php 使用fopen与file_get_contents读取文件实例，

<?<span>php
</span><span>$file_name</span> = "1.txt"<span>;
</span><span>echo</span> <span>$file_name</span> . "
"<span>;
</span><span>$fp</span> = <span>fopen</span>(<span>$file_name</span>, 'r'<span>);
</span><span>//</span><span>$buffer=fgets($fp);</span>
<span>while</span> (!<span>feof</span>(<span>$fp</span><span>)) {
    </span><span>$buffer</span> = <span>fgets</span>(<span>$fp</span><span>);
    </span><span>echo</span> <span>$buffer</span><span>;
}
</span><span>fclose</span>(<span>$fp</span><span>);
</span>?>       

<?<span>php
</span><span>if</span> (<span>file_exists</span>(<span>$path</span><span>)) {
    </span><span>$body</span> = <span>file_get_contents</span>(<span>$path</span><span>);
    </span><span>echo</span> <span>$body</span>; <span>//</span><span>输入文件内容</span>
<span>    
} </span><span>else</span><span> {
    </span><span>echo</span> "文件不存在 <span>$path</span>"<span>;
}
</span>?>
