如果<table>包含<a>，则首先获取<tr>＆<a>

Question

I'm stuck on a Simple HTML Dom question...

For each <table> on my webpage I'd like to scan the <table> and check if there is an <a> inside of it. If there is, then echo the first <tr> and <a> else skip and go on to the end <table>.

I started working on it but I'm unsure how to progress or check if there is a <a> in the table...

foreach ($html->find('table') as $name) {
    foreach ($name->find('a') as $elem) {
        echo $elem->plaintext.'<br>';
    }
}

Any ideas?

The code you've shared seems very close. See below to output the first child <tr> of the table, if an <a> element is found, then stop looping through additional <a> elements. What specific problems are you having with your code?

foreach ($html->find('table') as $name) {
    foreach ($name->find('a') as $elem) {
        echo $name->find('tr', 0)->plaintext; // echo first TR element
        echo $elem->plaintext.'<br>'; // echo A element
        break 1; // skip to the next table
    }
}
