Body
As has been mentioned by others, a forward slash is not a special character inside a string, in PHP or in Javascript (and since JSON is derived from Javascript it follows the same rules for string interpolation). However if you were reading some JSON, you could be forgiven for thinking that it is (although you should always RTM ;-) ). The reason you think you need to escape the slash is due to a subtle difference in the way PHP and Javascript interpolate superfluous forward slashes. Consider the following string declaration, valid in both PHP and Javascript: <pre><code>"AC\/DC" </code></pre> In PHP, the extra backslash is treated as a literal, so: <pre><code>echo "AC\/DC"; // outputs AC\/DC </code></pre> In Javascript, the extra backslash is dropped, so: <pre><code>console.log("AC\/DC"); // logs AC/DC </code></pre> JSON mandates the escaping of forward slashes, but <a href="http://php.net/json-encode" rel="nofollow noreferrer"><code>json_encode()</code></a> will take care of this escaping for you. You do not need to add the backslashes to the string yourself. And because of the difference in the way these additional backslashes are interpolated, you cannot simply take a JSON string and drop it into your PHP source - because it will will be interpretted as a different value. <a href="http://php.net/json-encode#refsect1-function.json-encode-changelog" rel="nofollow noreferrer">Since PHP 5.4.0</a> you can supply the <code>JSON_UNESCAPED_SLASHES</code> flag to <code>json_encode()</code> in PHP to prevent it from adding the backslashes. However this is unnecessary and may cause a strict JSON parser to reject the data. So to sum up, the correct way to declare your string in PHP is: <pre><code>$path["file_name"] = "www.119.com/assets/demo/large/".$row["file_name"]; </code></pre> As a side note, you probably also what to include <code>http://</code> at the beginning of the string and pass <code>$row['file_name']</code> through <a href="http://php.net/urlencode" rel="nofollow noreferrer"><code>urlencode()</code></a> as well, since the data appears to be a URL: <pre><code>$path["file_name"] = "http://www.119.com/assets/demo/large/".urlencode($row["file_name"]); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
