echo $num.”<BR>”;. At the beginning of each iteration, the condition is tested. echo “<tr>\n <td align = right>$distance</td>\n”;. echo “ <td align = right>. $distance / 10 .”</td>\n</tr>\n”;.

echo “$product - $price<br>”;. One thing to note when using each() is that the array keeps track of the current element. If we want to use the array twice in the same script, we need to set the current element back to the start of the array using the function reset. This sets the current element back to the start...

Alternatively, we can use the array_reverse() function to reverse the array created by. Note that array_reverse() returns a modified copy of the array. In Chapter 2, “Storing and Retrieving Data,” we stored customer orders in a file. Each line in the file looks something like. To process or fulfill this order, we could load it back into an array. $number_of_orders...

<p>Your feedback has been sent.</p>. We have omitted this from the script and other examples for the sake of brevity.. The first three parameters are compulsory and represent the address to send email to, the sub- ject line, and the message contents, respectively. Valid email headers are described in the document RFC822, which is available online if you want more...

For example, strcmp() would order the string “2” as greater than the string “12” because it is lexicographically greater. You can read more about natural ordering at http://www.linuxcare.com.au/. For example, strlen(“hello”) returns 5. This can be used for validating input data. By my reasoning, the minimum length of an email address is six characters—for example,. We will look at better...

Passing a parameter allowed us to get data that was created outside the function—in this case, the array $data —into the function.. We can improve our create_table() function in many ways, but one way might be to allow the caller to specify the border or other attributes of the table. Here is an improved version of the function. echo “<table...
