我有以下文本文件（Query1.cif）：
ATOM 1 P P . A A 1 1 1 ? 25.393 -14.093 8.181 1.00 55.25 ? ? ? ? ? ? ? 23 A X P 23 A X P 2
ATOM 2 O OP1 . A A 1 1 1 ? 25.462 -13.992 9.643 1.00 56.56 ? ? ? ? ? ? ? 23 A X OP1 23 A X OP1 2
ATOM 3 O OP2 . A A 1 1 1 ? 25.063 -12.918 7.334 1.00 53.05 ? ? ? ? ? ? ? 23 A X OP2 23 A X OP2 1
我想做的是：
1）阅读文本文件中的每一行
2）检查最后一栏。如果该值不是1，请将其更改为1
3）将所有行保存到新数组中。
我遇到了第三步的问题。我不确定将每一行保存到新数组的正确方法。我还需要访问foreach循环之外的数组值。
以下是pastebin中代码的链接 - http://pastebin.com/PLY9FaLN
//Query 1 would be an array containing the atomic coordinates of motifs/nucleotides of interest
$Query1 = explode("\n", file_get_contents('Query1.cif'));
foreach ($Query1 as $line) {
$line = trim($line);
$line = (explode(" ",$line));
$last_index = count($line) - 1;
echo "</br>"; echo "</br>";
if (strcmp($line[$last_index], '1') !== 0) {
//echo '$var1 is not equal to $var2 in a case sensitive string comparison'."</br>";
$line = str_replace ($line[$last_index], '1', $line);
}
// I need to save each line into an array and access them outside the loop
}
// I want to access the array values here

我的工作做得很好。请注意我使用字符串格式，因为我不想创建一个文件来执行此操作。您仍应使用file_get_contents。
<?php
$query_string = <<<EOD
ATOM 1 P P . A A 1 1 1 ? 25.393 -14.093 8.181 1.00 55.25 ? ? ? ? ? ? ? 23 A X P 23 A X P 2
ATOM 2 O OP1 . A A 1 1 1 ? 25.462 -13.992 9.643 1.00 56.56 ? ? ? ? ? ? ? 23 A X OP1 23 A X OP1 2
ATOM 3 O OP2 . A A 1 1 1 ? 25.063 -12.918 7.334 1.00 53.05 ? ? ? ? ? ? ? 23 A X OP2 23 A X OP2 1
EOD;
$Query1 = explode("\n", $query_string);
$new_arr = [];
//Creates a new array;
foreach ($Query1 as $line) {
$line = trim($line);
//trims the line of any extra spaces
if(strlen($line)==0) continue;
//If this is one of the lines with no characters on it (like the ones between ATOM 1 and ATOM 2, or ATOM 2 and ATOM 3), skip this particular loop
//aka "continue" the loop.
$last_char = substr($line,-1);
//Gets the last character with the substr() function. providing -1 starts at the first character at the end of the string.
if($last_char !== '1'){
//If the last line is a 1, we go into this if
$line = substr_replace($line,'1',-1);
//Replace the substring content of $line, starting at the first character at the end, with '1'.
//This overwrites the last character.
}
$new_arr[] = explode(' ',$line);
//$new_arr[] adds whatever is on the other side of the equal sign to the next index iteration in the array.
//The first call adds the content on the other line to $new_arr[0], the second loop will add it to $new_arr[1], etc.
// I need to save each line into an array and access them outside the loop
}
echo '<pre>';
print_r($new_arr);
echo '</pre>';
// I want to access the array values here
?>
这是浏览器中print_r调用的输出：
