将str_replace与substr结合使用

Question

My conjugation script combines $stamm(2) with all endings from the 2 dimensional array called $array.

part of a foreach loop

$array[3][0] = str_replace($stamm, $stamm2.'o</u>', $value). $red_slash.str_replace($stamm, $stamm2.'ié</u>', $value);

for example

$stamm2='begin';
$stamm3='begin2';
$array[3][0] = array ('irai','iras','ira','irons','irez','iront');

Now I have a case with 2 different regular verb forms with different roots ($stamm2 and $stamm3) but also different endings ($array[3][0]). In the second option should be everytime the first ending letter i deleted.

How is it possible to add substr function or something else what would help me for this part?

str_replace($stamm, $stamm2.'ié</u>', $value);

output: (without the adding the strings o/ié to $stamm2/$stamm3)

beginirai / begin2irai
beginiras / begin2iras
beginira / begin2ira
beginirons / begin2irons
beginirez / begin2irez
beginiront / begin2iront

desired output: (without the adding the strings o/ié to $stamm2/$stamm3)

beginirai / begin2rai
beginiras / begin2ras
beginira / begin2ra
beginirons / begin2rons
beginirez / begin2rez
beginiront / begin2ront

Answer 1

As far as I understood from your desired output, I wrote the following code: (Let me know if I didn't understand you well in the comments section)

$prefix1 = 'begin';
$prefix2 = 'begin2';

$inputArr = array('irai', 'iras', 'ira', 'irons', 'irez', 'iront');
$outputArr1 = array();
$outputArr2 = array();

foreach($inputArr as $input){
 $outputArr1[] = $prefix1 . $input; //for instance: beginirai
 $outputArr2[] = $prefix2 . substr($input, 1); //for instance: begin2rai
}
