虽然循环没有显示？

I am trying to write out all the array values using a while loop but it isn't working, any tips?

$console = array("Wii","Playstation 3","Xbox","Dator");
echo "I like " .$console[0] . " and " . $console[1] . ".";

while($console <5){
    echo "The console you like is: $console <br>";
    $x++;
}

My first echo is visible but the second one in my loop is not, what have I done wrong? The while loop should be able to show all 4 consoles variables but it doesn't show anything.

You can get your desired output by using foreach() and no need to use any extra function like count()

Example:

$console = array("Wii","Playstation 3","Xbox","Dator");
foreach ($console as $key => $value) {
    echo $value."<br/>"; 
}

Result:

Wii
Playstation 3
Xbox
Dator

Also note that, while($console <5){ this condition will make your loop to infinite, if you still want to use while() loop than you can check other answer or you can follow this example also.

From the Manual:

<?php
$console = array("Wii","Playstation 3","Xbox","Dator");
while (list ($key, $val) = each ($console) ) 
    echo $val."<br/>"; 
?>

Result:

Wii
Playstation 3
Xbox
Dator

You can also explore the manual: http://php.net/manual/en/control-structures.while.php

For the loop to be dynamic, you need to count() the amount of items in the array and the use a counter variable ($x in this instance) to output each iteration of the array.

<?php 

$console = array("Wii","Playstation 3","Xbox","Dator");
echo "I like " .$console[0] . " and " . $console[1] . ".";

$x=0;

while($x < count($console)){
echo "The console you like is: ". $console[$x] ."<br>";
$x++;
}


?>

As you need to write / show all the values from the array using the while loop, you need the total number of count values and a counter. The counter track the array pointer and inside the while loop you need to increment it.

$console = array("Wii","Playstation 3","Xbox","Dator");
//echo "I like " .$console[0] . " and " . $console[1] . ".";
$count = count($console);
$counter = 0

while($counter <= $count){
    echo "The console you like is: ". $console[$counter]." <br>";
    $counter++;
}

You can use the foreach(){} while will perform better for this type of array.
