Code language: PHP (php)

2 function stops reading the file once the

feof ( resource $stream ) : bool
Code language: PHP (php)

8 number of bytes has been read or the end of file (EOF) has been reached.

To check if the file pointer is at end of file, you can pass it to the

fgets ( resource $handle , int $length = ? ) : string|false
Code language: PHP (php)

4 function:

feof ( resource $stream ) : bool
Code language: PHP (php)

The

fgets ( resource $handle , int $length = ? ) : string|false
Code language: PHP (php)

4 function returns

fgets ( resource $handle , int $length = ? ) : string|false
Code language: PHP (php)

6 if the

feof ( resource $stream ) : bool
Code language: PHP (php)

6 is at the EOF or an error occurs. Otherwise, it returns

fgets ( resource $handle , int $length = ? ) : string|false
Code language: PHP (php)

1.

To read a file line by line, you use the

fgets ( resource $handle , int $length = ? ) : string|false
Code language: PHP (php)

9 function:

fgets ( resource $handle , int $length = ? ) : string|false
Code language: PHP (php)

Like the

feof ( resource $stream ) : bool
Code language: PHP (php)

2 function, the

fgets ( resource $handle , int $length = ? ) : string|false
Code language: PHP (php)

9 function accepts a file system pointer resource and up to a number of bytes to read. If you omit the

feof ( resource $stream ) : bool
Code language: PHP (php)

8 argument, the

feof ( resource $stream ) : bool
Code language: PHP (php)

2 function will read the entire line.

PHP read file examples

Let’s take some examples of how to read a file.

1) Read the entire file into a string

Suppose that you have a file named

1 New York New York 8,253,213 2 Los Angeles California 3,970,219 3 Chicago Illinois 2,677,643 4 Houston Texas 2,316,120 5 Phoenix Arizona 1,708,127 6 Philadelphia Pennsylvania 1,578,487 7 San Antonio Texas 1,567,118 8 San Diego California 1,422,420 9 Dallas Texas 1,343,266 10 San Jose California 1,013,616

Code language: plaintext (plaintext)

4 located at

1 New York New York 8,253,213 2 Los Angeles California 3,970,219 3 Chicago Illinois 2,677,643 4 Houston Texas 2,316,120 5 Phoenix Arizona 1,708,127 6 Philadelphia Pennsylvania 1,578,487 7 San Antonio Texas 1,567,118 8 San Diego California 1,422,420 9 Dallas Texas 1,343,266 10 San Jose California 1,013,616

Code language: plaintext (plaintext)

5 directory with the following contents:

1 New York New York 8,253,213 2 Los Angeles California 3,970,219 3 Chicago Illinois 2,677,643 4 Houston Texas 2,316,120 5 Phoenix Arizona 1,708,127 6 Philadelphia Pennsylvania 1,578,487 7 San Antonio Texas 1,567,118 8 San Diego California 1,422,420 9 Dallas Texas 1,343,266 10 San Jose California 1,013,616

Code language: plaintext (plaintext)

The following example uses the

feof ( resource $stream ) : bool
Code language: PHP (php)

2 function to read the contents of the entire

1 New York New York 8,253,213 2 Los Angeles California 3,970,219 3 Chicago Illinois 2,677,643 4 Houston Texas 2,316,120 5 Phoenix Arizona 1,708,127 6 Philadelphia Pennsylvania 1,578,487 7 San Antonio Texas 1,567,118 8 San Diego California 1,422,420 9 Dallas Texas 1,343,266 10 San Jose California 1,013,616

Code language: plaintext (plaintext)

4 file into a string and shows it on the webpage:

<?php

$filename = './public/population.txt';
$f = fopen($filename, 'r');

if ($f) {
    $contents = fread($f, filesize($filename));
    fclose($f);
    echo nl2br($contents);
}

Code language: HTML, XML (xml)

How it works.

First, open the

1 New York New York 8,253,213 2 Los Angeles California 3,970,219 3 Chicago Illinois 2,677,643 4 Houston Texas 2,316,120 5 Phoenix Arizona 1,708,127 6 Philadelphia Pennsylvania 1,578,487 7 San Antonio Texas 1,567,118 8 San Diego California 1,422,420 9 Dallas Texas 1,343,266 10 San Jose California 1,013,616

Code language: plaintext (plaintext)

4 file using the

feof ( resource $stream ) : bool
Code language: PHP (php)

1 function:

$f = fopen($filename, 'r');
Code language: PHP (php)

Second, read the contents of the entire file using the

feof ( resource $stream ) : bool
Code language: PHP (php)

2 function; use the

<?php

$filename = './public/population.txt';
$f = fopen($filename, 'r');

if ($f) {
    $contents = fread($f, filesize($filename));
    fclose($f);
    echo nl2br($contents);
}

Code language: HTML, XML (xml)

1 function to get the size of the file:

$contents = fread($f, filesize($filename));
Code language: PHP (php)

Third, show the contents of the file on a web page; use the

<?php

$filename = './public/population.txt';
$f = fopen($filename, 'r');

if ($f) {
    $contents = fread($f, filesize($filename));
    fclose($f);
    echo nl2br($contents);
}

Code language: HTML, XML (xml)

2 function to convert the newline characters to

<?php

$filename = './public/population.txt';
$f = fopen($filename, 'r');

if ($f) {
    $contents = fread($f, filesize($filename));
    fclose($f);
    echo nl2br($contents);
}

Code language: HTML, XML (xml)

3 tags.

echo nl2br($contents);
Code language: PHP (php)

Finally, close the file using the

feof ( resource $stream ) : bool
Code language: PHP (php)

3 function.

Note that the

<?php

$filename = './public/population.txt';
$f = fopen($filename, 'r');

if ($f) {
    $contents = fread($f, filesize($filename));
    fclose($f);
    echo nl2br($contents);
}

Code language: HTML, XML (xml)

5 function is a shortcut for opening a file, reading the whole file’s contents into a string, and close it.

2) Read some characters from a file

To read some characters from a file, you specify the number of bytes to read. The following example uses the

feof ( resource $stream ) : bool
Code language: PHP (php)

2 function to read up to 100 bytes from the

1 New York New York 8,253,213 2 Los Angeles California 3,970,219 3 Chicago Illinois 2,677,643 4 Houston Texas 2,316,120 5 Phoenix Arizona 1,708,127 6 Philadelphia Pennsylvania 1,578,487 7 San Antonio Texas 1,567,118 8 San Diego California 1,422,420 9 Dallas Texas 1,343,266 10 San Jose California 1,013,616
