file() as array

[pjdowson]

Hi All,

I have an issue trying to pull an array from a text file containing simple names on each line. The problem is that the foreach does not parse the array created by file() but does when I just created an array().

I have included the code below.

Anyone know how to get around this?

Thanks

---- contents of colors.txt ----
blue
yellow
red
---- contents of colors.txt ----

<?
//This creates the array, but doesnt work when parsed
$lines = file('colors.txt');

//This works great, but why doesnt file()
$lines = array('blue', 'yellow', 'red');

$test = "yellow";

//This should output the word yellow
foreach ($lines as $value) {
   if($value == $test) {
   	 echo $value."<br />\n";
   	 }
}
?>

Read the PHP Manual on [man]file/man

You would notice that the new line sequence is still left in the array element.
As such, the correct code is:

<?php
$lines = file('colors.txt');

$test = "yellow";

//This should output the word yellow
foreach ($lines as $value) {
	if(rtrim($value) == $test) {
		echo $test . "<br />\n";
	}
}
?>
