How to capture the result of var_dump to a string in PHP?
The resultant value of var_dumo can be extracted to a string using ‘output buffering’. Below is an example demonstrating the same −
Example
<?php
function varDumpToString($var) {
ob_start();
var_dump($var);
$result = ob_get_clean();
return $result;
}
//usage
$data = array('first', 'second', 'third');
$result = varDumpToString($data);
echo $result;The output control function helps in obtaining the output of a function and saving it to a string variable. In general, the output of a PHP code is usually displayed on a browser.
Output
This will produce the following output −
array(3) { [0]=> string(5) "first" [1]=> string(6) "second" [2]=> string(5) "third" }
