Just found out some strange (at least to me) bahavior of echo when it is used with nested arrays.
PHP5 with Apache2 for Win32 I use (wow, it's as if Yoda said that :) )
Here's the example:
<?php
// the array in question:
$blah[0] = array(7, 5, 3, 1);
// echo 'string'.$blah[0][2]; works fine:
echo 'This is blah[0] - '.$blah[0]."<br />\n";
echo 'this is blah[0][2] - '.$blah[0][2];
?>
Output is:
This is blah[0] - Array; this is blah[0][2] - 3
So far so good. However, when you echo it like this you get to the interesting part:
<?php
// echo "string $blah[0][2]"; doesn't recognize the nested array.
echo "This is blah[0] - $blah[0]; ";
echo "this is blah[0][2] - $blah[0][2]";
?>
Output:
This is blah[0] - Array; this is blah[0][2] - Array[2]
Here the 'Array[2]' part is what bothers me. I had a script I coudn't get working
right for a while, and this seems to have been the problem. The '[2]' at the end is
obviously interpreted as part of the string that includes the variable name.
Hope that's of some help to somebody.
Cheers,
Emil Nachev
