search in muti-array

[jeeva]

hi there,

 

I have a array like

$arr[0]=array("name"=>"jeeva","gender"=>"M","age"=>"26");
$arr[1]=array("name"=>"mercy","gender"=>"F","age"=>"16");
$arr[2]=array("name"=>"priya","gender"=>"F","age"=>"46");

and i need to search within the array and get the matching record like,

i will search like below

$name="jeeva";
$gend="M";

And it should give result like

 

$arr[0]=array("name"=>"jeeva","gender"=>"M","age"=>"26");

 

 

Could you please give me a solution?

You could use a foreach to go through each one and ask if the name and gender are the same as what you are searching for. Is this a serious question? If you need to make a more efficient search then you should ensure that the array is first sorted in some manner and then modify one of the existing search types to do what you need.

Something like this:

foreach($array as $key=>$sub_array){
if(in_array($name,$sub_array) && in_array($gend,$sub_array))
{$result=$array[$key];break;}
}
echo "<pre>";
print_r($result);

This data most presumable comes from a database, add a WHERE clause to find your record.

jeeva,

 

This works:

 

<?php

Header("Cache-control: private, no-cache");
Header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
Header("Pragma: no-cache");

$arr      = array();
$matchOut = array();
$match    = array('jeeva', 'M');

$arr[0]=array("name"=>"jeeva","gender"=>"M","age"=>"26");
$arr[1]=array("name"=>"mercy","gender"=>"F","age"=>"16");
$arr[2]=array("name"=>"priya","gender"=>"F","age"=>"46");
$arr[3]=array("name"=>"jeeva","gender"=>"M","age"=>"26");

foreach ($arr as $IDX1 => $outCandidate) {

	$result = findMatch($outCandidate, $match);

	if ($result) {

		$matchOut[$IDX1] = $result;
	}

}

$tempOutput = NULL;
$lineOut    = array();

if (!empty($matchOut)) {

	foreach ($matchOut as $IDX2 => $matchCandidate) {

		$output = NULL;

		foreach($matchCandidate as $itemOut) {

			foreach ($itemOut as $lineOutCandidate) {
				$output .= $lineOutCandidate . ', ';
			}

			$strLen = strlen($output);

			$last   = $strLen - 2; // Get rid of trailing ', '...

			$lineOut[$IDX2] = '$arr[' . $IDX2 . ']' . ' : ' . substr($output,0,$last) . '<br /><br />';

			$thisLine = $lineOut[$IDX2];

		}

	}

	$matchString = NULL;

	foreach ($match as $IDX3 => $inputParm) {

		$whichArrayItem = '$arr[' . $IDX1 .']';

		$matchString .= $inputParm . ', ';

	}

	$strlen = strlen($matchString);

	$last = $strlen - 2; // Get rid of trailing ', '

	$matchString = substr($matchString,0,$last);

	echo "Match Found for : '" . $matchString . "' in : <br /><br /><ul> \n";

	foreach($lineOut as $echoCandidate) {
		echo $echoCandidate;
	}

}
else {
	echo 'No Matches Found...';
}

function findMatch($outCandidate,$match) {

	$matchName   = $match[0];
	$matchGender = $match[1];
	$matchFound  = array();

	if ( (in_array($matchName, $outCandidate)) && (in_array($matchGender, $outCandidate))) {
		$matchFound[] = $outCandidate;
	}

	if (!empty($matchFound)) {

	}
	else {

	}
