Used for generating dynamic text from templates. Commonly used for seo text generation.
$template = 'Lorem ipsum [dolor sit|amet], consectetur adipisicing elit. Aliquid [aut et|expedita|fuga [fugiat|ipsum molestias] neque nesciunt] placeat quasi, quisquam repellat tempora totam. Amet blanditiis [corporis|esse|odio] soluta.';
$ptt = new Ptt([
[ // this rule will take everything inside [], split it by | and
'take' => ['[', ']'], // choose random variant
'split' => '|',
'transform' => function($choices) {
return $choices[rand(0, count($choices) - 1)];
}
]
]);
// Transform function is a callback that takes list of from template and returns selected choice (string).
// Other rules may also be applied to single template
$ptt->addRule([
'take' => ['[%', '%]'],
'split' => '|',
'transform' => function($choices) {
shuffle($choices);
return join('', $choices);
}
]);
// All rules by default has '[',']' as enclosing symbols and '|' set to splitting.
// Also should be noted that before processing all rules sorted by token length so if you have same symbols in your tokens they working correctly.
$text = $ptt->compile($template, [$replace]); // Compile template using this rules
// Optional parameter $replace used for replacing placeholders in template after compiling it.
// By default placeholders enclosed in '<' and '>'. This could be changed with two first params in $replace.
// Full $replace example:
$replace = [
'<', '>', [
'placeholder1' => 'replacement1',
'placeholder2' => 'replacement2'
]
];
// As mentioned above all replacements happens after template compiling, so enclosing symbols should differ from that used in compile rules.Ptt is licensed under the MIT license. Refer to /LICENSE for more information.
