The idea is as follows: use file_get_contents() to get the contents of the txt file, and then use explode() to convert the obtained string into an array. To get the length of an array, use the count() function.
PHP Code

Copy code The code is as follows:

$file = '2010-12-15.txt';
$content = file_get_contents($file);
//echo $content;
$array = explode("\r\n", $content);
//print_r($array);
for($i=0; $i〈count($array); $i++)
{
echo $array[ $i].'〈br /〉';
}

About the line breaks in txt documents
In regular expressions, there is a \n that means newline, and there is another \r that means carriage return (this is it Resulting in the idiot Chinese translation "carriage return") meaning. When processing String or console output, no matter which one you bring, you can wrap the line.
But in txt, none of them are standard line breaks. Only the combined \r\n is a line break (this is true for the default line breaks in the entire Windows).
It means\rPressing Enter indicates that the line is over, the cursor returns to the beginning, and then\nmoves down one line to create a new line.
Because of this, when I used scanner() to search txt documents with regular expressions, I was at a loss and couldn't find the problem at all.
About file_get_contents()
The file_get_contents() function reads the entire file into a string.
The file_get_contents() function is the preferred method for reading the contents of a file into a string. If supported by the operating system, memory mapping technology is also used to enhance performance.

The above introduces the code for PHP to read the contents of the txt file and assign it to an array, including the content of the txt e-book for free download, the complete set, and hope that friends who are interested in PHP tutorials Helps.
