Ask PHP algorithm, two-dimensional array to take out one-dimensional array of the same ID as several new two-dimensional arrays.

PHP two-dimensional array algorithm

Little brother just learned PHP soon, encountered a problem, ask the heroes, thank you!

The two-dimensional array is as follows;
$arr = Array (
Array (' ID ' =>100, ' value ' =>100),
Array (' ID ' =>100, ' value ' =>130,
Array (' ID ' =>100, ' value ' =>140),
Array (' ID ' =>100, ' value ' =>150),
Array (' ID ' =>101, ' value ' =>1600),
Array (' ID ' =>101, ' value ' =>100),
Array (' ID ' =>102, ' value ' =>100),
Array (' ID ' =>102, ' value ' =>100),
Array (' ID ' =>102, ' value ' =>100),
Array (' ID ' =>103, ' value ' =>100),
Array (' ID ' =>103, ' value ' =>100),
Array (' ID ' =>104, ' value ' =>100),
Array (' ID ' =>104, ' value ' =>100),
Array (' ID ' =>104, ' value ' =>100),
Array (' ID ' =>105, ' value ' =>100)
);


How to split into the following 5 two-dimensional arrays:
ARR1 (
Array (' ID ' =>100, ' value ' =>100),
Array (' ID ' =>100, ' value ' =>130,
Array (' ID ' =>100, ' value ' =>140),
Array (' ID ' =>100, ' value ' =>150)
);

ARR2 (
Array (' ID ' =>101, ' value ' =>1600),
Array (' ID ' =>101, ' value ' =>100)
);

ARR3 (
Array (' ID ' =>102, ' value ' =>100),
Array (' ID ' =>102, ' value ' =>100),
Array (' ID ' =>102, ' value ' =>100)
);

ARR4 (
Array (' ID ' =>103, ' value ' =>100),
Array (' ID ' =>103, ' value ' =>100)

);

ARR5 (
Array (' ID ' =>104, ' value ' =>100),
Array (' ID ' =>104, ' value ' =>100),
Array (' ID ' =>104, ' value ' =>100),
Array (' ID ' =>105, ' value ' =>100)
);

ARR5 (
Array (' ID ' =>105, ' value ' =>100)
);

Reply to discussion (solution)

ARR5 (
Array (' ID ' =>104, ' value ' =>100),
Array (' ID ' =>104, ' value ' =>100),
Array (' ID ' =>104, ' value ' =>100),
);

ARR6 (
Array (' ID ' =>105, ' value ' =>100)
);

??

Is it 6 arrays or 5 arrays? Two ARR5 the data is not the same?

Really don't understand ~ ~ ~ can you tell me the law? I didn't see the rules of the 6 arrays below you .... In particular, the two arr5 inside of the thing directly to the whole circle of people ...

6, the last ARR5 should be: ARR6

ARR6 (
Array (' ID ' =>105, ' value ' =>100)
);

Sorry, copy error.

Is the same ID to put in a two-dimensional array,
The above array has 6 kinds of id:100,101,102,103,104,105, which are to be put into 6 different two-dimensional arrays respectively.

$arr = array (' ID ' =>100, ' value ' =>100), array (' ID ' =>100, ' value ' =>130), array (' ID ' =>100, ' value ' = >140), array (' ID ' =>100, ' value ' =>150), array (' ID ' =>101, ' value ' =>1600), array (' ID ' =>101, ' value ' = >100), array (' ID ' =>102, ' value ' =>100), array (' ID ' =>102, ' value ' =>100), array (' ID ' =>102, ' value ' = >100), array (' ID ' =>103, ' value ' =>100), array (' ID ' =>103, ' value ' =>100), array (' ID ' =>104, ' value ' = >100), array (' ID ' =>104, ' value ' =>100), array (' ID ' =>104, ' value ' =>100), array (' ID ' =>105, ' value ' = >100)); foreach ($arr as $key + $val) {$newarr [$val [' ID ']][]=array (' id ' = ' + ' $val [' id '], ' value ' = * = $val [' Value ']);} $arr 1= $newarr [' n ']; $arr 2= $newarr [' 101 ']; $arr 3= $newarr [' 102 ']; $arr 4= $newarr [' 103 ']; $arr 5= $newarr [' 104 ']; $arr 6 = $newarr [' 105 '];

$arr = Array (  ' id ' =>100, ' value ' =>100),  array (' ID ' =>100, ' value ' =>130),  array (' id ' = >100, ' value ' =>140),  array (' ID ' =>100, ' value ' =>150),  array (' ID ' =>101, ' value ' =>1600), Array (  ' id ' =>101, ' value ' =>100),  array (' ID ' =>102, ' value ' =>100),  array (' ID ' =>102, ' Value ' =>100 ', array (  ' id ' =>102, ' value ' =>100),  array (' ID ' =>103, ' value ' =>100),  Array ( ' id ' =>103, ' value ' =>100),  array (' ID ' =>104, ' value ' =>100),  array (' ID ' =>104, ' value ' = =  Array (' ID ' =>104, ' value ' =>100),  array (' ID ' =>105, ' value ' =>100)); foreach ($arr as $v) $ res[$v [' id ']][] = $v;//print_r ($res);//You can directly use this array//You can also import the variable table after accessing Extract (Array_values ($res), Extr_prefix_all, ' arr ') ;//such as Print_r ($arr _3);

Thank you very much AHUI_LCM and xuzuning, so simple conversion I did not think out, really ashamed.
Ask the next 2 and you heroes, how can I quickly improve the operation of the PHP array. are always affected by arrays in other languages.
Thank you! Score I'm still going to give the first brother AHUI_LCM to help me. Brother Xuzuning to answer the more perfect point, also very grateful to xuzuning.

The code above//This code is run directly under the $arr = array (' id ' = ' = ', ' value ' = ' + '), array (' id ' = +, ' value ' = '), a Rray (' id ' = +, ' value ' = + +), array (' id ' = ' = ', ' value ' = '), array (' id ' = = 101, ' value ' =&gt ; ), array (' id ' = = 101, ' value ' = +), array (' id ' = = 102, ' value ' = +), array (' id ' = = 102, ' VA Lue ' + + ', array (' id ' = = 102, ' value ' = +), array (' id ' = = 103, ' value ' = +), array (' ID ' =&gt ; 103, ' value ' = +), array (' id ' = = 104, ' value ' = +), array (' id ' = = 104, ' value ' = +), Array (' id ' = = 104, ' value ' = ' + ', array (' id ' = ' = ' value ' = ') '), foreach ($arr as $v) $res [$v [' id ']][] = $v ; My_debug ($res);//You can directly use this array//You can also import the variable table after accessing Extract (Array_values ($res), Extr_prefix_all, ' arr '); My_debug ($arr _0); My_debug ($arr _1); My_debug ($arr _2); My_debug ($arr _3); function my_debug ($v = null, $var _name = null, $ method = ' Dump ', $backtrace = False) {$display _none = ";" if (Defined (' FRONTPAGE ')) {$display _none = "display:none;";} Print (""); $call _stack = Debug_backtrace ();p rintf (' file:%s,%s (), line:%s
