Web Scripting (PHP)
,
Write a script that uses at
-
least six string functions. You have to use 3 string functions that is not
discussed in the book (
www.php.net
) and
the other 3 could be from the book. Inside the script,
explain what the function is doing.
Output:
The initial string displays:
It is becoming increasingly clear that we are responsible for warming of the
Earth primarily due to the burning of f
ossil fuels. Predicting the
implications of this or how the picture will change in the future are big
challenges for scientists and today's report by the IPCC, whilst recognising
uncertainties, gives us the best possible insight into what may lay ahead.

It is becoming
increasingly clear that
we are responsible for
warming of the Earth
primarily due to the
burning of fossil fuels.

scientists and today's
report by the IPCC,
whilst recognising
uncertainties, gives us

Purpose: Comprehend and demonstrate the use of String functions
as discussed in class

According to the U.S. Census
Bureau, the 12 largest American cities (by population) in 2005 were as
follows:
(the numbers are not actual numbers)
New Jersey, NJ (9,008,278 people)
Los Angeles, CA (3,694,410)
Chicago, IL (2,985,016)
Houston, TX (1,845,631)
Philadelphia, PA (1,517,550)
Phoenix, AZ (1,321,045)
San Diego, CA (1,283,400)
Dallas, TX (1,188,580)
San Antonio, TX (1,198,646)
Detroit, MI (951,270)
Georgia, GA (378, 457)
New York, NY (678, 4567)
Write a script that d
efine an array (or arrays) that holds this information about loc
ations and population.
Print a table of locations and population information that includes the total population in all 12 cities.
Modify your solution so that the rows in result table are ordered by population.
Then modify your solution so that
the rows are ordered by city name.

Here is your php script to accomplish all three requirements. Let me know via comment if you need further help:

<head><title>PHP Arrays</title></head>
<body>
<?php
function print_table($cities)
{
echo '<table border="2" cellpadding="5"><tr><th>City Name</th><th>State</th><th>Population</th></tr>';
foreach($cities as $obj)
{
echo '<tr>';
echo '<td>' . $obj['name'] . '</td><td>' . $obj['state'] . '</td><td>' . $obj['population'] . '</td>';
echo '</tr>';
}
echo '</table>';
}
$cities = array();
$cities[] = array('name' => 'New Jersey', 'state' => 'NJ', 'population' => 9008278);
$cities[] = array('name' => 'Los Angeles', 'state' => 'CA', 'population' => 3694410);
$cities[] = array('name' => 'Chicago', 'state' => 'IL', 'population' => 2985016);
$cities[] = array('name' => 'Houston', 'state' => 'TX', 'population' => 1845631);

$cities[] = array('name' => 'New York', 'state' => 'NY', 'population' => 6784567);
echo '<h3>Original Data: </h3>';
print_table($cities);
# Calculate Total:
$total = 0;
foreach($cities as $obj)

}
array_multisort($city_name, SORT_ASC, $cities);
print_table($cities);
