I have a string with multiple newlines.
The String:
This is a dummy text. I need
to format
this.
Desired Output:
This is a dummy text. I need to format this.
I'm using this:
$replacer = array("\r\n", "\n", "\r", "\t", " ");
$string = str_replace($replacer, "", $string);
But it is not working as desired/required. Some of the words don't have spaces between them.
Actually I need to convert the string with all the words separated by single spaces.
I would encourage you to use preg_replace:
# string(45) "This is a dummy text . I need to format this."
$str = preg_replace( "/\s+/", " ", $str );

You may have noted in the " . " portion of the first example. Spaces that are immediately followed by punctuation should probably be removed entirely. A quick modification permits this:
$patterns = array("/\s+/", "/\s([?.!])/");
$replacer = array(" ","$1");
# string(44) "This is a dummy text. I need to format this."
$str = preg_replace( $patterns, $replacer, $str );
