Its kind of wierd for me. I am trying to understand. Can some one shed some
light on it for me.
Thanks
