In the process of writing a report in Word, a few simple data summary tables are often involved in the document. Although the table rollup is Excel's strength, but if for a simple summary to use Ecxel, and Ecxel still need to constructor formula, also need to import export or consider data format problems, in fact, it is not convenient. In fact, by using the SUM function directly in a Word table, you can use left, right, ABOVE, below, and so on to make a single row subtotal, and mix these parame

is a faster method:($result, $value) { Array ())Because the array_merge function merges the arrays of the same string key names, you must first use the array_value fetch values and then merge them.If the second dimension is a numeric key name, such as:Array (Array ( ' A1 '), Array (Array (array ( ' A5 '),); So that's it for you:Array ())2 array_walk_recursive Function MethodWith the array_walk_recursive () function, it is very flexible to convert an array of any dimension into a one

Although you can reduce the size of a word file by compressing all the pictures or the size of the pictures in the Word2007 document, it is cumbersome to perform a compression operation each time.
