我想使用preg_replace函数在其他文件中的php标记启动之后将php代码附加到其他文件中

Question

Here is code

$myFile = "process.php";
$gf = file($myFile);<br>
$data="include('connection.php');"; <br>
foreach($gf as $lineNumber => &$lineContent) { <br>
        if($lineNumber == 0) {<br>
                $lineContent .= $data;<br>
        }<br>
}

$content = implode("", $gf);<br>
file_put_contents($myFile, $content);

Answer 1

You need include the new script on the first php tag ocurrency

$myFile  = "process.php";
$gf      = file($myFile);
$include = "<?php include('connection.php');" . PHP_EOL;


$content = preg_replace("/.*?<?php(?!\w)/", $include, file_get_contents($myFile), 1);

file_put_contents($myFile, $content);
