SharePoint 2007 Web Parts and Configuration Quiz

The headers_sent() function specifically checks whether HTTP headers have already been sent. header() sends headers, setcookie() also sends headers (cookies use HTTP headers), and sent() is not a valid PHP function for this purpose.

addslashes() escapes single quotes by adding a backslash before them, converting ' to '. The other options are not valid PHP functions - appendslashs(), addbackslash(), and removeslash() do not exist in PHP's string function library.

The file() function reads a file into an array where each element corresponds to a line in the file. file_read() and read() are not standard PHP file-reading functions, and array() is a language construct for creating arrays, not reading files.

strcspn() returns the length of the initial segment of the first string that does NOT contain any characters from the second string - effectively finding the first position with a character not in the other string. It does not perform glob matching or find ASCII minimum positions.

unlink() is the PHP function used to delete files. delete_file(), delete(), and remove() are not standard PHP file deletion functions - these might exist in other languages but not in PHP's filesystem functions.

Page Viewer Web Part displays external content in an iframe, making it ideal for showing external applications on SharePoint pages. Content Editor is for static HTML, Content Query queries SharePoint content, and External Applications Web Part is not a standard SharePoint 2007 web part.

SharePoint 2007 supports three authentication methods: NTLM (Windows integrated), Kerberos (for single sign-on), and Forms-based authentication (for custom login). All three are valid options.

The ghosting/unghosting terminology originated in SPS 2003 to describe whether pages were stored in the database (unghosted) or on the file system (ghosted). Later versions use customized/uncustomized instead.

Alerts are the built-in feature for sending email notifications when list items are inserted or updated. Event handlers and workflows require custom development, and Timer Jobs are for scheduled tasks, not immediate notifications.

Events ending in -ed (ItemDeleted, ItemUpdated) are asynchronous and fire after the action completes. Events ending in -ing (ItemDeleting, ItemUpdating) are synchronous and fire before the action, allowing cancellation.

In SharePoint, workflows are event-driven actions that respond to item-level changes. They can be triggered from Content Types, List Items, and Document Library items, but NOT from Site Columns. Site Columns are reusable column definitions that themselves don't fire workflow events - they're templates used to define columns across lists and libraries.

Adding ?contents=1 to a SharePoint page URL displays the page in a special diagnostic view that reveals all web parts. This mode shows web part zones, boundaries, and properties to help with debugging and page layout. The question mark (?) indicates it's a query string parameter, not a hash fragment (#) which points to page anchors.

The Page Viewer Web Part is specifically designed to embed external web content within a SharePoint page using an iframe. Content Editor Web Part is for HTML/JavaScript snippets, Content Query Web Part queries and displays SharePoint content, and there is no standard 'External Application Web Part' in SharePoint's web part collection.
