Search Results from an array by search the keyword in php

Question

I have an array like

Array ( 
    [4621] => Hall Enstein 
    [4622] => Function Areas 
    [4623] => Dining Areas 
    [4624] => Events 
    [4625] => Galleries 
    [4626] => Custom Pages 
    [4627] => News 
    [4629] => Promotions
);

How to get result like [4622] => Function Areas with the search keyword like f or fu . I use array_intersect() function for this requirment. But here I have to search with the keyword "Function Areas" , not f or fu . With f or fu , search result [4622] => Function Areas is not coming. If any one know it, please help me. Thank you

Answer 1

You could use array_filter() to filter the array:

$output = array_filter($yourArray, function($v) { 
  return stristr($v, 'fu'); 
});

Would output:

array
  4622 => string 'Function Areas' (length=14)

Answer 2

There is no standard function to search for a partial match within the array values. You need to define a function here is a handy one using the array_filter function mentioned by @billyonecan:

function array_match_string($haystack, $needle){
    return array_filter($haystack, function($value) use ($needle){
        return stripos($value, $needle) !== false; 
    });
}

You can than simply call the function with an array and a string to search for:

$result_array = array_match_string($array, 'fu');

Solution with PHP < 5.3 (we need a global helper variable to be visible in the callback):

function array_match_string_pre_php_53($haystack, $needle){
    global $_array_match_string_needle;
    $_array_match_string_needle = $needle;
    return array_filter($haystack, 'array_match_string_callback');
}

function array_match_string_callback($value){
    global $_array_match_string_needle;
    return strpos($value, $_array_match_string_needle) !== false;
}

$result_array = array_match_string_pre_php_53($array, 'Fu');

Answer 3

You can try searching with strpos which returns position of found given keyword and -1 if string does not contain keyword

$fruits = array('apple', 'banana', 'orange');

$found = array(); // every that matches keyword

$keyword = "e"; //searching for letter e

foreach($array as $fruit)
{
    if(stripos($fruit, $keyword) !== -1)
    {
        array_push($found, $fruit);
    }
}

// fruits should now contain apple and orange

Note that code wasn't tested so it can contain syntax errors but principle should work

此要求的另一种方式是，必须在该数组处于循环状态的循环中移动该数组。
$keyword = strtolower(trim($needle)); foreach($array as $key=>$arrayvalue) { $isExists = @preg_match("/$keyword/", $arrayvalue); if($isExists) { $com = sprintf('%s [nid: %d]', ucwords($arrayvalue), $key); $spresults[$com] = ucwords($arrayvalue); } }
