How to echo or print an array in PHP?

I have this array

Array
(
  [data] => Array
    (
      [0] => Array
        (
          [page_id] => 204725966262837
          [type] => WEBSITE
        )

      [1] => Array
        (
          [page_id] => 163703342377960
          [type] => COMMUNITY
        )
      )
)

My question is how can I just echo the content without this structure? I tried

foreach ($results as $result) {
    echo $result->type; 
    echo "<br>";
}

This will do

foreach($results['data'] as $result) {
    echo $result['type'], '<br>';
}

To see the contents of array you can use.

1) print_r($array); or if you want nicely formatted array then:

echo '<pre>'; print_r($array); echo '</pre>';

2) use var_dump($array) to get more information of the content in the array like datatype and length.

  • 1Nice and elegant. You might want to change the closing tag in #1 from <pre/> to </pre>. – Michael Jun 21 '14 at 21:47

  • 1This answer does not address the mistake that OP did. – Shiplu Mokaddim Nov 21 '14 at 17:28

  • 2could you explain how the <pre></pre> construct makes this display "nicely?" – Robin Andrews May 28 '16 at 17:04

  • 1@Robin <pre> tag displays new lines and tabulation as it's outputed by print_r(); without <pre> you would see a messy unformatted bounds of data. To see it formatted you should then view the html page source. – j.c Sep 29 '16 at 9:00

If you just want to know the content without a format (e.g. for debuging purpose) I use this:

echo json_encode($anArray);
  • I wanted to extract some data from a html - php document using Cordova InAppBrowser executeScript method, without json_encode($array) I could not achieve that! Thanks a lot @Mark E – Hamid Araghi Mar 29 '19 at 11:42

There are multiple function to printing array content that each has features.

Prints human-readable information about a variable.

$arr = ["a", "b", "c"];
echo "<pre>";
print_r($arr);
echo "</pre>";
Array
(
    [0] => a
    [1] => b
    [2] => c
)

Displays structured information about expressions that includes its type and value.

echo "<pre>";
var_dump($arr);
echo "</pre>";
array(3) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
}

Displays structured information about the given variable that returned representation is valid PHP code.

echo "<pre>";
var_export($arr);
echo "</pre>";
array (
  0 => 'a',
  1 => 'b',
  2 => 'c',
)

Note that because browser condense multiple whitespace characters (including newlines) to a single space (answer) you need to wrap above functions in <pre></pre> to display result in correct format.

Also there is another way to printing array content with certain conditions.

Output one or more strings. So if you want to print array content using echo, you need to loop through array and in loop use echo to printing array items.

foreach ($arr as $key=>$item){
    echo "$key => $item <br>";
}
0 => a 
1 => b 
2 => c 

You can use print_r, var_dump and var_export funcations of php:

print_r: Convert into human readble form

<?php
echo "<pre>";
 print_r($results); 
echo "</pre>";
?>

var_dump(): will show you the type of the thing as well as what's in it.

var_dump($results);

foreach loop: using for each loop you can iterate each and every value of an array.

foreach($results['data'] as $result) {
    echo $result['type'].'<br>';
}
foreach($results['data'] as $result) {
    echo $result['type'], '<br />';
}

You have no need to put for loop to see the data into the array, you can simply do in following manner

<?php
echo "<pre>";
 print_r($results); 
echo "</pre>";
?>

I know this is an old question but if you want a parseable PHP representation you could use:

$parseablePhpCode = var_export($yourVariable,true);

If you echo the exported code to a file.php (with a return statement) you may require it as

$yourVariable = require('file.php');

I checked the answer however, (for each) in PHP is deprecated and no longer work with the latest php versions.

Usually we would convert an array into a string to log it somewhere, perhaps debugging or test etc.

I would convert the array into a string by doing:

$Output = implied (",",$SourceArray);

Whereas:

$output is the result (where the string would be generated

",": is the separator (between each array field

$SourceArray: is your source array.

Loop through and print all the values of an associative array, you could use a foreach loop, like this:

foreach($results as $x => $value) {
    echo $value;
}
