PHP continue Statement

Description

Sometimes a situation arises where we want to take the control to the beginning of the loop (for example for, while, do while etc.) skipping the rest statements inside the loop which have not yet been executed.

The keyword continue allow us to do this. When the keyword continue executed inside a loop the control automatically passes to the beginning of loop. Continue is usually associated with the if.

Example:

In the following example, the list of odd numbers between 1 to 10 have printed. In the while loop we test the remainder (here $x%2) of every number, if the remainder is 0 then it becomes an even number and to avoid printing of even numbers continue statement is immediately used and the control passes to the beginning of the loop.

<?php
$x=1;
echo 'List of odd numbers between 1 to 10 <br />';
while ($x<=10)
{
if (($x % 2)==0)
{
$x++;
continue;
}
else
{
echo $x.'<br />';
$x++;
}
}

Output

List of odd numbers between 1 to 10
1
3
5
7
9

PHP: Tips of the Day

PHP: Convert one date format into another in PHP

The second parameter to date() needs to be a proper timestamp (seconds since January 1, 1970). You are passing a string, which date() can't recognize.

You can use strtotime() to convert a date string into a timestamp. However, even strtotime() doesn't recognize the y-m-d-h-i-s format.

PHP 5.3 and up

Use DateTime::createFromFormat. It allows you to specify an exact mask - using the date() syntax - to parse incoming string dates with.

PHP 5.2 and lower

You will have to parse the elements (year, month, day, hour, minute, second) manually using substr() and hand the results to mktime() that will build you a timestamp.

But that's a lot of work! I recommend using a different format that strftime() can understand. strftime() understands any date input short of the next time joe will slip on the ice. for example, this works:

$old_date = date('l, F d y h:i:s');         // returns Saturday, January 30 10 02:06:34
$old_date_timestamp = strtotime($old_date);
$new_date = date('Y-m-d H:i:s', $old_date_timestamp);
