Re: [PHP] help with \n\r in strings

If you just want to test for \n\r -

if ( substr ( -2, $my_string ) == "\n\r" ) { // substr with the negative value of 2 will give you the last two characters of your string
// do some stuff
}

I think it would be a good idea to explain a little bit more what you are trying to accomplish. Are you preparing the string for a database insert? Do you want to sanitise the string?

Stripping off those kind of characters can also be done with trim (or ltrim - trims white space characters from the left of the string or rtim - trims from the right). Read the manual for more details and options.

If you are not quite sure what those characters are, you can find out with this little helper.

$characters = preg_split( '//', $my_string );
foreach ( $characters as $character ) {
echo "ASCI value of the character {$character} is: " . ord ( $character ) . "<br />\n";
}

Then you can look up the values in a ASCI table.

Try:

$string_as_array = explode("\n", $string);

echo "<pre>";
print_r($string_as_array);
echo "</pre>";

The array that you get will contain segments of the string that is separated
with \n. Let me know if that helps.

Subject: [PHP] help with \n\r in strings

Hi all,

I receive a text file with a whole bunch of strings. and each line is
terminated by what I presume is \n\r however when I read the string into
PHP, it seems that the last column of the row and the first column of
the next row are connected but it appears as a space but I've done all
kinds of tests like $spacePos = strrpos($dateAmount, ' '); but this is
always empty.

So is there a way to test for \r\n? or what else can I use to delimit
these two values (last column of row and first column of next row)?

Thanks in advance.

Angelo
