Answer 1

你错过了回音中的美元符号

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

顺便说一句，有很多SO链接有类似的问题：

• Can't remove dashes (-) from string
• Can't remove special characters with str_replace
• 还有更多....

它工作正常。请参考下面的代码。

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

试试这个工作正常

        $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;

结果

HelloSeeThisIsWorking
Hello See This Is Working
Hello See This Is Working
