alexsasharegan / assoc_replace.php
Created August 15, 2016 17:35
Use handlebars-like syntax and do template rendering with associative arrays, where the key is var name, and the value is the rendered content.
<?php
function assoc_replace ($templateStr, $replacementList) {
$searchStrings = [];
$replacements = [];
foreach ($replacementList as $key => $val) {
array_push($searchStrings, '{{'.$key.'}}');
array_push($replacements, $val);
}
return str_replace($searchStrings, $replacements, $templateStr);
}

An easy to include function for connecting to an SQL database. Return the database handle. Fill in your default connection, while allowing for case-by-case connection overrides.
<?php
function db_connect ($options = []) {
if (!empty($options)) {
$hostName = !empty($options['hostName']) ? $options['hostName'] : 'someHostName';
$databaseName = !empty($options['databaseName']) ? $options['databaseName'] : 'someDatabaseName';
$dbUserName = !empty($options['dbUserName']) ? $options['dbUserName'] : 'someUsername';
$dbPassword = !empty($options['dbPassword']) ? $options['dbPassword'] : 'somepassword';
} else {
$hostName = 'someHostName';
