insert new string line after some strine line

[hanpedro]

I want insert new string line after some strine line.

I can't understand how I can get the string line which has the words that I am looking for, and how I can handle it.

This is what I a studying, please help me.

================================================

let sys.dat file as follows;

mb_nick varchar(255) NOT NULL default '',
mb_nick_date date NOT NULL default '0000-00-00',
mb_email varchar(255) NOT NULL default '',
mb_homepage varchar(255) NOT NULL default '',
mb_password_q varchar(255) NOT NULL default '',
mb_password_a varchar(255) NOT NULL default '',
mb_level tinyint(4) NOT NULL default '0',
mb_jumin varchar(255) NOT NULL default '',
mb_sex char(1) NOT NULL default '',
mb_birth varchar(255) NOT NULL default '',

add two lines after $find_a1 and $find_a2

<?

$find_a1 = "mb_email";
$find_a2 = "mb_jumin";
$add_line1 = "mb_email_personal varchar(255) NOT NULL default '',"
$add_line2 = "mb_jumin_personal varchar(255) NOT NULL default '',"

$fp = fopen("data/sys.dat", "r+");

while($buf = fgets($fp)){

if ($finded_string = stripos($buf,$find_a1)) {
$finded_string .= $find_a1."n".$new_data."n";
fputs($fp, "$finded_string");
}
}
?>

Or, just do:

<?php

$find['a1'] = 'mb_email';
$find['a2'] = 'mb_jumin';
$add['a1'] = "mb_email_personal varchar(255) NOT NULL default '',";
$add['a2'] = "mb_jumin_personal varchar(255) NOT NULL default '',";

// Load the file into an array
$lines = file('data/sys.dat');

foreach($find as $key=>$needle)
{
    $insert = $add[$key];
	$found = false;

foreach($lines as $key => $line)
{
	if($needle == substr($line, 0, strlen($needle)))
		$found = $key;
}

if($found === false)
    $length = 0;
else
    $length = $found+1;

if($length > 0)
{
	$first_half = array_slice($lines, 0, $length);
	$second_half = array_slice($lines, $length);
}
else
{
	$first_half = array();
	$second_half = $lines;
}    

$first_half[] = $insert;
$lines = array_merge($first_half, $second_half);
}

$data = implode("\n", $lines);

$fp = fopen('data/sys.dat', "w+b");
if(!fwrite($fp, $data))
	echo 'Unable to write data!!';
else
	echo 'Data file written successfully!';
fclose($fp);

?>

That works for me. Goes from a 10-line dat file to a 12-line dat file with the new additions 😉
