    <p>Trying to figure out how to pull values for a specific index in an array, manipulate it, then replace the value back into the array in its original position.</p> <p>I've got an array from a form POST that uploaded a CSV:</p> <pre><code>if(isset($_POST['submit'])){ $csvFile = $_FILES['csv']['tmp_name']; $handle = fopen($csvFile,"r"); $fileop = fgetcsv($handle,1000,","); } </code></pre> <p>Uploaded CSV file usually has 20 to 100 rows with 5 columns (indexed keys). Here's an example of only 2 records from a <code>print_r($fileop)</code> while loop.</p> <p>HTML Display:</p> <pre><code>Array ( [0] =&gt; Chevy [1] =&gt; Sedan [2] =&gt; Malibu [3] =&gt; &lt;a href="#"&gt;&lt;img href="http://www.domain.co/logo.png" alt="Pic" /&gt;&lt;/a&gt; [4] =&gt; 8000.00 ) Array ( [0] =&gt; Chevy [1] =&gt; Pickup [2] =&gt; 2500 [3] =&gt; &lt;a href="#"&gt;&lt;img href="http://www.domain.co/logo.png" alt="Pic" /&gt;&lt;/a&gt; [4] =&gt; 18000.00 ) </code></pre> <p>Here's some examples of what I'm trying to accomplish.</p> <p>EDIT #1:</p> <pre><code>$imageLink = stripslashes($fileop[3]); str_replace("http://www.domain.co/logo.png","/images/logo.png",$imageLink); </code></pre> <p>EDIT #2:</p> <pre><code>$model = stripslashes($fileop[2]); $preHTML = &lt;div id="model" style="clear:both"&gt;&lt;strong&gt;; $postHTML = &lt;/strong&gt;&lt;/div&gt;; $fullHTML = $preHTML . $model . $postHTML; </code></pre> <p>NEW HTML Display:</p> <pre><code>Array ( [0] =&gt; Chevy [1] =&gt; Sedan [2] =&gt; &lt;div id="model" style="clear:both"&gt;&lt;strong&gt;Malibu&lt;/strong&gt;&lt;/div&gt; [3] =&gt; &lt;a href="#"&gt;&lt;img href="/images/logo.png" alt="Pic" /&gt;&lt;/a&gt; [4] =&gt; 8000.00 ) Array ( [0] =&gt; Chevy [1] =&gt; Pickup [2] =&gt; &lt;div id="model" style="clear:both"&gt;&lt;strong&gt;2500&lt;/strong&gt;&lt;/div&gt; [3] =&gt; &lt;a href="#"&gt;&lt;img href="/images/logo.png" alt="Pic" /&gt;&lt;/a&gt; [4] =&gt; 18000.00 ) </code></pre> <p>BIG QUESTION: How do I return these manipulated values back to the array?</p> <p>I've been searching for a few hours on this and I'm overloaded now and more confused. Any help is much appreciated!</p> <p>UPDATE:</p> <p>I've been playing with some answers provided below and haven't had much luck so far. It does work as far as updating a single array in the "stacked" arrays that are retrieved from the CSV file but I can't get it to update all the arrays for a specific key and retain the "stacked" arrays.</p> <p>I'm not sure I'm using the right terminology for "stacked arrays" but basically if I loop thru the stacked arrays from the CSV I get many print outs of individual arrays so when it comes time to INSERT into MySQL DB, I can loop thru the arrays and write them in as individual records.</p> <p>I tried the following and it lost all the other arrays and only kept the 1st one that it modified:</p> <pre><code>while(($fileop = fgetcsv($handle,1000,",")) != false){ $model = stripslashes($fileop[2]); $fileop[2] = '&lt;div id="model" style="clear:both"&gt;&lt;strong&gt;'.$model.'&lt;/strong&gt;&lt;/div&gt;'; } </code></pre> <p>Now when doing the following print I don't get all the arrays:</p> <pre><code>&lt;pre&gt; &lt;?php while(($fileop = fgetcsv($handle,1000,",")) != false){ print_r($fileop); } ?&gt; &lt;/pre&gt; </code></pre> <p>HTML Result (Only 1 array, all other "stacked arrays" are lost and don't print):</p> <pre><code>Array ( [0] =&gt; Chevy [1] =&gt; Sedan [2] =&gt; Malibu [3] =&gt; &lt;a href="#"&gt;&lt;img href="http://www.domain.co/logo.png" alt="Pic" /&gt;&lt;/a&gt; [4] =&gt; 8000.00 ) </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.
