Echoing or Printing Arrays in PHP
When working with arrays in PHP, it's often necessary to display their contents. However, simply using echo $array will result in the entire array structure being displayed. To echo or print the contents of the array without the structure, various methods are available.
One option is to use the print_r() function. For instance, if you have an array like the one provided, you can use:
print_r($results);
This will output the contents of the array, but it will include the key-value pairs.
To display the contents in a more readable format, you can use the HTML
tag:</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">echo '<pre class="brush:php;toolbar:false">'; print_r($results); echo '';
Another method is to use var_dump():
var_dump($results);
var_dump() provides more detailed information about the array, including its type and length.
For specific element access and manipulation, you can use foreach():
foreach ($results as $result) {
echo $result['type'];
echo "<br>";
}This will iterate over each element in the $results array and print out the type value.
