PHP Array Types:

In PHP an array is more than just array, it is an ordered map. A map is a type that we can associate values to keys. We can consider it as an array, list or vector, hash table, etc. 

In associative array a key may be a string or an integer, for example "5" will be considered as 5 where "05" will be considered as "05". Float in key will be truncated as integer.

Following examples will help you to learn array quickly and effectively.

PHP Array Example:

<?php

$array=array("Hello","New","World");

echo count($array);

sort($array);

for($i=0;$i<=4;$i++){

echo $array[$i]."<br/>";

}

$array=array("Hello","Hi","Hei");

sort($array);

for($i=0;$i<=4;$i++){

echo $array[$i]."<br/>";

}

$array=array("Hello"=>1,"Hi"=>2,"Hei"=>3);

asort($array);

foreach($array as $key=>$value){

echo "Key: ".$key."Value: ".$value."<br/>";

}

echo "<br/>";

$array=array("Hello"=>1,"Hi"=>2,"Hei"=>3);

ksort($array);

foreach($array as $key=>$value){

echo "Key: ".$key."Value: ".$value."<br/>";

}

?>
