A year has not come, by example scattered
As usual, two for personal use of "small" things, to point to improve the opinion of more points, pure access to the inspection manager should be deleted paste, hey
Note: Because it is for personal use, the incoming basic is formal format, so did not do fault tolerance, this user self-
Searches for a string in a file, returning the line number of the row
$lines =new arrayiterator (file (filename));
$regex = regular for searching; Must be regular because the following iterator is a regular iterator
$regexFilter = new Regexiterator ($lines, $regex, Regexiterator::get_match);
$items = Iterator_to_array ($regexFilter);
In fact, this part of the above can be more widely used, the use of large files to deal with a lot of help, go to extrapolate yourself
$keys = Array_keys ($items); If the value you are searching for is not unique, here is an array of multiple line numbers (note that the first line is "0")
$lineNumber = $keys [0]; If the value you are searching for is unique, here is the line number you want
Array-to-row (matrix) arrays Exchange one-and two-dimensional keys
What is a matrix array, each key name exists and the order is the corresponding two-dimensional array, a simple example is SQL after the two-dimensional array, of course, there are more
Note is the order corresponds, otherwise there is no meaning, two-dimensional is the number of key names can also be used, but the number of key names feel is not very significant, because the number of key names with orthogonal poor very convenient
Class Squarearray
{
Public Function Swaprowcol ($array)
{
$mit = new Multipleiterator (MULTIPLEITERATOR::MIT_KEYS_ASSOC);
foreach ($array as $key = + $value) {$temArr = new arrayiterator ($value); $mit->attachiterator ($TEMARR, $key);}
$arr = Array ();
foreach ($mit as $item) Array_push ($arr, $item); Here originally want to direct Iterator_to_array province circulation, but error, puzzled
if (isset ($array [0])) $arr = Array_combine (Array_keys ($array [0]), $arr);
return $arr;
}
}
Only one Exchange method is written in the class, and interested people can extend their own
SPL code is very concise, but too few documents, many of them have to write their own test to see the results, tired AH
