Question

i 确信这是一件容易的事,但从扼杀中抽取案文的最佳方式是什么? 例如:

$content = "{hey|hi|hello there}! {i am|i m} {good|great}!";

• 如何使产出如此:

hey! i m good!
hello there! i am great!
etc..

Answer 1

或许可以尝试像:

$content = "{hey|hi|hello there}! {i am|i m} {good|great}!";

$randomOutput = preg_replace( /({.*?})/s , function($matches) {
    $possibilities = (array) explode( | , trim($matches[0],  {} ));

    return $possibilities[array_rand($possibilities)];
}, $content);

PHP <5.3

function randomOutputCallback($matches) {
    $possibilities = (array) explode( | , trim($matches[0],  {} ));

    return $possibilities[array_rand($possibilities)];
}

$content = "{hey|hi|hello there}! {i am|i m} {good|great}!";

$randomOutput = preg_replace( /({.*?})/s ,  randomOutputCallback , $content);

Answer 2

如果你使用一个阵列:

$greeting = array("hey","hi","hello there");
$suffix = array("good","great");

$randGreeting = $greeting[rand(0, sizeof($greeting))];
$randSuffix   = $suffix[rand(0,(sizeof($suffix)))];

echo "$randGreeting, I m $randSuffix!";

当然,你还可以写上最后一行:

echo $randomGreeting . ", I m " . $randSuffix . "!";

Answer 3

我将安排一个阵列的内容...... 诸如

<?php

$responseText = array(
    array("hey","hi","hello there"),
    "! ",
    array("i am", "i m"),
    " ",
    array("good", "great"),
    "! "
);

echo randomResponse($responseText);

function randomResponse($array){
    $result=  ;
    foreach ($array as $item){
        if (is_array($item))
            $result.= $item[rand(0, count($item)-1)];
        else
            $result.= $item;
    }
    return ($result);
}
?>
