This is possible in php we remove this..

You are missing the dollarsign in your echo

$string="how-3981-make-scarecrow";
$test = str_replace("-", " ", $string);
echo $test;

By the way, there are a lots of SO links with similar questions:

• Can't remove dashes (-) from string
• Can't remove special characters with str_replace
• and many more....

It's working fine. Please refer to the code below.

echo $string = "how-3981-make-scarecrow";
$test = str_replace( "-", " ", $string );
echo $test;

Try this it is working fine

        $string="Hello-See-This-Is-Working";
        $result = str_replace("-", "", $string);
        echo $result;

        $string="Hello-See-This-Is-Working";
        $result = str_replace("-", " ", $string);
        echo $result;
        $string="Hello-See-This-Is-Working";
        $result = str_replace("-", "       ", $string);
        echo $result;

result

HelloSeeThisIsWorking
Hello See This Is Working
