PHP If语句带有特殊字符

Question

How can i create an If Statement or Function that if finds the special character '}' then in the next character will put a <br>?

$myfile = fopen("result.txt", "r") or die("Unable to open file!");

while(!feof($myfile)) {
    echo fgetc($myfile);
}
fclose($myfile);

Answer 1

You can just read the contents of the file and then do a replacement.

$contents = file_get_contents('file.txt');
$contents = str_replace('}', '}<br>', $contents);
echo $contents;

If you just want a newline after the closing curly brace then just change the line to:

$contents = str_replace('}', "}
", $contents);

If you want to save it again then you can do it like this:

if ( ! file_put_contents('file.txt', $contents)) {
    echo 'Error. File could not be saved!';
}
