Re: [PHP] delete an element from an array

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 "brbrUnset b2 nowbrbr";
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]

Have a look at
http://www.php.net/manual/en/function.unset.php
"unset" may do what you want.
