Extract a row by value from php array - php

Question

This is my array:
Array (
[0] => Array ( [SocketID] => 1 [SocketName] => Name [SocketDecimal] => 0 [SocketHex] => 00 [SocketAtt] => 1 [Category] => 1 [Value] => 100 [Procentage] => 0 )
[1] => Array ( [SocketID] => 2 [SocketName] => Name2 [SocketDecimal] => 50 [SocketHex] => 32 [SocketAtt] => 1 [Category] => 1 [Value] => 800 [Procentage] => 0 )
[2] => Array ( [SocketID] => 3 [SocketName] => Name3 [SocketDecimal] => 100 [SocketHex] => 64 [SocketAtt] => 1 [Category] => 1 [Value] => 60 [Procentage] => 0 )
)
How can I extract a row by SocketDecimal?
For example: I want to extract row where SocketDecimal = 50 and make new an array only with that row.

Answer 1

foreach($array as $entry) {
if($entry['SocketDecimal'] == 50)
$newArr[] = $entry;
}
$newArr will contain the desired "row". Of course you can manipulate the if-statement depending on which "row" (I'd just call it array entry) you want to extract.

Answer 2

It's not the best way for big data! It's easy for deep multiarrays.
$arr = array(
array('socket_id'=>1,'name'=>'test1'),
array('socket_id'=>2,'name'=>'test2'),
array('socket_id'=>3,'name'=>'test3'),
array('socket_id'=>2,'name'=>'test4')
);
$newArr = array();
foreach($arr as $row){
foreach($row as $key=>$r){
if($key == 'socket_id' && $r==2)
$newArr[] = $row;
}
}
print_r($newArr);

Answer 3

$result = array();
foreach($input as $i){
if($i['SocketDecimal']==50)
$result[]=$i;
}

Answer 4

You can do it by this method
foreach ($yourarray as $key => $value){
$newarray = array("SocketDecimal"=>$value["SocketDecimal"];
}
print_r($newarray);

Answer 5

If your result array is like given below
$arr = array(
array( 'SocketID' => 1, 'SocketName' => 'Name', 'SocketDecimal' => 0, 'SocketHex' => 0, 'SocketAtt' => 1, 'Category' => 1, 'Value' => 100, 'Procentage' => 0 ),
array ( 'SocketID' => 2, 'SocketName' => 'Name2', 'SocketDecimal' => 50, 'SocketHex' => 32, 'SocketAtt' => 1, 'Category' => 1, 'Value' => 800, 'Procentage' => 0 ),
array ( 'SocketID' => 3, 'SocketName' => 'Name3', 'SocketDecimal' => 100, 'SocketHex' => 64, 'SocketAtt' => 1, 'Category' => 1, 'Value' => 60, 'Procentage' => 0 )
);
print_r($arr);
Get row for SocketDecimal=50 by following loop:
<pre>
$resultArr = '';
foreach($arr as $recordSet)
{
if($recordSet['SocketDecimal'] == 50)
{
$resultArr[] = $recordSet;
break;
}
}
</pre>
print_r($resultArr);
break foreach loop so that it will not traverse for all the array when SocketDecimal(50) founded.

Answer 6

You can use array_column + array_search combo
$array = Array (
"0" => Array ( "SocketID" => 1, "SocketName" => "Name", "SocketDecimal" => 0, "SocketHex" => 00, "SocketAtt" => 1, "Category" => 1, "Value" => 100, "Procentage" => 0 ) ,
"1" => Array ( "SocketID" => 2, "SocketName" => "Name2", "SocketDecimal" => 50, "SocketHex" => 32, "SocketAtt" => 1, "Category" => 1, "Value" => 800, "Procentage" => 0 ),
"2" => Array ( "SocketID" => 3, "SocketName" => "Name3", "SocketDecimal" => 100, "SocketHex" => 64, "SocketAtt" => 1, "Category" => 1, "Value" => 60 ,"Procentage" => 0 )
);
var_dump($array[array_search(50,array_column($array,'SocketDecimal'))]);
