我不会修改文件,而是解析它,而是更改 PHP 中的数据,然后重写文件。
为此,我将首先创建一个将输入解析为 php 数组的函数:
function parse($file) {
$records = array();
foreach(file($file) as $line) {
if(preg_match('~^Name: (.*),~', $line, $matches)) {
$record = array('name' => $matches[1]);
}
if(preg_match('~^Age: (.*),~', $line, $matches)) {
$record ['age'] = $matches[1];
}
if(preg_match('~^Date: (.*)\|\|~', $line, $matches)) {
$record ['date'] = $matches[1];
$records [] = $record;
}
}
return $records;
}
其次,我将创建一个函数,将数组再次展平为相同的文件格式:
function flatten($records, $file) {
$str = '#Start#';
$str .= "\n\n";
$str .= 'No. of records: ' . count($records) . "\n\n";
foreach($records as $record) {
$str .= 'Name: ' . $record['name'] . ",\n";
$str .= 'Age: ' . $record['name'] . ",\n";
$str .= 'Date: ' . $record['name'] . "||\n\n";
}
file_put_contents($file, $str . '#End#');
}
然后像这样使用它:
$records = parse('your.file');
var_dump($records);
$records []= array(
'name' => 'hek2mgl',
'age' => '36',
'date' => '07/11/2013'
);
flatten($records, 'your.file');
