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" }
