PHP数据处理不输出

Question

Hi I am trying to get this external text file to print inside my php document. The code looks fine to me however when I echo it does not output anything and I am not sure why this is. Can anybody help me out as I am new to this.

$location = '/Applications/MAMP/htdocs/PHPLabs/branches.txt';
$fp = fopen($location, 'r');
if ($fp) {
$readin = fread($fp);
fclose($fp);
} else {
echo 'Can\'t open input.txt';
}

Not sure what you're trying to 'echo' but have you checked if the file exists in the first place?

Your code could be written as:

$location = '/Applications/MAMP/htdocs/PHPLabs/branches.txt';

if (file_exists($location) && $data = file_get_content($location)){
    echo $data;
} else {
  echo 'File not found';
}

---

if (file_exists($location) && $file = fopen($location, 'r')){
    $file_content = fread($file, filesize($location));
    fclose($file);
} esle {
    echo 'File not found';
}
