    <p>I'm attempting to use PHP's CURL to make a GET request to a server and am having some difficulties doing so. When I make the request through PHP I am returned a 500 error from the external server. However, if I make the request using the bash curl, or visit the URL in a browser it succeeds.</p> <p>I've stripped the PHP down to the bare essentials:</p> <pre><code>$url = 'http://example.com:8080/path/to/service?cmd=my_command&amp;arg=example2.com'; $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_exec($ch); print_r(curl_getinfo($ch)); curl_close($ch); </code></pre> <p>As stated this returns a 500 error from example.com. However, if I do the following:</p> <pre><code>[me@host ~] curl "http://example.com:8080/path/to/service?cmd=my_command&amp;arg=example2.com" </code></pre> <p>I am returned the expected XML document.</p> <p>What gives? It's got to be something with the encoding of the URL, as if I strip the <code>$url</code> var down to just <code>http://example.com:8080</code> the PHP CURL request now responds with 200. I've tried replacing the <code>&amp;</code> with <code>%26</code> - that didn't work (nor would I expect it to, as <code>&amp;</code> is valid in the URL there). I've tried doing what the answer for <a href="https://stackoverflow.com/questions/10230774/php-curl-sending-vars-using-get-wierd-results">php curl sending vars using GET wierd results</a> suggested, but that didn't help either.</p> <p>What am I missing here? I'm sure that it's something absurdly simple, but it's escaping me.</p> <p>Thanks!</p> <p>EDIT: I've just attempted doing this in Python - just to see what happened - and it works fine there:</p> <pre><code>import urllib2 r = urllib2.urlopen(theURL) r.read() </code></pre>

    1. COCan you give us the output of curl_getinfo?

    2. COThere's nothing particularly interesting there; http_code is 500, redirect_count is 0, content_type is text/html;charset=iso-8859-1, and the url is the string I passed in. The rest of the data there is pretty much just transfer speed info.

    3. COYou're setting RETURNTRANSFER to 1 but not capturing the return value of `curl_exec`. Either turn off RETURNTRANSFER or assign the return value of `curl_exec` to a variable and `print_r` that.

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.
