将日期数字字符串转换为Day of PHP

Question

I have a PHP script outputting dates like this 2014-08-06 and i wish to make them output as Wednesday 6th August 2014 instead.

I am already using the number previously so i need to take this from the variable of which holds the number string and convert that.

The PHP

function dateRange($start, $end) {
    date_default_timezone_set('UTC');

    $diff = strtotime($end) - strtotime($start);

    $daysBetween = floor($diff/(60*60*24));

    $formattedDates = array();
    for ($i = 0; $i <= $daysBetween; $i++) {
        $tmpDate = date('Y-m-d', strtotime($start . " + $i days"));
        $formattedDates[] = date('Y-m-d', strtotime($tmpDate));
    }    
    return $formattedDates;
}


$start=$date_system_installed;
$end=$today;

$formattedDates = dateRange($start, $end);

    foreach ($formattedDates as $dt)
{
 echo $dt; //this is where i wish to change the number to the word/s. 
}

You can use DateTime::createFromFormat and DateTime::format to create a DateTime object and then create a string in the format you want:

echo DateTime::createFromFormat('Y-m-d', $dt)->format('l jS F Y');

Ideally what I would do is work with DateTime object all the way through:

function dateRange($start, $end) {
    date_default_timezone_set('UTC');
    $daysBetween = $start->diff($end)->format('%R%a');
    $formattedDates = array();
    for ($i = 0; $i <= $daysBetween; $i++) {
        $formattedDates[] = clone $start->modify('+1 day');
    }    
    return $formattedDates;
}

$start = DateTime::createFromFormat('Y-m-d', "2014-08-01");
$end = new DateTime;
$formattedDates = dateRange($start, $end);
foreach ($formattedDates as $dt)
{
    echo $dt->format('l jS F Y');
}

You can use function date http://php.net//manual/en/function.date.php

For example:

<?php

    $date = strtotime('2014-08-06');
    echo date('l jS F Y', $date);  //Wednesday 6th August 2014
    /*
        l - full name of week day, jS - day of month with suffix,
        F - full name of month, Y - year
    */
