The var_export function is used to output the value of a variable as executable PHP code. Its syntax is:

var_export($variable, $return = false);

$variable is the variable to be output, and $return is an optional parameter. If set to true, the function will return the output string instead of directly outputting it to the page.

For example, outputting an array as executable PHP code:

$array = array('apple', 'banana', 'orange');
var_export($array);

The output result is:

array (
  0 => 'apple',
  1 => 'banana',
  2 => 'orange',
)
