    <p>I'm trying to save a string and the data is coming in with stuff that I don't want at the end of an array.</p> <pre><code>["bunch", "of", "stuff"]unwantedtext </code></pre> <p>I'm struggling with getting rid of everything after the closing bracket. This is my latest attempt. I end up with an empty file.</p> <pre><code>$toPost = substr($str, 0, strrpos($str, '\]')); </code></pre> <p>Perhaps my escape isn't working correctly? I've also tried doublequotes.</p> <p>Here's an update to the original question.</p> <p>This is my Javascript function:</p> <pre><code>goalChange = function() { var i, key, len, postThis; key = void 0; postThis = {}; i = 0; len = localStorage.length; while (i &lt; len) { key = localStorage.key(i); postThis[key] = "" + localStorage.getItem(key); i++; } postThis.goals = localStorage.getItem("goals"); postThis.userid = username; return $.ajax({ url: "goalChange.php", type: "POST", data: postThis, success: function(response, textStatus, jqXHR) { return console.log("Yay, the save worked!"); }, error: function(jqXHR, textStatus, errorThrown) { return console.log("Didn't work so good..."); } }); }; </code></pre> <p>Here's the PHP file:</p> <pre><code>&lt;? if ($_POST) { $user = $_POST['userid']; // ADDED THIS LINE AND CHANGED NEXT TO GET STUFF INTO THE USERS OWN FILE $logFile = dirname($_SERVER['SCRIPT_FILENAME']) . "/" . $user . ".json"; if (!file_exists($logFile)) { touch($logFile); chmod($logFile, 0777); } $newStr = ($_POST); $str = str_replace('\\', '', $newStr); $toPost = substr($str, 0, strrpos($str, ']')); file_put_contents($logFile, $toPost); echo "OK"; return; } </code></pre> <p>I need to use the userid to save the file with the correct name. That's working, but the file is getting the userid added to the end of the array that I want to keep.</p> <p>Thanks for the help.</p>

    1. COI would look into how that unwanted text is getting there in the first place. Fix the problem, don't make a workaround.

    2. CO@JustinWood Yeah that's my plan, but I got curious about figuring out how to use strrpos and got my self stumped on this side issue. Once I saw that the available questions/answers here didn't hit on this exact problem it might be worth having answered.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
