Question

我有一份案文文件,内容很多,我想在带PHP的屏幕上显示其中的一部分内容。

At a certain point there s string like ITEM DESCRIPTION:

What I want to get all content from this string (just after it) to the end of the file.

这是我迄今为止的法典:

$file = "file.txt";
$f = fopen($file, "r");
while ($line = fgets($f, 1000))
  echo $line;

:)

Answer 1

$file = "file.txt";
$f = fopen($file,  rb );
$found = false;
while ($line = fgets($f, 1000)) {
    if ($found) {
       echo $line;
       continue;
    }
    if (strpos($line, "ITEM DESCRIPTION:") !== FALSE) {
      $found = true;
    }
}

Answer 2

How about you use strstr() and file_get_contents() ?

$contents = strstr(file_get_contents( file.txt ),  ITEM DESCRIPTION: );
# or if you don t want that string itself included:
$s = "ITEM DESCRIPTION:"; # think of newlines as well "
", "
", .. or just use trim()
$contents = substr(strstr(file_get_contents( file.txt ), $s), strlen($s));

Answer 3

What about

$file = "file.txt";
$f = fopen($file, "r");
$start = false;
while ($line = fgets($f, 1000)) {
  if ($start) echo $line;
  if ($line ==  ITEM DESCRIPTION ) $start = true;
}

?
