can strpos() find the line number of the txt

[ted_chou12]

what I see in the strpos() function is that the place of the letter gets echoed out, but is it possible, or are there are there other functions that echo out the line number of that specific string?
Thanks
Ted

You would need to make your own function for this. Use [url=http://php.net/file]file[/url] to pull a file into an array, then use [url=http://php.net/array_ keys]array_keys[/url] to find the line number.

$lines = explode("\n", $file_text);

[trq]

[quote]$lines = explode("\n", $file_text);[/quote]

Why would you do that when...

[code=php:0]
$lines = file($file_text);
[/code]

is more efficient?

I was just trying to explain to him in one line how line numbers are created
