How to search array item with given string

i have an array:

开发者_C百科$mainArr = ["SRI", "AIS", "GOW","SRI#AIS","SRI#GOW", "SRI#GOW#AIS"];

$strArr = ["SRI"];

i want to search the main Array with the given string Array element so that if the string is matched it should get the corresponding key,value pair.

expected o/p would be:

Array[
    0->SRI
    3->SRI#AIS
    4->SRI#GOW
    5->SRI#AIS#GOW
]

Any ideas ?

Thanks, Srinivas

$mainArr = array("SRI", "AIS", "GOW","SRI#AIS","SRI#GOW", "SRI#GOW#AIS");

$strArr = array("SRI");
foreach ($mainArr as $key => $value)
{
    foreach ($strArr as $str)
    {
        if (strpos($value,$str) !== false) $rez[$key] = $value;
    }
}

var_dump($rez);

output:

    array(4) { 
[0]=> string(3) "SRI" 
[3]=> string(7) "SRI#AIS" 
[4]=> string(7) "SRI#GOW" 
[5]=> string(11) "SRI#GOW#AIS" 
} 

I thing i ll help u,,

$test=array();
        $mainArr = array("SRI", "AIS", "GOW","SRI#AIS","SRI#GOW", "SRI#GOW#AIS");
        $strArr = array("SRI");
        foreach ($mainArr as $key => $value)
        {
            $temp   = explode('#',$value);
            //$temp = $temp[0];
            if(in_array($temp[0],$strArr))
            $test[$key]=$value; 
        }
        echo "<pre><span style='color:black; font-size:19;'>";print_r($test);echo "</span></pre>";

Use array_filter:

function filter($element)
{
    return strpos($element, 'SRI') !== false;
}

$mainArr = array("SRI", "AIS", "GOW","SRI#AIS","SRI#GOW", "SRI#GOW#AIS");
$filteredArr = array_filter($mainArr, 'filter');
