Search word with file_get_contents

Question

How can I use file_get_contents to search for the word "team" on the site and if it locates the word echo in the word?

<?php

$content = file_get_contents( 'https://www.hostgator.com.br' );

$busca = 'equipe ';

?>

Answer 1

Can use preg_match_all() to make this search, the results are stored in the third argument($matches).

<?php
   $content = file_get_contents( 'https://www.hostgator.com.br' );
   $regex = '/equipe/';
   preg_match_all($regex, $content, $matches);

   echo "<pre>";
   print_r($matches);

Answer 2

Use the function strpos to find the first occurrence of the string.

$content = file_get_contents( 'https://www.hostgator.com.br' );


if (strpos($content, 'equipe') !== FALSE) {
    echo "tem a palavra";
}

In case I need to find the word independent of upper or lower case, you can use stripos.

Usually regular expressions are slower. If the string is just a specific word, you can choose strpos, which is simpler.

It can be done in the following ways, and it also has many other forms:

In the first one going line by line and giving echo in the words found:

<?php

$fileContent = file_get_contents('https://pt.wikipedia.org/wiki/Equipe');

foreach (preg_split('/\n/', $fileContent) as $value) {

  $pattern = '/equipe/';//Padrão a ser encontrado na string $fileContent
  if (preg_match_all($pattern, $value, $matches)) {

    foreach ($matches[0] as $matche) {

      echo $matche . '<br>';

    }

  }

}

Or also this way searching the entire string:

<?php

$fileContent = file_get_contents('https://pt.wikipedia.org/wiki/Equipe');

$pattern = '/equipe/';//Padrão a ser encontrado na string $value
if (preg_match_all($pattern, $fileContent, $matches)) {

  foreach ($matches[0] as $matche) {
    echo $matche . '<br>';
  }

}
