我正在尝试在强标记中搜索关键字。
我为标签生成了一个数组,显示为:
Array
(
[0] => Array
(
[0] => seo agency in london
[1] => seo agency in london
[2] => seo consultant in london
[3] => seo consultant in london
[4] => seo experts in london
)
[1] => Array
(
[0] => seo agency in london
[1] => seo agency in london
[2] => seo consultant in london
[3] => seo consultant in london
[4] => seo experts in london
)
)
我想搜索关键字,在这种情况下是“seo”
我正在使用:
function substr_count_array( $haystack, $needle ) {
$count = 0;
foreach ($needle as $substring) {
$count += substr_count( $haystack, $substring);
}
return $count;
}
$matchPattern7 = '/<strong(?:"(?:[^\\\"]|\\\.)*"|\'(?:[^\\\\\']|\\\.)*\'|[^\'">])*>(.*?)<\/strong>/';
preg_match_all($matchPattern7, $content, $foundIt7);
echo substr_count_array(strtolower($foundIt7), strtolower($keyword));
供参考..
$ keyword = seo
我变零,有人可以帮忙吗?感谢

function substr_count_array( $haystack, $needle ) {
$count = 0;
foreach ( $haystack as $substring) {
foreach($substring as $string)
{
$count += substr_count($string, $haystack);
}
}
return $count;
}

经过测试并适合我:
$foundIt7=array();
$foundIt7[1]=array(0 => ' seo agency in london',
1 => 'seo agency in london',
2 => 'seo consultant in london',
3 => 'seo consultant in london',
4 => 'seo experts in london');
print_r($foundIt7[1]);
function substr_count_array( $haystackAr, $needle ) {
$count = 0;
foreach ($haystackAr as $haystack) {
$count += substr_count( $haystack, $needle);
}
return $count;
}
echo substr_count_array($foundIt7[1],'seo');//returns 5
