用php或者laravel怎么切割一个文件？
比如，有个location.blade.php

    <div class="card-block">
        <div class="row">
            <div class="col-1">北京</div>
            <div class="col-11">
                <a href="#" class="card-link">东城</a>
                <a href="#" class="card-link">西城</a>
                <a href="#" class="card-link">朝阳</a>
                <a href="#" class="card-link">海淀</a>
            </div>
        </div>
    </div>
    <div class="card-block">
        <div class="row">
            <div class="col-1">上海</div>
            <div class="col-11">
                <a href="#" class="card-link">黄浦</a>
                <a href="#" class="card-link">卢湾</a>
                <a href="#" class="card-link">徐汇</a>
                <a href="#" class="card-link">长宁</a>
            </div>
        </div>
    </div>
    <div class="card-block">
        <div class="row">
            <div class="col-1">天津</div>
            <div class="col-11">
                <a href="#" class="card-link">和平</a>
                <a href="#" class="card-link">河东</a>
                <a href="#" class="card-link">河西</a>
                <a href="#" class="card-link">南开</a>
            </div>
        </div>
    </div>

我想写个脚本，把它切割成三个文件：
beijing.blade.php

    <div class="card-block">
        <div class="row">
            <div class="col-1">北京</div>
            <div class="col-11">
                <a href="#" class="card-link">东城</a>
                <a href="#" class="card-link">西城</a>
                <a href="#" class="card-link">朝阳</a>
                <a href="#" class="card-link">海淀</a>
            </div>
        </div>
    </div>

shanghai.blade.php

    <div class="card-block">
        <div class="row">
            <div class="col-1">上海</div>
            <div class="col-11">
                <a href="#" class="card-link">黄浦</a>
                <a href="#" class="card-link">卢湾</a>
                <a href="#" class="card-link">徐汇</a>
                <a href="#" class="card-link">长宁</a>
            </div>
        </div>
    </div>

tianjin.blade.php

    <div class="card-block">
        <div class="row">
            <div class="col-1">天津</div>
            <div class="col-11">
                <a href="#" class="card-link">和平</a>
                <a href="#" class="card-link">河东</a>
                <a href="#" class="card-link">河西</a>
                <a href="#" class="card-link">南开</a>
            </div>
        </div>
    </div>

    $Simple    = array_filter(explode('<div class="card-block">', $fileInfo));
    $tempArray = array_map(function ($val) {

    ];

    //each
    foreach ($tempArray as $value) {
        foreach ($corresponding as $_key => $_value) {
            if (!strpos($_key, $value)) {
                $file = null;
                $file = new  \SplFileObject(DIR . $_value, 'w+');
                $file->fwrite(mb_convert_encoding($value,'HTML-ENTITIES',"UTF-8"));
            }
        }
    }
    //off file object
    $file = null;
}
