Something like SQL "LIKE" but in PHP - php

Question

I have few url in my database, it goes like:
id url
1 http://test.com/embed-990.html
2. http://test2.com/embed-011.html
3. http://test3.com/embed-022.html
How I could make a simple php code if one of url doesn't exist in database, just to load another? I need to check these url by domain as well.
For example something like this:
if($data['url'] == "test.com") {
echo "my embed code number 1";
} elseif($data['url'] == "test2.com") {
echo "my another embed code";
}

Answer 1

You can parse the URL to get the host then compare it.
$dataurl = array('http://test.com/embed-990.html',
'http://test2.com/embed-011.html',
'http://test3.com/embed-022.html');
foreach($dataurl as $url) {
switch(parse_url($url, PHP_URL_HOST)) {
case 'test.com':
echo 'test domain';
break;
case 'test2.com':
echo 'test domain 2';
break;
default:
echo 'unknown';
break;
}
echo $url . PHP_EOL;
}

For the question Something like SQL “LIKE” you could use a regex in preg_match.

Answer 2

You can use substr_count
if (substr_count($data['url'], 'test.com') > 0) {
echo "my embed code number 1";
}
else if (substr_count($data['url'], 'test2.com') > 0) {
echo "my embed code number 2";
}
or strpos
if (strpos($data['url'],'test.com') !== false) {
echo "my embed code number 1";
}
else if (strpos($data['url'],'test2.com') !== false) {
echo "my embed code number 2";
}
or preg_match
if(preg_match('/test.com/',$data['url']))
{
echo "my embed code number 1";
}
else if(preg_match('/test2.com/',$data['url']))
{
echo "my embed code number 2";
}

You can use Regx
$domains = ['test.com', 'test1.com', 'test20.com'];
foreach( $domains as $domain ){
if(preg_match('/test([0-9]*)\.com/', $domain, $match)){
echo "my embed code number {$match[1]}\n";
}
}
Outputs:
my embed code number
my embed code number 1
my embed code number 20
you can test it here

For the regx
test matches test literally
([0-9]*) - capture group, matches 0-9 none or more times
\. matches . literally
com matches com literally
One thing to note is that placing the * outside the capture group ([0-9])* will match and pass the if, but will not capture anything within the capture group. This makes sense, but its important to note because you'll get this message:
Notice: Undefined offset: 1 in [...][...] on line 6
for test.com.
If you want to match the number in embed- You can use one of these
'/test\.com\/embed-([0-9]{3})\.html/'
'/\/embed-([0-9]{3})\.html/'
'/\/embed-([0-9]{3})\./'
Depending how specific you want to be. You can play around with different Regx on this page.

Regular expressions are very powerful, they are meant for pattern matching, which is what you need.
