How to generate zeros array in php [duplicate]

Question

I need to generate zeros array in php, but don't know how to generate it using php. i can do it using js.

In js array zeros code is:

for (let _i = 0; _i < 25; _i++) {
   let n = new Array(_i).fill(0)
   console.log(n);
}

Generated like this:

[]
[ 0 ]
[ 0, 0 ]
[ 0, 0, 0 ]
[ 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]

<?php $desiredNumber = 25; for ($i=0; $i <= $desiredNumber ; $i++) { $innerArr = array(); for( $j=0; $j <= $i; $j++ ){ array_push($innerArr, 0); } echo '['.implode(', ', $innerArr).']'; echo "<br>"; } ?> — Musabbir Mamun

array_fill()

for ($i = 0; $i < 25; $i++) {
    $n = array_fill(0, $i, 0);
    echo implode(', ', $n) . PHP_EOL; // output imploded for readable reasons
}
