PHP - 在echo语句中缺少onClick输出的输出

Question

echo"<div class='btn-likes'><input type='button' title='".ucwords($str_like)."' class='".$str_like."' onClick='addLikes(".$tutorial['id'].",".$str_like.")' /></div>";

Output from above code is :

<input title="Like" class="like" onclick="addLikes(51,like)" type="button">

Output what I want is :

<input title="Like" class="like" onclick="addLikes(51,'like')" type="button">

apostrophe is missing in onclick="addLikes(51,'like')"

I have try :

echo"<div class='btn-likes'><input type='button' title='".ucwords($str_like)."' class='".$str_like."' 
          onClick='addLikes(".$tutorial['id'].",'".$str_like."')' /></div>";

And the output is so viewy :

<input title="Like" class="like" onclick="addLikes(51," like')'="" type="button">

Anyone can help me ?

You need to escape the quotes:

echo '<div class="btn-likes"><input type="button" 
    title="'.ucwords($str_like).'" class="'.$str_like.'" 
    onClick="addLikes('.$tutorial['id'].',\''.$str_like.'\')" /></div>';
