在PHP中，如何将这个简单的文本块解析为多维数组？
我有一个简单的文本块；其内容是： txt_1(val_1,val_2,val_3). txt_1(val_4,val_5,val_6). txt_2(val_7,val_8,val_9). txt_3(val_10,val_11,val_12). txt_3(val_13,val_14,val_15). txt_4(val_16,val_17,val_18). 现在，我想解析到这个PHP数组中，比如：在PHP中，如何将这个简单的文本块解析为多维数组？,php,arrays,parsing,Php,Arrays,Parsing,我有一个简单的文本块；其内容是： txt_1(val_1,val_2,val_3). txt_1(val_4,val_5,val_6). txt_2(val_7,val_8,val_9). txt_3(val_10,val_11,val_12). txt_3(val_13,val_14,val_15). txt_4(val_16,val_17,val_18). 现在，我想解析到这个PHP数组中，比如： Array ( [txt_1] => A
Array
(
[txt_1] => Array
(
[0] => Array
(
[0] => val_1
[1] => val_2
[2] => val_3
)
[1] => Array
(
[0] => val_4
[1] => val_5
[2] => val_6
)
)
[txt_2] => Array

)
[txt_3] => Array

[1] => val_11
[2] => val_12

[txt_4] => Array
(
[0] => Array
(
[0] => val_16
[1] => val_17
[2] => val_18
)
)
)
在这里测试它：
<?php
// Initially put your input into a variable
$txt=<<<__EOT__
txt_1(val_1,val_2,val_3).
txt_2(val_4,val_5,val_6).
txt_n(val_a,val_b,val_c).
__EOT__;
$result = array();
// separate out each row
$rows = explode("\n", $txt);
// loop through each row
foreach($rows as $row) {
// Use a regular expression to find the key and values
$success = preg_match('/^([^(]+)\(([^)]+)\)\.$/', $row, $parts);
// Check the regexp worked
if(!$success) {
echo 'Failed to match row: ' . $row . "\n";
continue;
}
// get the array key from the regexp results
$key = $parts[1];
// the values are all a string, split on the comma to make an array
$values = explode(',', $parts[2]);
// store $key and $values in the result
$result[$key] = $values;
}
// See if it worked
var_dump($result);
注意：要使用短数组语法[]，请使用PHP5.4
<?php
$text = "
txt_1(val_1,val_2,val_3).
txt_2(val_4,val_5,val_6).
txt_n(val_a,val_b,val_c).
";
$myArray = [];
//You're gonna see why we want to remove this character
//later, it will help us have a cleaner code.
$text = str_replace(')', '', $text);
$arrayGroup = explode('.', $text);
//print_r($arrayGroup);
foreach($arrayGroup as $array) {
$exp = explode('(', $array);
$arrayName = trim($exp[0]);
$arrayValues = explode(',', $exp[1]);
foreach($arrayValues as $value) {
${$arrayName}[] = $value;
}
$myArray[$arrayName] = $$arrayName;
}
echo '<pre>';
print_r($myArray);
echo '</pre>';
echo '<pre>';
print_r($myArray['txt_2']);
echo '</pre>';
假设这个答案对你有帮助
$text=”
txt_1（val_1，val_2，val_3）。
txt_2（val_4、val_5、val_6）。
txt_3（val_a、val_b、val_c）。
";
$myArry=explode（“.”，$text）；
$resArry=array（）；
foreach（$myArry作为$key=>$value）{
如果（修剪（$value）！=“”）{
$plain=str_replace（数组（“（“，”），“，”，$value）；
$subary=分解（“，”，$plain）；
$keyN=分解（“（”，修剪（$value））；
未设置（$subary[array_search（$keyN[0]，$subary）]）；
未设置（$subary[array_search（“，$subary）]）；
$resArry[$keyN[0]][]=$subArry；
}
}

//输出将类似于
排列
(
[txt_1]=>数组
(
[0]=>阵列
(
[1] =>val_1
[2] =>val_2
[3] =>val_3
)
)
[txt_2]=>数组
(
[0]=>阵列
(
[1] =>val_4
[2] =>val_5
[3] =>val_6
)
)
[txt_3]=>数组
(
[0]=>阵列
(
[1] =>val_a
[2] =>val_b
[3] =>val_c
)
)
)
这是$final
的输出
你测试过答案吗？@Viral我想这个答案也适用于动态数组，比如txt_1（val_1，val_2，val_3）。txt_1（val_4，val_5，val_6）。txt_2（val_7，val_8，val_9）。txt_3（val_10，val_11，val_12）。txt_3（val_13，val_14，val_15）。txt_4（val_16，val_17，val_18）。
<?php
$text = "
txt_1(val_1,val_2,val_3).
txt_2(val_4,val_5,val_6).
txt_n(val_a,val_b,val_c).
";
$myArray = [];
//You're gonna see why we want to remove this character
//later, it will help us have a cleaner code.
$text = str_replace(')', '', $text);
$arrayGroup = explode('.', $text);
//print_r($arrayGroup);
foreach($arrayGroup as $array) {
$exp = explode('(', $array);
$arrayName = trim($exp[0]);
$arrayValues = explode(',', $exp[1]);
foreach($arrayValues as $value) {
${$arrayName}[] = $value;
}
$myArray[$arrayName] = $$arrayName;
}
echo '<pre>';
print_r($myArray);
echo '</pre>';
echo '<pre>';
print_r($myArray['txt_2']);
echo '</pre>';
Suppose this answer will help you
$text = "
txt_1(val_1,val_2,val_3).
txt_2(val_4,val_5,val_6).
txt_3(val_a,val_b,val_c).
";
$myArry = explode(".", $text);
$resArry = array();
foreach ($myArry as $key => $value) {
if(trim($value)!=""){
$plain = str_replace(array("(",")"),",",$value);
$subArry = explode(",",$plain);
$keyN = explode("(",trim($value));
unset($subArry[array_search($keyN[0],$subArry)]);
unset($subArry[array_search("",$subArry)]);
$resArry[$keyN[0]][]=$subArry;
}
}
echo "<pre/>";
print_r($resArry);
die;
