How can I echo it properly? HTML+PHP issue : <p>I have a problem with this line,is there any solution for a line which must contain both single and double quotation marks?</p>

<pre><code>echo "&lt;a href='/ad/.$row['id_ad']'&gt;".$row['title']; 
</code></pre>

<p>I get this error:</p>

<pre><code>Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting '-' or identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING)
</code></pre>
