What is the best way to accomplish this?

Actually, this can be done. Through a php extension.
File: config.m4
PHP_ARG_ENABLE(test, whether to enable test Extension support, [ --enable-test Enable test ext support]) if test "$PHP_TEST" = "yes"; then AC_DEFINE(HAVE_TEST, 1, [Enable TEST Extension]) PHP_NEW_EXTENSION(test, test.c, $ext_shared) fi
File: php_test.h
#ifndef PHP_TEST_H #define PHP_TEST_H 1 #define PHP_TEST_EXT_VERSION "1.0" #define PHP_TEST_EXT_EXTNAME "test" PHP_FUNCTION(getaddress4); PHP_FUNCTION(getaddress); extern zend_module_entry test_module_entry; #define phpext_test_ptr &test_module_entry #endif
File: test.c
#ifdef HAVE_CONFIG_H #include "config.h" #endif #include "php.h" #include "php_test.h" ZEND_BEGIN_ARG_INFO_EX(func_args, 1, 0, 0) ZEND_END_ARG_INFO() static function_entry test_functions[] = { PHP_FE(getaddress4, func_args) PHP_FE(getaddress, func_args) {NULL, NULL, NULL} }; zend_module_entry test_module_entry = { #if ZEND_MODULE_API_NO >= 20010901 STANDARD_MODULE_HEADER, #endif PHP_TEST_EXT_EXTNAME, test_functions, NULL, NULL, NULL, NULL, NULL, #if ZEND_MODULE_API_NO >= 20010901 PHP_TEST_EXT_VERSION, #endif STANDARD_MODULE_PROPERTIES }; #ifdef COMPILE_DL_TEST ZEND_GET_MODULE(test) #endif PHP_FUNCTION(getaddress4) { zval *var1; zval *var2; zval *var3; zval *var4; char r[500]; if( zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "aaaa", &var1, &var2, &var3, &var4) == FAILURE ) { RETURN_NULL(); } sprintf(r, "n%p - %p - %p - %pn%p - %p - %p - %p", var1, var2, var3, var4, Z_ARRVAL_P(var1), Z_ARRVAL_P(var2), Z_ARRVAL_P(var3), Z_ARRVAL_P(var4) ); RETURN_STRING(r, 1); } PHP_FUNCTION(getaddress) { zval *var; char r[100]; if( zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "a", &var) == FAILURE ) { RETURN_NULL(); } sprintf(r, "%p", Z_ARRVAL_P(var)); RETURN_STRING(r, 1); }
Then all you have to do is phpize it, config it, and make it. Add a "extension=/path/to/so/file/modules/test.so" to your php.ini file. And finally, restart the web server, just in case.
<?php $x = array("123"=>"123"); $w = $x; $y = $x; $z = &$x; var_dump(getaddress4($w,$x,$y,$z)); var_dump(getaddress($w)); var_dump(getaddress($x)); var_dump(getaddress($y)); var_dump(getaddress($z)); ?>
Returns(at least for me, your memory addresses will probably be different)
string ' 0x9efeb0 - 0x9effe0 - 0x9ef8c0 - 0x9efeb0 0x9efee0 - 0x9f0010 - 0x9ed790 - 0x9efee0' (length=84) string '0x9efee0' (length=8) string '0x9f0010' (length=8) string '0x9ed790' (length=8) string '0x9efee0' (length=8)
Thanks to Artefacto for pointing this out, but my original code was passing the arrays by value, so thereby was recreating arrays including the referenced-one, and giving you bad memory values. I have since changed the code to force all params to be passed by reference. This will allow references, arrays, and object, to be passed in unmolested by the php engine. $w/$z are the same thing, but $w/$x/$y are not. The old code, actually showed the reference breakage and the fact that the memory addresses would change or match when all variables were passed in vs multiple calls to the same function. This was because PHP would reuse the same memory when doing multiple calls. Comparing the results of the original function would be useless. The new code should fix this problem.
FYI - I'm using php 5.3.2.
You can try below code to merge array. Code generates desired output required to you. I have used sample array as given by you:
<?php
$arr1=array(
"384"=>array("name"=>"SomeMovieName1","age"=>"12.2 hrs","IMDBLink"=>"","IMDBRating"=>"", "coverArt"=>""),
"452"=>array("name"=>"SomeMovieName2","age"=>"15.2 hrs","IMDBLink"=>"","IMDBRating"=>"", "coverArt"=>""),
"954"=>array("name"=>"SomeMovieName3","age"=>"4.2 hrs","IMDBLink"=>"","IMDBRating"=>"", "coverArt"=>"")
);
$arr2=array(
"384" => array("IMDBLink" => "7.2", "IMDBRating" => "http://www.imdb.com/LinkToMovie1", "coverArt" => "http://www.SomeLinkToCoverArt.com/1"),
"452" => array("IMDBLink" => "5","IMDBRating" => "http://www.imdb.com/LinkToMovie2", "coverArt" => "http://www.SomeLinkToCoverArt.com/2"),
"954"=>array("IMDBLink" => "8","IMDBRating" => "http://www.imdb.com/LinkToMovie3", "coverArt" => "http://www.SomeLinkToCoverArt.com/3")
);
$arr3 = array();
foreach($arr1 as $key=>$val)
{
$arr3[] = array_merge($val, $arr2[$key]);
}
echo "<pre>";
print_r($arr3);
?>
You can use array_slice
or array_splice
:
$b = array_slice($a, 0, 10);
$c = array_splice($a, 0, 10);
Note that array_slice
copies the items of $a
and returns them while array_splice
does modify $a
itself and only returns the items that have been removed from $a
.
The problem with your code that you create pairs with color constants which are Int
s (allColours
has type Array<Pair<Int, Int>>)
, but you expect Array<Pair<Color, Color>>
. What you have to do is change type pegColours
type and use take
:
var pegColours: Array<Pair<Int, Int>> = allColours.take(3).toTypedArray()
Also you have to call toTypedArray()
cause Array.take
returns List
rather than Array
. Or you can change pegColours
type as following:
var pegColours: List<Pair<Int, Int>> = allColours.take(3)
Use array_slice()
This is an example from the PHP manual: array_slice
There is only a small issue
If the array indices are meaningful to you, remember that
array_slice
will reset and reorder the numeric array indices. You need thepreserve_keys
flag set totrue
to avoid this. (4th parameter, available since 5.0.2).Example:
Output:
