get array from an array of array using value

Question

I have an array of array like this

$data=array(
      array("9900","1","7"),
      array("9901","1","7"),
      array("9902","1","7"),
      array("9903","1","4"),
      array("9904","3","8"),
      array("9908","1","5")
);

I have value 9908 . When I search 9908 then the value array("9908","1","5") should be printed. I have used array_search() but I have not got any success

How I can print the array after finding the value

Answer 1

Try this:

var_dump($data[array_search("9908", array_column($data, 0))]);

To expand it,

array_column returns the values from a single column of the input, identified by the column_key. Optionally, an index_key may be provided to index the values in the returned array by the values from the index_key column of the input array.

---

array_search Searches the array for a given value and returns the first corresponding key if successful.

Edit:

To add some control over it:

$index = array_search("9908", array_column($data, 0));
if($index !== false){
    // do your stuff with $data[$index];
    var_dump($data[$index]);
}

Dumps:

array(3) {
  [0]=>
  string(4) "9908"
  [1]=>
  string(1) "1"
  [2]=>
  string(1) "5"
}

Answer 2

Perhaps this can help:

<?php
function search_first_row($needle, $haystack){
  $data = $haystack;
  $desired_value = $needle;
  foreach($data as $row){
    if($row[0] == $desired_value){
        return $row;
    }
  }
}

 $data=array(
    array("9900","1","7"),
    array("9901","1","7"),
    array("9902","1","7"),
    array("9903","1","4"),
    array("9904","3","8"),
    array("9908","1","5")
);
$searchValue = '9908';

for($i=0; $i<count($data); $i++){
    $innerArray = $data[$i];

    for($j=0; $j<count($innerArray); $j++){
        if($innerArray[$j] == $searchValue){
            print_r($innerArray);
        }
    }
}

try this :

    $data=array(
      array("9900","1","7"),
      array("9901","1","7"),
      array("9902","1","7"),
      array("9903","1","4"),
      array("9904","3","8"),
      array("9908","1","5")
);
foreach ($data as $key => $value) {

    if( in_array("9908",$value)){
        $findindex = $key;
}
}
var_dump($data[$findindex]);
