Jumping to a point in a text file

[HarryMW]

Hi there,

 

I need to know how to code a php file, to jump to a specific point in  a text file.

 

I haven't a clue what you would use and need the file to do very simply, or so it seems to find the line starting with: "!CLIENTS", then go to the next line and take the information from thereon out UNTIL it reaches a blank line, where it would dis-regard it and stop.

 

Is that possible?

!VOICE

voicename:hostname:otherinfo:otherinfo:otherinfo:

voicename:hostname:otherinfo:otherinfo:otherinfo:

voicename:hostname:otherinfo:otherinfo:otherinfo:

voicename:hostname:otherinfo:otherinfo:otherinfo:

 

!CLIENTS

clientinfo:clientinfo:clientinfo:clientinfo:clientinfo:

clientinfo:clientinfo:clientinfo:clientinfo:clientinfo:

clientinfo:clientinfo:clientinfo:clientinfo:clientinfo:

clientinfo:clientinfo:clientinfo:clientinfo:clientinfo:

 

Theres an example, the datachunks are separated by the ":" character.

Although I am certain there are more 'elegant' ways, here is a VERY rough 'sledge-hammer' approach. It presumes your text file will always follow that format.

 

<?PHP
$file = "data.txt";
$haystack = file_get_contents($file);
$needle = "!VOICE";
$my_array = explode($needle,$haystack);
$haystack = $my_array[1];
$needle = "!CLIENTS";
$my_array = explode($needle,$haystack);
$haystack =$my_array[0];
$haystack = str_replace("\n", "|", $haystack);
$array_01 = explode("|", $haystack);
array_shift($array_01);
array_pop($array_01);
array_pop($array_01);
$nc = count($array_01);
for($i=0;$i<$nc;$i++) {
$temp_array = explode(":",$array_01[$i]);
print_r($temp_array);
echo "<hr>";
}
?>

Hi there,

 

Thank you for what you have pulled up and yes it works for that purpose, however all I need the code to do is go to the specific line starting "!CLIENTS", jump down a line- and pull the information from there on out until it reaches an empty line, where it will stop.

 

This is so the query that will update and insert records if needed will only work for that block of information. Doesn't need to be outputted at that point.

 

Harry.

Do you have a specific format you're looking for? Give us an example of what you want to end up with.

I'm pretty sure you could use Litebearer's suggested code and work with it, especially if doing queries etc.

Simply formatted data that you can use as you want.
