如何检查一组字是否在字符串中与PHP

Question

所以我有下面的代码，但我想知道如何判断'$ text'是否包含'所有者'这些字。我该怎么做呢？我环顾四周，但我找不到任何东西。

foreach($anchors as $a) { 
    $i = $i + 1; 
    $text = $a->nodeValue; 
    $href = $a->getAttribute('href'); 
    if ($i > 22 && $i < 64 && ($i % 2) == 0) { 
     //if ($i<80) { 
     echo "<a href =' ".$href." '>".$text."</a><br/>"; 
    } 
    // } 
     //$str = file_get_contents($href); 
//$result = (substr_count(strip_tags($str),"ipod")); 
//echo ($result); 
}

喜欢的东西：

$text = $a->nodeValue; 
if(strpos($text, "by owner") == -1){ // if you want the text to *start* with "by owner", you can replace this with strpos($text, "by owner") != 0 
    echo "Doesn't have by owner"; 
} 
else{ 
    echo "Has by owner"; 
}
