Here's an example of a multidimensional array - I "unset" one
of the values in the middle - I don't know why this won't work
for you:
<?
$arr1 = array("a" => array('1' => "a111",
'2' => "a222",
'3' => "a333"),
"b" => array('1' => "b111",
'2' => "b222",
'3' => "b333"),
"c" => array('1' => "c111",
'2' => "c222",
'3' => "c333"));
foreach ($arr1 as $key1 => $value1) {
echo "<br>";
echo "key=[$key1], value=[$value1]<br>";
foreach ($value1 as $key2 => $value2) {
echo " key2=[$key2], value2=[$value2]<br>";
}
}
unset($arr1["b"]["2"]);
echo "<br><br>Unset b2 now<br><br>";
foreach ($arr1 as $key1 => $value1) {
echo "<br>";
echo "key=[$key1], value=[$value1]<br>";
foreach ($value1 as $key2 => $value2) {
echo " key2=[$key2], value2=[$value2]<br>";
}
}
?>
Here's the output displayed on the browser:
-------------------------------------------
key=[a], value=[Array]
key2=[1], value2=[a111]
key2=[2], value2=[a222]
key2=[3], value2=[a333]
key=[b], value=[Array]
key2=[1], value2=[b111]
key2=[2], value2=[b222]
key2=[3], value2=[b333]
key=[c], value=[Array]
key2=[1], value2=[c111]
key2=[2], value2=[c222]
key2=[3], value2=[c333]
Unset b2 now
key=[a], value=[Array]
key2=[1], value2=[a111]
key2=[2], value2=[a222]
key2=[3], value2=[a333]
key=[b], value=[Array]
key2=[1], value2=[b111]
key2=[3], value2=[b333]
key=[c], value=[Array]
key2=[1], value2=[c111]
key2=[2], value2=[c222]
key2=[3], value2=[c333]
