Question

I have a paragraph below, that I want from it is the first word of every end of a period.

$paragraph="Microsoft is writing down $6.2 billion of the goodwill within its OSD. It's worth noting that at the time of the acquisition, the company recorded $5.3 billion of goodwill assigned to the OSD, bringing its total carrying balance up to $5.9 billion in September of that year. The goodwill in the OSD had climbed up to $6.4 billion by March of this year, so this accounting charge is wiping out the vast majority of that figure.";

for example, I can do this.

$sentences=explode('.',$paragraph);
print_r( $sentences);

and it prints

Array ( [0] => Microsoft is writing down $6
        [1] => 2 billion of the goodwill within its OSD 
        [2] => It's worth noting that at the time of the acquisition, the company recorded $5 
        [3] => 3 billion of goodwill assigned to the OSD, bringing its total carrying balance up to $5                            
        [4] => 9 billion in September of that year 
        [5] => The goodwill in the OSD had climbed up to $6 
        [6] => 4 billion by March of this year, so this accounting charge is wiping out the vast majority    of that figure 
        [7] => )

however, I was wandering how can one get the first word from every array.
for example how is it possible to create a function that will get the first word like the example below:

Microsft
2
it’s
3
9
The
4

Thanks

Answer 1

Use explode() on each sentence, but use a space, instead of a period.

$paragraph = "Microsoft is writing down $6.2 billion of the goodwill within its OSD. It's worth noting that at the time of the acquisition, the company recorded $5.3 billion of goodwill assigned to the OSD, bringing its total carrying balance up to $5.9 billion in September of that year. The goodwill in the OSD had climbed up to $6.4 billion by March of this year, so this accounting charge is wiping out the vast majority of that figure.";

$sentences = explode('.', $paragraph);

foreach($sentences as $sentence){
 $words = explode(' ', trim($sentence));
 $first = $words[0];
 echo $first;
}
