column_key- The column of values to return. This value may be an integer key of the column you wish to retrieve, or it may be a string key name for an associative array or property name. It may also be
NULLto return complete arrays or objects (this is useful together withindex_keyto reindex the array). index_key- The column to use as the index/keys for the returned array. This value may be the integer key of the column, or it may be the string key name.
Return Values ¶
Returns an array of values representing a single column from the input array.
Changelog ¶
| Version | Description |
|---|---|
| 7.0.0 | Added the ability for the input parameter to be an array of objects. |

Array comparison
array_diff_assoc
Compares array1 against array2 and returns the difference. Unlike array_diff() the array keys are also used in the comparison.
array_diff_key
Compares the keys from array1 against the keys from array2 and returns the difference. This function is like array_diff() except the comparison is done on the keys instead of the values.
array_diff
Compares array1 against one or more other arrays and returns the values in array1 that are not present in any of the other arrays.
array_diff_ukey
Compares the keys from array1 against the keys from array2 and returns the difference. This function is like array_diff() except the comparison is done on the keys instead of the values.
