I'm beginner in PHP. I want to write some numbers in the .txt file. I wrote this code in phpstorm program:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
<?php
$l=5;
$a = fopen("./mmm.txt", "w");
for ($m = 1;$m <=3 ; $m++) {
for ($j = 1; $j <= 2 ^ $m; $j++) {
for ($i = 1; $i <= $l - $m; $i++) {
fwrite($a,$j * 2 ^ ($i - 1));
}
}
}
fclose($a);
?>
</body>
</html>
When I run this code in Mozilla Firefox, I face with these errors: Allowed memory size of 134217728 bytes exhausted (tried to allocate 36 bytes) in... or Maximum execution time of 120 seconds exceeded in...
and the size of mmm.txt file is approximately 138000 KB. what is wrong?
