cURL

Veremos neste artigo exemplos de uso para o cURL, acompanhe os detalhes:

Buscando uma página na internet

<?php

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://example.com/");

curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);

curl_close($ch);

?>

Alternativa para a função file_get_contents

file_get_contents

<?php

$file_contents = file_get_contents('http://example.com/');

// display file

echo $file_contents;

?>

Aplicando cURL

<?php

$ch = curl_init();

$timeout = 5; // set to zero for no timeout

curl_setopt ($ch, CURLOPT_URL, 'http://example.com');

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

$file_contents = curl_exec($ch);

curl_close($ch);

// display file

echo $file_contents;

?>

Aplicando cURL (alternativa)

<?php

$site_url = 'http://example.com';

$ch = curl_init();

$timeout = 5; // set to zero for no timeout

curl_setopt ($ch, CURLOPT_URL, $site_url);

curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

ob_start();

curl_exec($ch);

curl_close($ch);

$file_contents = ob_get_contents();

ob_end_clean();

echo $file_contents;

?>

Obtendo dados binários

Imagem

Este script recupera uma imagem remota e atribui os dados binarios na variável $image antes de emitir a imagem para o navegador:

<?php

$image_url = "http://example.com/image.jpg";

$ch = curl_init();

$timeout = 0;

curl_setopt ($ch, CURLOPT_URL, $image_url);

curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

// Getting binary data

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);

$image = curl_exec($ch);

curl_close($ch);

// output to browser

header("Content-type: image/jpeg");

print $image;

?>

Alternativa para a função file

Função File

<?php

$lines = file('http://example.com/');

// display file line by line

foreach($lines as $line_num => $line) {

    echo "Line # {$line_num} : ".htmlspecialchars($line)."<br />\n";

}

?>

Aplicando cURL

<?php

$ch = curl_init();

$timeout = 5; // set to zero for no timeout

curl_setopt ($ch, CURLOPT_URL, 'http://example.com');

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

$file_contents = curl_exec($ch);

curl_close($ch);

$lines = array();

$lines = explode("\n", $file_contents);

// display file line by line

foreach($lines as $line_num => $line) {

    echo "Line # {$line_num} : ".htmlspecialchars($line)."<br />\n";

}

?>
