Find and delete row in file

[dreamwest]

Im trying to edit a file where some lines end the same way:

 

.....line1..example/line

.....line2..example/line

 

How can i find and delete these specific lines from a file?

 

All ive got so far is the file open:

 

<?php
$file = fopen("example.txt", "r") or exit("Unable to open file!");
//Output a line of the file until the end is reached
while(!feof($file))
  {
  echo fgets($file). "<br />";
  }
fclose($file);
?>

Load the file in string, use str_replace, write string to the file.

Dont know if that will work, that will only take off the similar endings not the whole line

 

Each line is different except for the ending :

 

line 1 description| example ending

line 2 has separate description but same ending | example ending

line 3 is different to line 1 &2 also has a different ending | dont delete this line

 

I just want to delete the whole line that contains "example ending"

//Output a line of the file until the end is reached
if( file_exists( "example.txt" ) )
{
$fileContents = file( "example.txt" );
$searchFor = "hello";
for( $i = 0; $i < count( $fileContents ); $i++ )
{
	if( strstr( $fileContents[$i], $searchFor ) )
		unset( $fileContents[$i] );
}

echo implode( "<br />", $fileContents );
}
else
{
echo "File doesn't exist.";	
}

 

You'll obviously have to save the file afterwards, but I thought for testing you're best to leave it out until you're happy.

Then load it to array as 1 strin is 1 line, use str_replace on every variable, write array to the file.
