# var_export

(PHP 4 >= 4.2.0)

var_export -- Outputs or returns a string representation of a variable

## Description

mixed var_export ( mixed expression [, bool return])

This function returns structured information about the variable that is passed to this function. It is similar to var_dump() with the exception that the returned representation is valid PHP code.

You can also return the variable representation by using `TRUE` as second parameter to this function.

Compare var_export() to var_dump().

    <pre>
    <?php
    $a = array (1, 2, array ("a", "b", "c"));
    var_export ($a);

    /* output:
    array (
      0 => 1,
      1 => 2,
      2 =>
      array (
        0 => 'a',
        1 => 'b',
        2 => 'c',
      ),
    )
    */

    $b = 3.1;
    $v = var_export($b, TRUE);
    echo $v;

    /* output:
    3.1
    */
    ?>
    </pre>
