在PHP中显示数组值

Question

So, I'm working with PHP for the first time and I am trying to retrieve and display the values of an array. After a lot of googling, the only methods I can find for this are print_r , var_dump or var_export . However, all of these methods return something that looks like this:

[a] => apple
[b] => banana
[c] => orange

I can't figure out how to style this outout. I need to strip away the [a] => part and add commas. I know this must be a pretty straightforward process but I haven't been able to track down any documentation that demonstrates how to do it.

Answer 1

There is foreach loop in php. You have to traverse the array.

foreach($array as $key => $value)
{
  echo $key." has the value". $value;
}

If you simply want to add commas between values, consider using implode

$string=implode(",",$array);
echo $string;

Answer 2

<?php $data = array('a'=>'apple','b'=>'banana','c'=>'orange');?>
<pre><?php print_r($data); ?></pre>

Result:
Array
(
[a] => apple
[b] => banana
[c] => orange
)

Answer 3

You can use implode to return your array with a string separator.

$withComma = implode(",", $array);

echo $withComma;
// Will display apple,banana,orange

Answer 4

use implode(',', $array); for output as apple,banana,orange

Or

foreach($array as $key => $value)
{
   echo $key." is ". $value;
}

Answer 5

a simple code snippet that i prepared, hope it will be usefull for you;

$ages = array("Kerem"=>"35","Ahmet"=>"65","Talip"=>"62","Kamil"=>"60");

reset($ages);

for ($i=0; $i < count($ages); $i++){
echo "Key : " . key($ages) . " Value : " . current($ages) . "<br>";
next($ages);
}
reset($ages);

Answer 6

Iterate over the array and do whatever you want with the individual values.

foreach ($array as $key => $value) {
    echo $key . ' contains ' . $value . '<br/>';
}

Answer 7

you can easily use join()

$fruits = array("apple", "banana", "orange");
print join(" ".$fruits);

Answer 8

the join() function must work for you:

$array = array('apple','banana','ananas');
$string = join(',', $array);
echo $string;

Output :

apple,banana,ananas

Answer 9

Other option:

$lijst=array(6,4,7,2,1,8,9,5,0,3);
for($i=0;$i<10;$i++){
echo $lijst[$i];
echo "<br>";
}
