php - Displaying puncuation in button data attribute

Question

I'm trying to put a php variable in a button data attribute however weird characters are showing up instead of the punctuation. As an example instead of an apostraphe ' is showing up instead. The variable is normal everywhere else on the page. How can I fix this?

<button id="coolButton"data-name="<?PHP echo $name;?>"

Answer 1

id の末尾と data-name の先頭の間にはスペースが必要です

<button id="coolButton" data-name="<?PHP echo $name;?>"
