Question

i have a text file with colors in it. The script only returns true if orange is selected. What in the world am i missing?

$filename="colors.txt";
$words=file($filename);
shuffle($words);
$word=$words[0];


if ( $word == "yellow" ){$pid = '558';}
else if ( $word == "red" ){$pid = '557';} 
else if ( $word == "purple" ){$pid = '556';}
else if ( $word == "orange" ){$pid = '555';} 
else if ( $word == "green" ){$pid = '554';}
else if ( $word == "brown" ){$pid = '553';}
else if ( $word == "blue" ){$pid = '552';}
else {$pid = 'poop';}

echo $word;
echo $pid;

Answer 1

The “orange” line, being the last in the file, doesn’t have a line ending “\r\n”.

Form the documentation for file():

Each line in the resulting array will include the line ending, unless FILE_IGNORE_NEW_LINES is used, so you still need to use rtrim() if you do not want the line ending present.
