php - How do i start text str_split after some characters

Question

I have the code:

$txt = "lookSTARTfromhereSTARTagainhere";

$disp = str_split($txt, 4); 

for ($b = 0; $b<3; $b++) {
    echo "$disp[$b]"; 
} 

which return 'look', 'STAR' 'Tfor' in a text line of 'lookSTARTfromhereSTARTagainhere' my problem is how do i start my text split from 'START' example my result output for text line of 'lookSTARTfromhereSTARTagainhere' after split look like 'from' 'here' 'again' thanks for your time and understanding

Answer 1

it may not be possible by str_split as 'again' has 5 characters. you can get 'from', 'here' by following code.

$txt = "lookSTARTfromhereSTARTagainhere";
$txt = str_replace('look','',$txt);
$txt = str_replace('START','',$txt);
$disp = str_split($txt, 4); 
for ($b = 0; $b<3; $b++) {
    echo "$disp[$b]"; 
}
