If no messages were found in an array then it is returning 2 instead of null PHPI am appending messages to array and calling functions to append array but while calling the functions there were no messages found in array also it is showing them as 2 value those are Array ( [0] => [1] => ) \[code\]$errorMessages = array (); $isError = false; $middleName = $_POST [ 'middleName' ]; $middleName = trim( stripslashes( $middleName ) ); //validation for warrant id $warrantId = $_POST [ 'warrantId' ]; if ( $warrantId == null || ( strlen( $warrantId ) ) <= 0 ) { $errorMessages[] = "Warrant Id is required"; } else { $message = 'enter keyboard characters only for warrant Id.'; $warrantId = trim( stripslashes( $warrantId ) ); $x = checkLength($warrantId, 'WarrantId', 1); $errorMessages[] = $x; //$errorMessages[] = checkRegEx( $warrantId, '/^([a-zA-Z0-9._\- #,^&`~<>:!@$(){}\"\';\*\[\]?%| \n \r \t]*)$/', $message ); } $errorMsg = count($errorMessages); print_r($errorMsg);\[/code\]functions \[code\]/** Checks the field length is not greater than allowed length* @params unknown values $fieldValue, $fieldName, $maxLength* @return tables rows $rowResponse*/function checkLength($fieldValue, $fieldName, $maxLength) { $errorMsg = NULL;if (strlen ( $fieldValue ) > $maxLength) { $errorMsg = $fieldName . " cannot be greater than " . $maxLength .
