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';

alexsasharegan / flexbox.css
Last active December 15, 2023 16:32
Some helpful classes to start using flexbox in your styles. Classes are vendor prefixed, and set up to add one property only—this enables building up styles with class composition. The flexbox class names help convey how the css property will affect your html.
.flex {
display : -webkit-box;
display : -ms-flexbox;
display : flex;
}
.flex-row {
display : -webkit-box;
display : -ms-flexbox;
