PHP是一种广泛应用于Web开发的脚本语言,其对文件的读写操作非常灵活和强大。本教程将为大家介绍PHP中常用的文件读取和写入方法,并提供一些实用的代码示例,帮助开发者快速掌握这些技巧。
$file_path = "example.txt"; $file_content = file_get_contents($file_path); echo $file_content;
$file_path = "example.txt";
$file_handle = fopen($file_path, "r");
<p>while (!feof($file_handle)) {<br>
$line = fgets($file_handle);<br>
echo $line;<br>
}</p>
<p>fclose($file_handle);<br>
$file_path = "example.csv";
$file_handle = fopen($file_path, "r");
<p>$data = array();<br>
while (($line = fgetcsv($file_handle)) !== false) {<br>
$data[] = $line;<br>
}</p>
<p>fclose($file_handle);<br>
print_r($data);<br>
$file_path = "example.txt"; $file_content = "Hello, world!"; file_put_contents($file_path, $file_content);
$file_path = "example.txt"; $file_handle = fopen($file_path, "a"); $file_content = "This is a new line."; fwrite($file_handle, $file_content); fclose($file_handle);
$file_path = "example.csv";
$file_handle = fopen($file_path, "w");
<p>$data = array(<br>
array("Name", "Age", "Email"),<br>
array("John Doe", "30", "<a class="cursor-pointer" rel="noopener">johndoe@example.com</a>"),<br>
array("Jane Smith", "25", "<a class="cursor-pointer" rel="noopener">janesmith@example.com</a>")<br>
);</p>
<p>foreach ($data as $line) {<br>
fputcsv($file_handle, $line);<br>
}</p>
<p>fclose($file_handle);<br>
