Extract The Specific parameter value from array - php

Question

I have a array like this
[0] => Array
(
[0] => LBLdss_COLLEsdfCTIONS_RsdfsdEPORT_TITfsdfLE
[1] =>
[2] =>
[3] => Array
(
[Administration] => Array
(
[bidsflldsf6] => Array
(
[0] => themes/Care2012/images/Payments
[1] => LsdfBL_OPsddfD_BIsfdfsLLING_SsdfdsUMsdfMARY_TITLE
[2] => LsdfsdBL_OPDfdsfd_BILfdsLING_dsfdsSUMMARY
[3] => ./index.php?module=Rsdfepfdsforts&action=reposfdfdsrtsel&rname=Opdpasfdfypdf
)
[bilhghjgl_pat_reg] => Array
(
[0] => themsdfsdes/Casfdfre2aasd012/imasdfges/Pasdymesddfnts
[1] => LBL_sdfsPAT_RsdfEG_TsdfITLE
[2] => LBL_PdfsdAT_sfdREG_TdsfdITLE_DsdfsETAIL
[3] => ./index.php?module=Rexcvpofdsrts&action=reportsel&rname=Pacxvtregcollxcvectionpdf
)
)
)
[4] =>
)
Now i need to extract value of rname from this index [3] => ./index.php?module=Rexcvpofdsrts&action=reportsel&rname=Pacxvtregcollxcvectionpdf (which is Pacxvtregcollxcvectionpdf in this case)and have to save it
I can try explode function but it is heavy for me since my array size is large
please help in resolving this
Thanks

Answer 1

Try placing a foreach for ciclying the array and formulate a regular expression for extract your param. Like this:
foreach($youvar as $text) {
preg_match('$rname=(.+?)$', $text, $rname[])
}
After that you can try a print_r on $rname and adapt to you.

Answer 2

Try below :-
$a = explode("rname=", index[3]);
echo $a[1;]

Answer 3

Code
$array = array(
'./index.php?module=Rsdfepfdsforts&action=reposfdfdsrtsel&rname=Opdpasfdfypdf',
'./index.php?module=Rexcvpofdsrts&action=reportsel&rname=Pacxvtregcollxcvectionpdf',
);
function getRname($str){
//return null if not found
preg_match('/rname\=([a-zA-Z]+)($|&)/', $str , $matches);
return $matches[1];
}
foreach($array as $str){
echo "Rname: " . getRname($str). "<br/>";
}
Result
Rname: Opdpasfdfypdf
Rname: Pacxvtregcollxcvectionpdf
Try it?
