fgets() function in PHP
The fgets() function returns a line from a file. It returns a string of up to length - 1 bytes read from the file pointed to by file_pointer.
Syntax
fgets (file_pointer, length);
Parameters
file_pointer − The file pointer must be valid, and must point to a file successfully opened by fopen() or fsockopen().
length − Reading ends when length - 1 bytes have been read, on a newline, or on EOF (whichever comes first).
Return
The fgets() function returns a string of up to length - 1 bytes read from the file pointed to by fle_pointer.
Example
The following is an example. Here, we have a file “one.txt” with text “This is it!”.
<?php
$file_pointer = @fopen("/new/one.txt", "w");
if ($file_pointer) {
while (!feof($file_pointer)) {
$buffer = fgets($file_pointer, 512);
echo $buffer;
}
fclose($file_pointer);
}
?>Output
This is it!
Let us see another example.
Example
Here, we have a text file “new.txt”, with the text, “This is demo text”.
<?php
$file_pointer = fopen("new.txt","r");
$res = fgets($file_pointer);
echo $res;
fclose($file_pointer);
