PHP检查数组是否包含字符串的开头

Question

如何检查给定值的开始是否与预定义值列表中的条目相匹配？

$model_no1 = "KK71458";
$model_no2 = "IX41";

$models = array("KK61", "KK71", "KK81", "IX", "IJ");

在上面的示例代码中，两个值都应该返回一个有效的匹配项。

试试这个:

$model_no1 = "KK71458";
    $models = array("KK61", "KK71", "KK81", "IX", "IJ");
    foreach($models as $key=> $mod){
        if($mod == substr($model_no1,0,strlen($mod))){ 
            echo "key: ".$key.' with value: '.$mod;
        }
    }
