PHP if statement as variable - php

Question

I have a variable ($statement) that will store dynamic content like the below:
($row[Gender] == "Female") && ($row[Grade] == "A" || $row[Grade] == "B" || $row[Grade] == "C1") && ($row[Race] == "African" || $row[Race] == "Coloured" || $row[Race] == "Indian" || $row[Race] == "White")
I want to then use this $statement in a if condition like so: if ($statment) {do logic here...}. This is used to match values in an array held in $row (e.g. $row[Gender] which has the value "Male").
Is this achievable and what's the best way to do it?
The whole method() is:
public function ApplyRuleset ($activeOpportunity, $step, $companyId, $projectId, $phaseId) {
// Get global vars
global $conn;
// Get non declined employees for this opportunity only
$getAllCandidates = $this->GetTalentPool ("normal", $step, $activeOpportunity[0]['oppID'], $companyId, $projectId, $phaseId);
// Get column slices
$columnSlices = GetSlices ($conn, $companyId, $projectId, $phaseId, 0);
// Split ruleset into manageable parts
$columnSets = explode (" AND ", $activeOpportunity[0]['rule']);
echo "<pre>";
// Check that we have all that we need
if (is_array ($getAllCandidates) && is_array ($columnSlices) && is_array ($columnSets)) {
// Get selected talent pool
foreach ($getAllCandidates as $row) {
// Format business rules
foreach ($columnSlices as $sliceValue) {
// Get the slices to match which facets were selected
$qualifiedName = preg_replace ('/\s+/', "", $sliceValue['facet']);
// Loop through column match
foreach ($columnSets as $set) {
// Get olumn match
$ruleMatch = explode (" -> ", $set);
$columnName = $ruleMatch[0];
$options = explode (",", $ruleMatch[1]);
// Match rule
for ($i = 0; $i < count ($options); $i++) {
// Write conditional statement
$statement .= '("$row[' . $columnName . ']" == "' . $options[$i] . '"';
$statement .= (count ($options) > 1 && $options[$i] !== end ($options)) ? " || " : ") && (";
}
}
break;
}
// Finalise statement
$editStatement = preg_replace ("/ && \($/", "", $statement);
$editStatement = preg_replace ("/ \(/", " ", $editStatement);
$editStatement = preg_replace ('/"\$/', "$", $editStatement);
$finaliseStatement = preg_replace ('/\]"/', "]", $editStatement);
// Do record match
if ($finaliseStatement) {
// Record matches, load into match array
$this->rulesetMatch[] = $row;
// Set required vars
$_REQUEST['selected'] = (array) $row[candidateId];
$_REQUEST['opportunityID'] = $activeOpportunity[0]['oppID'];
$_REQUEST['step'] = $step;
// Insert these records for round 1
//$this->AddCandidatesToOpportunity ();
}
}
}
// Return all the rows that matched and dedupe
return array_map ("unserialize", array_unique (array_map ("serialize", $this->rulesetMatch)));
}

You can use the result of the if in a variable called $statement like
$statement = (($row[Gender] == "Female") && ($row[Grade] == "A" || $row[Grade] == "B" || $row[Grade] == "C1") && ($row[Race] == "African" || $row[Race] == "Coloured" || $row[Race] == "Indian" || $row[Race] == "White"));
and then you can use this result in if statement as you wish
if ($statement === true) {
// ...
}
