PHP file function

[ryandoss]

I feel ridiculous for having to ask this but I just can't figure out what the issue is!

 

The if statement below simply does not EVER return true.

 

$lines = file('file.txt');
foreach($lines as $line)
{
if($line == "--")
{
	// Do Work
}
}

 

The text file as follows:

Lothian
343,463
259,548
265,561
--
Mahaw
539,32
480,36
451,42
--
Rheged
413,724
504,762
495,772

 

I've changed the "--" to several other characters like a empty line or the word "new" and even :: or ||

 

What am I missing here? lol

try adding $line = trim($line); before the if, and if that does't help do a vardump on $line and see what each line contains. I think it might contain the new line character, and trim should remove it.

Ahhh yes of course!.. I tried "--\n" but I guess it doesn't work like that lol!

 

Thanks so much : )

The reason "--\n" didn't work is most likely because the text file in question was made by a Windows application. Since Windows uses "\r\n" for newlines, well... I don't think I need to explain further.

That's why you'll always want to use trim () on content you get from file (), unless it's important that you preserve newlines exactly as they are.
