字符串是：

<div class="item-inner clearfix"> <div class="item-img have-additional clearfix"> <div class="cart-wrap"> <button title="Sәbәtә әlavә et" class="btn-cart" onclick="setLocation('https://az.from.ae/az/checkout/cart/add/uenc/aHR0cHM6Ly9hei5mcm9tLmFlL2F6L2NhdGFsb2dzZWFyY2gvcmVzdWx0L2luZGV4Lz9xPWlwaG9uZSs1cysxNitnYiZjYXQ9MzkmZGlyPWFzYyZvcmRlcj1wcmljZSZsaW1pdD0yNA,,/product/412/form_key/XUXNITbPm6bBkzTQ/')" data-toggle="tooltip" data-original-title="Sәbәtә әlavә et">Sәbәtә әlavә et</button> </div> <div class="item-img-info"> <a href="https://az.from.ae/az/apple-iphone-5s-16-gb-4g-lte-wi-fi-space-gray" title="Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray) Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray)" class="product-image"> <span class="img-main"> <img width="270" height="270" src="https://az.from.ae/media/product/78d/apple-iphone-5s-16-gb-4g-lte-wi-fi-space-gray-buy-apple-iphone-5s-cbf.jpg" alt="Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray) Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray)"/> </span> </a> </div> </div> <div class="item-info"> <div class="info-inner"> <div class="item-title"> <a href="https://az.from.ae/az/apple-iphone-5s-16-gb-4g-lte-wi-fi-space-gray" title="Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray)"> Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray) </a> </div> <div class="item-content"> <div class="item-price"> <div class="price-box"> <span class="regular-price" id="product-price-4128672363671444684686"> <span class="price">AZN  522</span> </span> </div> </div> <p class="no-rating"><a href="https://az.from.ae/az/apple-iphone-5s-16-gb-4g-lte-wi-fi-space-gray/reviews/#review-form">Rəyinizi bildirin</a></p> </div> </div> </div></div>

我的字符串也是这样的：

<div class="item-inner clearfix"> <div class="item-img have-additional clearfix"> <div class="cart-wrap"> <span class="btn-cart availability out-of-stock"><span>Out of stock</span></span> </div> <div class="item-img-info"> <a href="https://az.from.ae/az/apple-iphone-5s-64-gb-4g-lte-wi-fi-gold" title="Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold) Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold)" class="product-image"> <span class="img-main"> <img width="270" height="270" src="https://az.from.ae/media/product/d3e/apple-iphone-5s-64-gb-4g-lte-wi-fi-gold-buy-apple-iphone-5s-2dd.jpg" alt="Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold) Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold)"/> </span> </a> </div> </div> <div class="item-info"> <div class="info-inner"> <div class="item-title"> <a href="https://az.from.ae/az/apple-iphone-5s-64-gb-4g-lte-wi-fi-gold" title="Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold)"> Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold) </a> </div> <div class="item-content"> <div class="item-price"> <div class="price-box"> <span class="regular-price" id="product-price-4166746673391444684602"> <span class="price">AZN  633</span> </span> </div> </div> <p class="no-rating"><a href="https://az.from.ae/az/apple-iphone-5s-64-gb-4g-lte-wi-fi-gold/reviews/#review-form">Rəyinizi bildirin</a></p> </div> </div> </div></div>

我的代码是：

preg_match('/" title="(.*?)">/mis', $product, $names);

它不会返回 Apple iPhone 5S（16 GB，4G LTE + Wi-Fi，Space Grey）？

Answer 1

尝试此模式preg_match('#title="([^"]*)"#', $product, $names);

$names[1]将包含您需要的内容

此外 - 这应该可以帮助您调试此类事情

Answer 2

只需使用preg_match_all("/\" title=\"(.*?)\"/im", $html, $res)，$res[1]就会包含您要查找的内容。
Result：

Array

    [0] => Array
        (
            [0] => " title="Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray) Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray)"
            [1] => " title="Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray)"
            [2] => " title="Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold) Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold)"
            [3] => " title="Apple iPhone 5S (64 GB, 4G LTE + Wi-Fi, Gold)"
        )

    [1] => Array
        (
            [0] => Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray) Apple iPhone 5S (16 GB, 4G LTE + Wi-Fi, Space Gray)

        )
