HTML to Text Conversion Functions



• array_flip -

                    This function is the opposite function for the get_html_translation_table() function by
reversing HTML special characters back their original string characters.
<?php

$html_text = "J&uacute;an and Fel&iacute;pe paid 13&cent; a
piece
for gum."
$translation_table = get_html_translation_table(HTML_ENTITIES);
$flipped = array_flip($translation_table);
print strtr($html_text, $flipped);
// The sentence will now read "Júan and Felípe paid 13¢ a piece
for
// gum" without any HTML translation
?>


• strip_tags() -
                       This function removes all HTML and PHP tags from a string.
<?php
$html_text = "<a href=\"http://www.johnsgifts.com\"><strong>
John's Gifts</strong></a>";
print strip_tags($html_text);
// Returns John's Gifts with no HTML tags
?>


In the even that a tag type should remain while all others are removed, that can be accomplished by
adding the HTML tag in the optional second component of the function.


<?php
$html_text = "<a href=\"http://www.johnsgifts.com\"><strong>
John's Gifts</strong></a>";
print strip_tags($html_text, "<strong>");
// Returns <strong>John's Gifts</strong> but without the <a>
tags
?>

SQL Joins

1. Login in to the mysql client using the login name and password provided by your instructor (if not already logged in). 2. View the existing databases that the MySQL Server is maintaining. SHOW DATABASES; 3. Utilize the photo_album database. USE photo_album; ---- If Need be, recreate the database and load the SQL data in that will be used for this lab CREATE DATABASE photo_album; SOURCE /tmp/photo_album.sql; 4. Query the database to display the active primary customer (email, first and last name) and all the associated active login names associated with that customer. SELECT customers.email_customer, customers.fname, customers.lname, logins.login_name  FROM customers, logins WHERE customers.email_customer = logins.email_customer  AND customers.active_customer = 'True'  AND logins.active_login = 'True';

Self Joins

A table name is always ambiguous when table is joined to itself using a self-join. For example, the Country table in the world database contains an IndepYear column indicating the year in which each country achieved independence. To find all countries that have the same year of independence as some given country, a self-join can be used. However, the query cannot be written like this: mysql> SELECT IndepYear, Name, Name -> FROM Country JOIN Country -> ON IndepYear = IndepYear AND Name = 'Qatar'; ERROR 1066 (42000): Not unique table/alias: 'Country' Furthermore, the ambiguity cannot be removed from column references by preceding them with table name qualifiers because the names remain identical: mysql> SELECT Country.IndepYear, Country.Name, Country.Name -> FROM Country JOIN Country -> ON Country.IndepYear = Country.IndepYear -> AND Country.Name = 'Qatar'; ERROR 1066 (42000): Not unique table/alias: 'Country' It ...
