在PHP函数内部的HTML标签中插入PHP变量

Question

我觉得问这个很愚蠢，我想粘贴'id'，我从数据库检索，这是存储在$link变量到details=...>Read More.后的<a href>标签，但我似乎不能让它工作。

<p>
<?php 
$longString = $row['name'];
$link = $row['id'];
echo readMoreHelper($longString);
function readMoreHelper($story_desc, $chars = 100) {
$story_desc = substr($story_desc,0,$chars);  
$story_desc = substr($story_desc,0,strrpos($story_desc,' '));  
$story_desc = $story_desc." <a href='details.php?details=$link>Read More...</a>";  
return $story_desc;  
} 
?> 
</p>

需要将$link作为函数参数传递。

您还遗漏了href属性末尾的'。

echo readMoreHelper($longString, $link);
function readMoreHelper($story_desc, $link, $chars = 100) {
$story_desc = substr($story_desc,0,$chars);  
$story_desc = substr($story_desc,0,strrpos($story_desc,' '));  
$story_desc .= " <a href='details.php?details=$link'>Read More...</a>";  
return $story_desc;  
}
