Ignore break line with str_replace

The code below will replace certain text. Actually I get the $str data from a text file with file_get_contents so please imagine there's a new line in the $str.

$str = 'From: My Name <myemail@myname.com>
        To: storm@yahoo.com
        Message-ID: <1638618225.203837.1426581391642.JavaMail.yahoo@mail.yahoo.com>';

$old = array("My Name", "To: storm@yahoo.com");
$new   = array("New Name", "");
echo str_replace($old, $new, $str );

Output: 

From: New Name 

Message-ID: <1638618225.203837.1426581391642.JavaMail.yahoo@mail.yahoo.com>

Unfortunately after removing To: storm@yahoo.com, the code will create a line break. How can I use str_replace without creating new break line?

Solution

  • Like you said you get this from a text file and if what you show is what is in the text file then it is not creating a newline character, it is actually you that is not removing the already existing new line.

    Try 

    $str = 'From: My Name <myemail@myname.com>
        To: storm@yahoo.com
        Message-ID: <1638618225.203837.1426581391642.JavaMail.yahoo@mail.yahoo.com>';

$old = array("My Name", "To: storm@yahoo.com\n");
$new = array("New Name", "");
