explode

I have this string: var/log/file.log I eventually want to end up with an array looking like this: Array => [ '1' => 'var', '2' => 'var/log', '3' => 'var/log/file.log' ] I currently have this: <?php $string = 'var/log/file.log'; $array = explode('/', $string); $output = [ 1 => $array[0], 2 => $array[0]. '/' .$array[1], 3 => $array[0]. '/' .$array[1]. '/' .$array[2] ]; echo '<pre>'. print_r($output, 1) .'</pre>'; This feels really counter-intuitive and I'm not sure if there's already something built into PHP that can take care of this. How do I build an array using appending previous value? This

This is not homework: Came across this scenario while working on PHP String Differences and Dynamic Restrictions Given a string of n words how to distribute them into m groups without altering the word sequence? Example 1: String: "My name is SparKot" Groups: 2 (string is split in to two strings) Possible groups will be: ('My', 'name is SparKot'), ('My name', 'is SparKot'), ('My name is', 'SparKot') with the same string Example 2: String: "My name is SparKot" Groups: 3 (string will be split in to three strings) Possible groups will be: ('My', 'name', 'is SparKot'), ('My', 'name is', 'SparKot')

How do I do explode on a column in a DataFrame? Here is an example with some of my attempts where you can uncomment each code line and get the error listed in the following comment. I use PySpark in Python 2.7 with Spark 1.6.1. from pyspark.sql.functions import split, explode DF = sqlContext.createDataFrame([('cat \n\n elephant rat \n rat cat', )], ['word']) print 'Dataset:' DF.show() print '\n\n Trying to do explode: \n'

I'd like to explode a multi-line-string like this color:red material:metal to an array like this $array['color']=red $array['material']=metal any idea? Use explode() , you can use a regexp for it, but it's simple enough without the overhead. $data = array(); foreach (explode("\n", $dataString) as $cLine) { list ($cKey, $cValue) = explode(':', $cLine, 2); $data[$cKey] = $cValue; } As mentioned in comments, if data is coming from a Windows/DOS environment it may well have CRLF newlines, adding the following line before the foreach() would resolve that. $dataString = str_replace("\r", "",

Is there a better way of doing this than looping through the array with a foreach and converting each string to int? 回答1: $integerIDs = array_map('intval', explode(',', $string)); 回答2: This is almost 3 times faster than explode() , array_map() and intval() : $integerIDs = json_decode('[' . $string . ']', true); 回答3: So I was curious

I want to convert that string into an array, and for every new line, jump one index place in the array. If the string is: My text1 My text2 My text3 The result I want is this: Array ( [0] => My text1 [1] => My text2 [2] => My text3 ) 回答1: You can use the explode function, using " \n " as separator : $your_array = explode("\n", $your_string_from_db); For instance, if you have this piece of code : $str = "My text1\nMy text2\nMy text3"; $arr = explode("\n", $str); var_dump($arr); You'd get this
