    <p>PHP has a built - in function, array_slice() , that you can use to extract a range of elements from an array. To use it, pass it the array to extract the slice from, followed by the position of the first element in the range (counting from zero), followed by the number of elements to extract. The function returns a new array containing copies of the elements you extracted (it doesn ’ t touch the original array). For example:</p> <pre><code>$authors = array( “Steinbeck”, “Kafka”, “Tolkien”, “Dickens” ); $authorsSlice = array_slice( $authors, 1, 2 ); // Displays “Array ( [0] = &gt; Kafka [1] = &gt; Tolkien )” print_r( $authorsSlice ); </code></pre> <p>By the way, if you leave out the third argument to array_slice() , the function extracts all elements from the start position to the end of the array:</p> <pre><code>$authors = array( “Steinbeck”, “Kafka”, “Tolkien”, “Dickens” ); $authorsSlice = array_slice( $authors, 1 ); // Displays “Array ( [0] = &gt; Kafka [1] = &gt; Tolkien [2] = &gt; Dickens )”; print_r( $authorsSlice ); </code></pre> <p>Earlier you learned that array_slice() doesn ’ t preserve the indices of elements taken from an indexed array. If you want to preserve the indices, you can pass a fourth argument, true , to array_slice() :</p> <pre><code>$authors = array( “Steinbeck”, “Kafka”, “Tolkien”, “Dickens” ); // Displays “Array ( [0] = &gt; Tolkien [1] = &gt; Dickens )”; print_r( array_slice( $authors, 2, 2 ) ); // Displays “Array ( [2] = &gt; Tolkien [3] = &gt; Dickens )”; print_r( array_slice( $authors, 2, 2, true ) ); </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.
