More intval wierdness (tested with PHP 5.2.3 and 4.3.10).
<?php
$tmp_array = "123,232,141";
if (intval($tmp_array) == $tmp_array)
{
echo "'".intval($tmp_array)."' equals '$tmp_array'\n";
}
else
{
echo "'".intval($tmp_array)."' does not equal
'$tmp_array'\n";
}
?>
Output:
'123' equals '123,232,141'
Odd. Not what was expected. Maybe if I put it into a temporary variable it will normalize itself.
<?php
$tmp_array = "123,232,141";
$tmp = intval($tmp_array);
if ($tmp == $tmp_array)
{
echo "'$tmp' equals '$tmp_array'\n";
}
else
{
echo "'$tmp' does not equal '$tmp_array'\n";
}
?>
Output:
'123' equals '123,232,141'
I don't know if this is a feature, or a bug in PHP (I would certainly classify this as a bug,
but since it is in both PHP 4 and PHP 5 maybe not). If it is a feature, could someone explain it to
me?
