extract specific data from .txt file using regex function-CodePudding

i want to extract some specific data from a txt file with regex, the file look like this :

Facture

i can extract them by calling each line such an array : exmaple : echo $lines[20];

but sometimes the document lignes ares changes so i need to extract them dynamically , i found that regex could help in this situation and i tried but im stacked at this code :

<?php
$file = file_get_contents('./incwo.txt', true);
$lines = explode( "\n" , $file);
$charge_infos['detail']="INCWO";
$charge_infos['description'] = 'ACHATS DE MARCHANDISES';
for($i=0; $i<count($lines);$i   )
{
 $line=$lines[$i];

 if(preg_match('/facture/i', $line) || preg_match('/TVA/i', $line) ) {
 echo  nl2br ( $lines[$i  1] , "\n ");
 } 
}
?>

the result i get :

F2107 98680   // i need this line

2400          // i need this line

and thanks in advance

CodePudding user response：

If I understand your question correctly, you probably don't need regex for this. Try changing

if(preg_match('/facture/i', $line) || preg_match('/TVA/i', $line) )

if(($line == "Facture") || ($line == "TVA") )

and see if it works.
