Int numWantedColumns = wantedColumnNames.size() įor ( int i = 0 i < numWantedColumns ++i) Public static final List toList(ResultSet rs, List wantedColumnNames) throws SQLException * list of maps, one per column row, with column names as keys * list of columns names to include in the result map * Helper method that maps a ResultSet into a list of maps, one per row List wantedColumnNames = getColumnNames(rs) Public static final List toList(ResultSet rs) throws SQLException * list of maps, one per row, with column name as the key * Helper method that converts a ResultSet into a list of maps, one per row 'user='+DB_LOGIN+'&password='+DB_PASSWORD) Public static Connection getDbConnection()Ĭnn = DriverManager.getConnection('jdbc:mysql://'+DB_SERVER+'/'+DB_NAME+'?' + * JDBC connection to MySQL database and map the resultset (create an array associative).

Mapping a resultset into a list of Maps: One Map per database row by setting the Map key name as the database field name by getting the ResultSetMetaData properties and setting the Map value as an objectĪ list object that can be easily iterated through.

#PHP ASSOCIATIVE ARRAY TIMESTAMP HOW TO#

In this PHP Tutorial, we learned about associative arrays in PHP, how to use keys to access of modify elements of Associative Arrays, with the help of example PHP programs.This class handles the JDBC connection to the MySQL database and how to create an array associative in Java from a database Resultset.

#PHP ASSOCIATIVE ARRAY TIMESTAMP UPDATE#

In the following example, we will initialize an associative array, and update the element with key “banana”. sort(timestamparray) You dont need to convert to UNIX timestamps because the strings are in the standard 'ISO sortable date' format. To modify the elements of array using key, assign a new value to the array variable followed by the specific key in square brackets. The value corresponding to the key “banana” is 84 in the array. In the following example, we will create an associative array, and access a value using key.

Add specific number of days to given dateĪDVERTISEMENT Access elements of Associative array.

Find number of days between two given dates.

Catch multiple exceptions in a single catch block.

Uncaught Error: Cannot access protected property.

Define property and method with same name in class.

Delete value at specific index in array.

Filter elements in array based on a condition.

They are also known as maps or dictionaries in other programming languages.

Combine two arrays to create an Associative Array Associative arrays are an essential data structure in PHP that allows developers to store and manipulate collections of values using named keys instead of numeric indexes.

Find index of last occurrence of value in array.

Count occurrences of specific value in array.

Iterate over key-value pairs using foreach.

Check if any two adjacent values are same.

Check if specific element is present in array.

PHP – Convert string array to CSV string.

Check if string has a match for regular expression.

Check if entire string matches a regular expression.

In this tutorial, we will go through the following date/time functions to get the current timestamp. Find all the substrings that match a pattern To get the current timestamp in PHP, we can use date/time functions.Find index of last occurrence in a string.Count number of occurrences of substring in a string.Join elements of string array with separator string.Split string into substrings of specified length.Split string by one or more whitespace characters.Split string by any whitespace character.Trim specific characters from edges of the string.Insert substring at specific index in string.Insert character at specific index in string.Check if string value is a valid number.Check if string contains only uppercase.Check if string contains only lowercase.Check if string contains only numeric digits.Check if string contains only alphabets.Check if string ends with forward slash (/) character.Check if string ends with a punctuation.Check if string starts with a lowercase.Check if string starts with an uppercase.Check if string starts with specific character.Check if string ends with specific substring.Check if string starts with specific substring.Check if string contains specified substring.Check if strings are equal ignoring case.
