Number of lines in a file?

Other than iterating through each line and incrementing a counter (seems too resource-intensive), how can I find out how many lines are in a certain file?

Code:

---

$file = file('yourfile');
$x = count($file);

echo $x . ' lines in the file.'

---

Or something to that extent.

Cool :)

BTW...

PHP Code:

---

echo $x . ' lines in the file.' 


---

...can be replaced with...

PHP Code:

---

echo "$x lines in the file." 


---

ah, nice to know. :)

Code:

---

//I should use the php tags, huh?
$file = file('yourfile');
$x = count($file);

echo $x . ' lines in the file.'

---

could probably be replace with:

Code:

---

echo count(file('yourfile')) . ' lines in the file.'

---

Althought I haven't tried it

Probably could, very C++/Java-like if it works :)

FYI, just tried it. Works like a charm. :)
