When i run the script, all it does echo only.

its show me this

it seem like its skiping unset().

so far all i kno that if i remove the if statment it will work.

but i need the if statment to do what i have planed.

view source on your output'd page, I bet each line is on a seperate line in the html output

most likely, "JoJo" isnt matching because what you are getting from the file(); is "JoJo\n"

just a guess... but I seem to recall all file functions returning EOL also

[Quest]

nothing...

[tekky]

just for double checking

echo nl2br($file[$n]);

[Quest]

but, do u see what i'm trying to do? is there any other way?

[tekky]

testing it now, and yes

<?php 
$file = file("here.txt"); 
$c = count($file); 

for($n=0;$n<$c;$n++)
{ 
	$file[$n] = trim($file[$n]); //strip any whitespace chars
	if($file[$n]=="JoJo"){ 
		unset($file[$n]);
	}
	else
	{ 
		echo $file[$n]."<BR>";
	}
} 
echo $c; 
?> 

I was right, it was extra ctrl codes from the file read for carriage return line feed interefereing with the if check, trim() removes them

[Quest]

i think, it might have something to do what the if statment. but i dont see why it is the cuase. thanks for helping me

[Quest]

oh, thanks you!, it works. but what was the problem?

[Quest]

i see, thanks
