Methods

diff()

Returns the diff between two arrays or strings as string.

public diff(array<string|int, mixed>|string $from, array<string|int, mixed>|string $to[, null|LongestCommonSubsequenceCalculator $lcs = null ]) : string
Parameters
$from : array<string|int, mixed>|string
$to : array<string|int, mixed>|string
$lcs : null|LongestCommonSubsequenceCalculator = null
Return values
string —

diffToArray()

Returns the diff between two arrays or strings as array.

public diffToArray(array<string|int, mixed>|string $from, array<string|int, mixed>|string $to[, LongestCommonSubsequenceCalculator $lcs = null ]) : array<string|int, mixed>

Each array element contains two elements:

  • [0] => mixed $token

  • [1] => 2|1|0

  • 2: REMOVED: $token was removed from $from

  • 1: ADDED: $token was added to $from

  • 0: OLD: $token is not changed in $to

Parameters
$from : array<string|int, mixed>|string
$to : array<string|int, mixed>|string
$lcs : LongestCommonSubsequenceCalculator = null
Return values
array<string|int, mixed> —
