Use of + with arrays

[Bob Stearns]

In a note on 31-Jul-2002 added to the unshift function the writer
stated that array2=arrray1+ array2 was equivalent to
unshift(arrayw, list(array1)). My php seems to take strong objection to
this [Fatal error: Unsupported operand types in
/var/www/html/GEM/etFlush/embryo_newFroze n.php on line 417]. Am I doing
something wrong? Was the original poster on something? Is this a version
problem?

Works for me. Post a minimal test script.

Don't know, can't see your code.

Works for me on 5.0.4.

Don't know, what's your version?

The following code produces that error:

<?php
$arrayone = array("newkey"= >"newvalue") + $arrayone;
var_dump($array one);
?>

... because $arrayone is not defined and so isn't an array.

The following works as required:

<?php
$arrayone = array();
$arrayone = array("newkey"= >"newvalue") + $arrayone;
var_dump($array one);
?>
