PHP Append to File - fwrite() :
The PHP fwrite() function is used to write and append data into file.
<?php //open file in append mode $fp = fopen('data.txt', 'a'); //writing data to file fwrite($fp, ' today is great day '); fwrite($fp, 'but it is raining'); //closing file fclose($fp); echo "File appended successfully"; ?>Output:
welcome to skptricks today is great day but it is raining
NOTE : make sure while appending the data to file, you must open file in append mode. Otherwise it will erase the previous content/data of file.
