$offset

SaveTo()

SaveTo(string  $path, array  $project = null, string  $encoding = "utf8") : boolean

Save this data collection as csv file

Parameters

string	$path	The csv file path for save this collection object.
array	$project	The csv file header mapping.
string	$encoding	The text file content encoding, by default is utf8 encoding.

Returns

boolean

ToArray()

ToArray() : array

Copies the elements of the ``System.Collections.ArrayList`` to a new System.Object array.

Returns

array —

ContainsKey()

ContainsKey(string  $key) : boolean

Determines whether the System.Collections.Generic.Dictionary<T1,T2> contains the specified key.

判断指定的键名是否存在于当前的字典对象之中

Parameters

string

$key

The key to locate in the System.Collections.Generic.Dictionary<T1,T2>.

Returns

boolean —

true if the System.Collections.Generic.Dictionary<T1,T2> contains an element with the specified key; otherwise, false.
