For some specific purposes you may want to know the current key of your array without going on a loop. In this case you could do the following:
reset($array);
echo key($array) . ' = ' . current($array);
The following functions are not very well known but can be pretty useful in very specific cases:
key($array); //Returns current key
reset($array); //Moves array pointer to first record
current($array); //Returns current value
next($array); //Moves array pointer to next record and returns its value
prev($array); //Moves array pointer to previous record and returns its value
end($array); //Moves array pointer to last record and returns its value
OTHER EXAMPLE :
<?php foreach($array as $text => $url): ?>
<a href="<?php echo $url; ?>"><?php echo $text; ?></a>
<?php endforeach; ?>
$array = array(
'SOA' => 'http://soatechnology.net',
'Delhijurix' => 'http://delhijurix.com'
);
foreach($array as $title => $url){
echo '<a href="' . $url . '">' . $title . '</a>';
}
