how to make a php page that edits and clears another PHP file - Crazer - May 12, 2012
Ok so I would need
/admin/logs.php
to view and be able to edit
../logs/log.php but after lets say the 5th line of code.
I would like to to clear it also and remove ALL text after line 5, But lines 1-5 should not be touched.
also i need
/admin/indexfile.php
to view and edit
../index.php
but the whole file.

Give this a go. I've not tested it at all so there a very good chance I've missed something. It's just the first one.
PHP Code
<?php
$separator = '// Edit below //';
$keep = array(
'Line 1',
'Line 2',
'Line 3',
'Line 4',
'Line 5',
$separator
);
if(isset($_POST['submit'])) {
$content = implode(PHP_EOL, $keep) . PHP_EOL . $_POST['content'];
if(file_put_contents($file, $content)) {
echo '<h1>Done</h1>';
} else {
echo '<h1>Oops</h1>';
}
}
$file = 'log.php';
$lines = file($file);
$current = array();
$result = array();
$editable = false;
for($x = 0; $x < count($lines); $x++) {
if(strpos(strtolower($lines[$x]), strtolower($separator)) != false) {
$editable = true;
}
if($editable) {
$current[] = $lines[$x];
}
}
echo '<form action="" method="post">';
echo '<textarea name="content">';
foreach($current as $line) {
echo "{$line}<br />";
}
echo '</textarea>';
echo '<input type="submit" name="submit"';
echo '</form>';

Here is my version, you could put it into a function if you want.
Code
<?php
$log = fopen("logs/log.php", "r");
$t = array();
for($i=0; $i<5; $i++) {
$t[] =fgets($log);
}
fclose($log);
$log = fopen("logs/log.php", "w");
foreach($t as $v) {
fwrite($log, $v);
}
//Write your stuff
fwrite($log, "Test");
fclose($log);
?>benefit of my code is that it's dynamic.
EDIT: Meh just reread what you wanted. Anyway, you could incorporate mine into his to make his dynamic.

Here we go, try this: (its based off of mine and his)
Code
<?php
$log = fopen("logs/log.php", "r");
$t = "";
for($i=0; $i<5; $i++) {
$t .= fgets($log);
}
fclose($log);
if(isset($_POST["submit"])) {
$content = $_POST['content'];
file_put_contents("logs/log.php", $t . $content);
}
echo '<form action="index.php" method="post">';
echo '<textarea style="width:50%;height:50%" name="content">';
echo file_get_contents("logs/log.php", NULL, NULL, strlen($t));
echo '</textarea>';
echo '<input type="submit" name="submit">';
echo '</form>';

Just wondering, did mine work okay? Since I never actually tested it I don't know for sure!

$filepath = 'path/to/file'
file_put_contents($filepath, implode(array_slice(file($filepath), 0, 5)));
