Question

I am trying to create a text file with PHP in fopen("test.txt","a"). I have also tried with fopen("test.txt","w+").

The text file is created but I want to check for some string in test.text, that it exist or in test.txt it will not create duplicate entry. Can someone help me out?

Use this code:

$content = file_get_contents('test.txt');
if (str_pos('YOUR KEYWORD', $content) !== false){
// your keyword exists in the file
}
