You can declare new array in PHP by using the code below:

$new_array = array();

Here’s a good one

$pattern = "/as+hrefs*=s*['\"]?([^'\">]+)['\"]?>([^<]*)</ie";
$replacement = "'a href=\"$1'.strtolower(str_replace(' ', '', '$2')).'\">$2<'";
$string = preg_replace($pattern, $replacement, $string);

The pattern says to find:

1. ‘a href‘ — there must be at least one space in between the ‘a’ and the ‘href‘ ( \s+ ),
2. followed by zero or more spaces( \s* ),
3. followed by the equal sign ( = ),
4. followed by zero or more spaces ( \s* ),
5. followed by an optional single quotation mark or double quotation mark ( ['\"]? ),
6. followed by one or more of anything that is not a single quotation mark, a double quotation mark or an end element marker and capture this subpattern by using parentheses ( ([^'\">]+) ),
7. followed by an optional closing single quotation mark or double quotation mark ( ['\"]? ),
8. followed by a closing element marker ( > ),
9. followed by zero or more of anything that is not an opening element marker ( ([^<]*) ),
10. followed by an opening element marker.

Here’s a nice tutorial:

Some mail clients cannot understand HTML emails. Therefore it is best to send any HTML email using a multipart construction, where one part contains a plain-text version of the email and the other part is HTML. If your customers have HTML email turned off, they will still get a nice email, even if they don’t get all of the HTML markup. Have a look at the example:

Here’s how to upload files using curl in php: (it’s very easy)

notice the @ infront of the file path, this is the magic part.

<?php
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_VERBOSE, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
    curl_setopt($ch, CURLOPT_URL, _VIRUS_SCAN_URL);
    curl_setopt($ch, CURLOPT_POST, true);
    // same as <input type="file" name="file_box">
    $post = array(
        "file_box"=>"@/path/to/myfile.jpg",
    );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    $response = curl_exec($ch);
?>

<?php
// Permanent redirection
header(“HTTP/1.1 301 Moved Permanently”);
header(“Location: http://www.website.com/”);
exit();
?>

$blogusers = $wpdb->get_results( “SELECT user_id, user_login, display_name, user_email, meta_value FROM wp_users, wp_usermeta WHERE wp_users.ID = wp_usermeta.user_id AND meta_key = ‘wp_1_capabilities’ and wp_users.ID=1″ );

$t = @unserialize( $blogusers[0]->meta_value );

if($t["editor"] == 1)

{

}

Just make a code for importing Mochimedia game feed.

It will import the feed by creating post, add tag, insert into category, and schedule it dailly. It is using wordpress technology. You need to put these files in wp root.

Download it here.

<?php
$path = getcwd();
echo $path;
?>

For Recurring Payments Notifications, you can use IPN. Merchants are notified of certain events through IPN. For recurring payments profiles created using Express Checkout, buyers are also notified of specific events by email.

To activate the IPN, you need to login to your account and activate it from “Instant Payment Notification Preferences” Menu.

Once payment, subscription started, or subscription ended it will execute the url you entered in IPN setting.

Here are the request from paypal for recurring payment:

There are two variable you need to check txn_type and subscr_id.

You can see that txn_type can be subscr_payment, subscr_signup, and subscr_cancel
