Return values for appropriate arguments - php

Question

Is here any possible to write single return for both $strValues and $strThumbImages i need to return $strValues for every time but returning $strThumbImages is just when it is available..
function doSelectBranchRecords($objArray,$ImageId = NULL)
{
global $global_config;
$strWhereClause = '';
if ($objArray['frmNameSearch']) {
$strWhereClause.= " AND A.branch_ident = '".$objArray['frmNameSearch']."' ";
}
if ($objArray['frmLoanSearch']) {
$strWhereClause.= " AND A.loan_ident = '".$objArray['frmLoanSearch']."' ";
}
if ($objArray['frmBeneficiarySearch']) {
$strWhereClause.= " AND A.beneficiary_idents = '".$objArray['frmBeneficiarySearch']."' ";
}
if ($objArray['frmDateSearch']) {
$strDate = explode("-", $objArray['frmDateSearch']);
$strAccountstarted = $strDate[2].'-'.$strDate[1].'-'.$strDate[0];
$strWhereClause.= " AND A.account_started = '".$strAccountstarted."' ";
/*printArray($strWhereClause); exit;*/
}
if ($ImageId) {
$strThumbImages = $global_config["SiteGlobalUploadPath"].$ImageId;
return $strThumbImages;
}
$strSqlSelect = "SELECT A.*,B.branch_name FROM tbl_companydetails as A,tbl_branchdetails as B where A.branch_ident=B.branch_id $strWhereClause order by company_id DESC";
$strValues = SelectQry($strSqlSelect);
return $strValues;
}

Answer 1

A php function can't return more than one variable. You could get both results from the function by returning an array with either one or two keys in it, then do a check in your calling code to see what has been set. So the end of your function becomes:
...
}
$output = array();
if ($ImageId) {
$strThumbImages = $global_config["SiteGlobalUploadPath"].$ImageId;
$output['thumbImages'] = $strThumbImages;
}
$strSqlSelect = "SELECT A.*,B.branch_name FROM tbl_companydetails as A,tbl_branchdetails as B where A.branch_ident=B.branch_id $strWhereClause order by company_id DESC";
$strValues = SelectQry($strSqlSelect);
$output['strValues'] = $strValues;
return $output;
}

#Simon and #Suchit are right in that you cannot return more than one variable. But in php it is very straightforwarded to return a list with multiple items like so:
function getXYZ(){
return array(4,5,6);
}
list($x,$y,$z) = getXYZ();
So in your case this could look like so:
$strThumbImages = null;
if ($ImageId) {
$strThumbImages = $global_config["SiteGlobalUploadPath"].$ImageId;
}
$strSqlSelect = "SELECT A.*,B.branch_name FROM tbl_companydetails as A,tbl_branchdetails as B where A.branch_ident=B.branch_id $strWhereClause order by company_id DESC";
$strValues = SelectQry($strSqlSelect);
return array($strValues, $strThumbImages);

As above #Simon Brahan said you can not return more than one variable.
so you can use array with different keys.but you should also check if $ImageId is set and not null.
if (isset($ImageId) && !is_null($ImageId)) {
$strThumbImages = $global_config["SiteGlobalUploadPath"].$ImageId;
$output['thumbImages'] = $strThumbImages;
}
$strSqlSelect = "SELECT A.*,B.branch_name FROM tbl_companydetails as A,tbl_branchdetails as B where A.branch_ident=B.branch_id $strWhereClause order by company_id DESC";
$strValues = SelectQry($strSqlSelect);
$output['strValues'] = $strValues;
return $output;
