Example 2 (If you want to create the file, we will use 'w' mode instead of 'r'):
<?php
$file=fopen("Newest.txt","w");
$str="This is same file with different text";
fputs($file,$str);
$file=fopen("Newest.txt","r");
while(!feof($file))
{
echo fgets($file)."<br/>";
}
?>
Output:
This is same file with different text
Example 3 (If you want to append some text into a file change the mode into 'a'):
<?php
$file=fopen("Newest.txt","a");
$str="This is same file with extra text which has been appended"; 0
fputs($file,$str);
$file=fopen("Newest.txt","r");
while(!feof($file)) 1
{
echo fgets($file)."<br/>";
} 2
?>
Output:
This is same file with different textThis is same file with extra text which has been appended 3
