Question

我有一个像这样值的变量:

$sentence = "When it comes time to renew your auto insurance policy, be aware of how your carrier handles renewals";

我有以下值的数组变量:

$searches = array('aware', 'aware of', 'be aware', 'be aware of');

$replaces = array('conscious', 'conscious of', 'remember', 'concentrate on');

我想找到只是“意识到”，然后替换为“专注”。输出如下:

When it comes time to renew your auto insurance policy, concentrate on how your carrier handles renewals

仅搜索“注意”作为相关同义词替换而不是其他同义词。谢谢你的帮助。

好的，这里是新代码:

$searches = array('aware of', 'be aware of', 'be aware', 'aware');

$replaces = array('conscious of', 'concentrate on', 'remember', 'conscious');

这是一个动态数组( $searches )，我希望你理解......我们知道最好的同义词替换是使用“注意”替换为“专注”。输出如下:

When it comes time to renew your auto insurance policy, concentrate on how your carrier handles renewals

怎么样:

$sentence = "When it comes time to renew your auto insurance policy, be aware of how your carrier handles renewals";
$searches = array('aware', 'aware of', 'be aware', 'be aware of');
$replaces = array('conscious', 'conscious of', 'remember', 'concentrate on');

function cmp($a, $b) {
    if (strpos($a, $b) !== false) return -1;
    if (strpos($b, $a) !== false) return 1;
    return 0;
}

uasort($searches, 'cmp');
$replaces_new = array();
$i=0;
foreach($searches as $k=>$v) {
    $replaces_new[$i] = $replaces[$k];
    $i++;
}

$res = str_replace($searches, $replaces_new, $sentence);
echo $res;

输出:

When it comes time to renew your auto insurance policy, concentrate on how your carrier handles renewals
